Microvillositary inclusion disease also known as microvillositary atrophy is a rare congenital enteropathy containing a border abnormality in the brushes of enterocytes, manifesting as severe rebellious diarrhea in newborns and infants. It was first described in 1978 by Davidson, et al. The autosomal recessive mode of transmission is suggested because of the frequency of familial cases and inbreeding. Histopathology plays an essential role in establishing the diagnosis. In 2008, a common mutation was identified in most of the patients studied in the MYO5B gene that codes for the Myosin Vb protein, which helped in understanding the etiopathogeny of this pathology poorly described in the literature. The prognosis for this pathology is extremely bleak, requiring total parenteral nutrition for child survival. Intestinal transplantation is for the moment the only long-term solution. Materials and methods: We report the case of an infant aged 6 months, with no perinatal antecedent. There is 1st degree consanguinity, the mother has a history of deaths in younger siblings in undetermined circumstances. Who since the age of 3 days presents profuse liquid diarrhoea with malnutrition, dehydration and enormous abdominal distension? Several diagnoses were suspected before the jejune biopsy was carried out, which led to the diagnosis of a microvilliositary inclusion disease. The aim of our work is to highlight the rarest cause of neonatal rebel diarrhoea and to know how to include it among other differential diagnoses.

Introduction Choristoma is a mass presenting normal histology, but in an abnormal location. Cystic choristoma is rarely reported in the head and neck region. Neonatal cystic masses in the neck suggest usually correspond to a diagnosis of cystic lymphangioma. Case report We report a case of a congenital cystic choristoma of the neck clinically and radiologically mimicking cystic lymphangioma. Discussion Congenital cystic choristoma is an extremely rare lesion, essentially described in neonates, composed of various types of tissues. The diagnosis of congenital cystic choristoma may be suggested on imaging and must be confirmed by histopathological examination. Treatment consists of complete surgical resection.

Introduction La bilharziose touche plus de 240 millions de personnes a travers le monde, dont 90 % se trouvent en Afrique. Un total de 50 % des femmes infectees dans les zones d’endemie ont une atteinte genitale [1] . La localisation tubaire est rare et ses complications sont multiples. Observation Nous rapportons l’observation d’une schistosomiase tubaire bilaterale chez une femme nullipare de 25 ans consultant a la maternite universitaire Souissi de Rabat, pour une douleur pelvienne associee a une irregularite du cycle menstruel. Cliniquement, une masse pelvienne douloureuse est reperee. A l’imagerie, l’aspect est non specifique. La patiente a beneficie d’une salpingectomie bilaterale avec des suites operatoires simples. A l’examen macroscopique de la piece operatoire, les trompes sont tortueuses avec la presence d’un materiel necrotique friable en surface. L’etude microscopique a permis d’orienter le diagnostic par la mise en evidence d’une salpingite granulomateuse epithelioide et gigantocellulaires ou les cellules geantes renferment des formations calcifiees ayant l’aspect des œufs de bilharzie. Discussion Le developpement des oeufs de bilharzie au sein de la trompe peut etre responsable d’une sterilite ou d’une grossesse extra uterine [2] . Le diagnostic anatomopathologique est fait devant une reaction inflammatoire typiquement granulomateuse riche en cellules geantes multinuclees. Le diagnostic differentiel se pose avec les autres salpingites granulomateuses et notamment la tuberculose, l’oxyurose et la candidose.

Pleural fibroma, or fibrous tumor of the pleura, is an uncommon entity which is characterized by slow proliferation of undifferentiated, intermediary or mature fibroblasts associated with collagen fibers forming a tumor stroma. We report a case in a 49-Year-old man who developed exercise-induced dyspnea and right chest pain. The thoracic CT scan revealed the presence of a mass in the right lung base composed of heterogeneous encapsulated tIssue. Tumor resection was performed leading to the histological diagnosis of pleural fibroma. Immunohistochemistry tests revealed positive vimetin and CD34, and negative cytokeratin uptake. These immunohistochemistry data contributed to the differential diagnosis with malignant pleural mesothelium. Pleural fibroma is a benign tumor in 80% of the cases. Prognosis is excellent. Local recurrence is exceptional and generally occurs after incomplete resection. Radial surgical treatment determines the prognosis and is required to prevent local recurrence. Other criteria of malignancy are not correlated with the clinical course of this type of tumor.

Le teratome intrarenal est une tumeur extremement rare. Peu de cas ont ete publies dans la litterature medicale. Dans sa localisation renale, le diagnostic de teratome est rarement evoque en preoperatoire. Ses signes cliniques et radiologiques etant peu specifiques, le diagnostic final est souvent confirme par l’etude anatomopathologique. Nous rapportons le cas d’un teratome kystique de localisation intrarenal chez un nourrisson de cinq mois. Une exerese radicale de sa tumeur intrarenale a ete realisee. Devant la suspicion de tumeur de Wilms renale, une chimiotherapie etait administree en preoperatoire. La chirurgie est le traitement de choix du teratome intrarenal. Il n’est en general pas sensible a la chimiotherapie. Cela est du au caractere mature et bien differencie des tissus tumoraux qui le constituent. Pour le chirurgien et le pathologiste pediatres, ce diagnostic doit toujours etre present a l’esprit devant une masse renale kystique pour eviter une chimiotherapie nocive pour ces jeunes patients.

We report on a rare case of botryoid Wilms tumor extending into the duodenum. This uncommon macroscopic form of nephroblastoma consists entirely of a polypoid renal intrapelvic mass. The main differential diagnosis of this unusual tumor is botryoid rhabdomyosarcoma. A 14-month-old boy presented with a painful abdominal mass. Radiology revealed a large heterogeneous mass in the renal calyx, protruding into the ureter. A right radical nephroureterectomy was carried out. The tumor was found to extend into the 2nd portion of the duodenum. The pathologic diagnosis was mixed type nephroblastoma, SIOP 2001 stage III. The patient was given a course of postoperative chemotherapy. No local recurrence or metastatic spread has been detected after 2 years. Only few such cases have been previously reported, some of them extending into the bladder. To our knowledge, botryoid nephroblastoma has not previously been described as extending into the digestive system.

Le chondrosarcome mesenchymateux extrasquelettique est une tumeur rare des parties molles distincte sur le plan clinique, histologique, immunohistochimique et evolutif. Nous rapportons l’observation d’un homme de 44 ans presentant un nodule cervical asymptomatique depuis plusieurs annees dont la taille aurait augmente il y a deux ans. Une premiere biopsie a ete realisee et a conclu au diagnostic errone de tumeur mixte des glandes salivaires. Une exerese chirurgicale de la lesion etait realisee, suivie par trois recidives locales. Apres la quatrieme recidive, l’examen histopathologique avec etude immunohistochimique permettait de porter le diagnostic de chondrosarcome mesenchymateux extrasquelettique. Une radiotherapie et une chimiotherapie adjuvantes ont ete delivrees. L’evolution etait marquee par la survenue de metastases cutanee et vertebrale.

Resume Introduction Les tumeurs primitives des grosses structures vasculaires (aorte, artere pulmonaire et veine cave inferieure) sont tres rares. Une classification anatomopathologique de ces differentes tumeurs a ete etablie en se fondant sur leur siege de developpement et leur aspect macroscopique. Elle distingue le sarcome intimal a point de depart intimal et les tumeurs intramurales prenant naissance de la media ou de l’adventice et correspondant a des leiomyosarcomes ou des fibrosarcomes. Les sarcomes de la veine cave inferieure sont generalement des leiomyosarcomes. Observation Un sarcome intimal de la veine cave inferieure a ete diagnostique chez une jeune patiente âgee de 17 ans. L’etude microscopique, aidee par l’immunohistochimie, a permis ce diagnostic et l’elimination un leiomyosarcome ou d’un angiosarcome, de meilleur pronostic que celui du sarcome intimal. Discussion Le sarcome intimal de la veine cave inferieure est exceptionnel. Son diagnostic pre-operatoire est difficile. Il s’agit d’une tumeur peu differenciee et de tres mauvais pronostic par rapport aux autres tumeurs primitives du systeme vasculaire. L’etude anatomopathologique et surtout immunohistochimique permet de faire le diagnostic positif.

Carcinosarcoma of skin is a biphasic tumor composed of intimately admixed malignant epithelial and mesenchymal components. Various terms have been used to designate these tumors (metaplastic carcinoma, pseudosarcoma, spindle cell carcinoma, etc.). However, the histogenetic conception has changed and carcinosarcoma is currently regarded as authentic sarcomatoid carcinoma.The authors report the case of a 32-year-old women initially presenting with a budding and ulcerating tumor at the site of an old cutaneous scar on the right leg. Histopathological and immunohistochemical evaluation led to a diagnosis of cutaneous carcinosarcoma. One month after treatment, the patient developed inguinal lymph node metastasis.Our case and a review of other cases in the literature confirm the dual epithelial and sarcomatous phenotype of sarcomatoid carcinoma. Progressive transition between the cells of the two components on microscopic analysis and their positive immunostaining for anti-p53 antibody suggest a clonal origin of the tumor. The carcinomatous component seems to influence the course of the disease with the development of metastases, particularly at the lymph nodes. It thus seems advisable to combine lymphadenectomy with surgical tumor excision.

Uterine carcinosarcoma (malignant mixed mullerian tumor) is uncommon. We report the case of a 17-year-old patient who complained of pelvic pain and abnormal genital bleeding, and had a voluminous hemorrhagic tumor protruding through the vaginal os. Hysterectomy was performed. The histopathologic and immunohistochemical evaluation led to the diagnosis of uterine carcinosarcoma. Adjuvant chemotherapy was given. In spite of the surgical treatment, the evolution was fatal with widespread metastases. From data of the literature, we discuss the diagnosis, histogenesis and treatment of this rare tumor.

Male ,Humans ,Bone Neoplasms ,Female ,Fibroma ,Child - Abstract
Chondromyxoid fibroma is a rare benign tumor that is typically found in the metaphyseal ends of long tubular bones, such as the tibia. The radiographic appearances are those of a single, lytic lesion with lobulated margins, septations, cortical expansion and a sclerotic rim. The classic histological feature of a chondromyxoid fibroma is stellate or spindle-shaped cells arranged in lobules in a myxoid or chondroid background. Two cases are presented here: 8, and 12-year-old patients, both with lesions in the proximal tibia. The first case showed an unusual feature: it was diaphyseal chondromyxoid fibroma. In the second case, the lesion was metaphyso-diaphyseal. The differential diagnosis includes chondroblastoma, myxoma, aneurysmal cyst as well as chondrosarcoma. A surgical conservative treatment with complete excision is recommended even in case of recurrence.

Amoeboma is an inflammatory mass of the colon. It is uncommon with most cases occurring in Latin America and South Africa. When amoeboma is the presenting symptom of amoebiasis, it poses the problem of differential diagnosis of colon cancer. This report describes the case of a 60-year-old patient who presented a painful mass in the left hypochondrium. Radiologic and endoscopic examinations depicted a ring-like stenosis of the transverse colon in association with a mesenteric reaction. The presumptive diagnosis was colon cancer and the patient was referred to the National Oncology Institute for surgical treatment. Histological examination of the surgical specimen after segmental colectomy confirmed diagnosis of intestinal amoeboma. The patient was treated medically using metronidazole. Since intestinal amoebiasis is common in our country, amoeboma must be considered as a rare but potential diagnosis in patients presenting masses of the colon. Differential diagnosis of carcinoma is necessary to avoid the risks associated with unnecessary surgery.

Tuberculosis of the gallbladder is rare, even in our country known for being an endemic area. The positive diagnosis depends on suspicion of tuberculosis, peroperative findings and histological examination. From a review of the literature, the physiopathology of this infection is discussed, emphasizing the role of lithiasis in the development of tuberculous lesions. The authors report a case of gallbladder tuberculosis in a female patient who presented with a clinical picture of chronic cholelithiasis. The diagnosis of gallbladder tuberculosis was reached only after surgery and proven by histopathology. In our case, the presence of stones associated with non specific inflammatory alterations and possibly low resistance against tubercle bacillus, is believed to have been of importance for the development of the tuberculous infection.

- Abstract
Epithelioid sarcoma (ES) is a rare soft tissue tumor that is commonly misdiagnosed. It is a mesenchymal tumor that shows both mesenchymal and epithelial features. It tends to occur in the distal upper extremity in children and young adults but may appear in any location and any age group. Less than 1% of ES involve the head and neck. Clinically, the tumor can be mistakenly confused with a benign lesion as it can mimic nonspecific ulcers or infected warts. Histologically, ES is characterized by a nodular architecture and epithelioid appearance of cells centered with necrosis, mimicking a granulomatous process. We present the clinical history of a 12-year-old male who presented with an ES of the pretragus with a brief review of the literature to raise awareness on this rare entity and to discuss the challenges in managing histopathological differential diagnosis in front of this unusual clinical presentation., Competing Interests: None declared., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2024.)

- Abstract
Familial Mediterranean fever (FMF) is an autosomal recessive disorder, particularly common in the Mediterranean area. Mutations in the MEVF gene cause it. AA Amyloidosis is the most severe complication of FMF leading to chronic renal failure. We describe a rare pediatric case of a phenotype I familial Mediterranean fever with V726A heterozygous mutation. The diagnosis was made at chronic kidney disease. We discuss through this case the importance of the early diagnosis of FMF heterozygous children which is not usually evident in some phenotypes. It will surely avoid fatal complications, inappropriate therapeutic approaches and higher healthcare costs., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Introduction and Importance: Breast pathology in adolescents is rare and predominantly benign, with abnormalities including congenital anomalies, infections, mastodynia, nipple discharge, and mostly benign breast masses. Fibroepithelial tumors, the most common type, form a heterogeneous group that includes benign, borderline, and malignant entities such as phyllodes tumors. Differentiation of these tumors, especially various types of fibroadenomas, requires histopathological examination due to their similar radiological appearances and lesion heterogeneity. Recognizing the nature of these lesions is crucial to avoid missing malignant forms with metastatic potential. Giant juvenile fibroadenoma is a quite rare benign fibroepithelial tumour, that cannot be differentiate from phyllodes tumors before anatomopathological examination., Case Report: We report the case of a 14-year-old patient who presented with a rapidly enlarging mass in the left breast, and the diagnosis of giant juvenile adenofibroma was confirmed after surgical treatment., Clinical Discussion: Giant juvenile fibroadenomas occurs in adolescent girl and constitutes 0.5 % - 4 % of all fibroadenomas cases. When it exceeds 5 cm, weighs more than 500 g, or occupies more than 4/5 of the breast, it is considered as giant. It is characterized by a rapid increase in size, causing distortion and compression of the breast. Breast ultrasound is the first imaging modality, showing a large, well-limited hypo or iso echoic mass. The main differential diagnosis should be made with phyllodes tumors. The diagnosis is considered based on clinical and radiological features but is confirmed only after surgical excision of the mass and histological study., Conclusion: The discovery of a breast mass in an adolescent should prompt further investigations to avoid overlooking a fibroepithelial tumour. The most probable diagnoses are giant juvenile fibroadenoma and phyllodes tumors., Competing Interests: Conflict of interest statement The authors declare that they have no competing interests relevant to the content of this article., (Copyright © 2024 The Authors.

- Abstract
Introduction: Lipoma is the most common benign tumor of adipose tissue. Giant lipoma of the breast is defined as lesions larger than 10 cm and weighing more than 1000 g. A breast lipoma rapidly enlarging and fast growing; can be managed as a malignant tumor. It is crucial to make a correct diagnosis to prevent an overtreatment., Case Presentation: A 48-year-old patient presented with a painless, huge rapidly growing tumor in her right breast. Physical examination and imaging studies was suggestive of benign lipomatous breast tumor: A breast lipoma, a fibroadenolipoma or adenolipoma, an angiolipoma, or a breast fatty hamartoma. The patient underwent surgical excision of the mass, and histological examination confirmed the diagnosis of a giant breast lipoma., Discussion: Giant breast lipoma is a rare benign tumor that develops in the breast tissue. They can mimic various breast conditions, even neoplastic conditions. Giant breast lipomas are often treated with surgical excision to avoid recurrence., Conclusion: Giant breast lipoma rapidly growing can pose a diagnostic challenge due to its resemblance to various benign or malignant pathologies. Unnecessary invasive investigations can be avoided with better understanding and improved imaging-based diagnosis of giant breast lipoma., Competing Interests: Conflict of interest statement The authors declare that they have no competing interests relevant to the content of this article., (Copyright © 2024 The Authors.

- Abstract
Ewing sarcoma is a very rare tumour with aggressive behaviour and a poor prognosis. It tends to metastasize rapidly. Renal Ewing sarcoma is extremely rare, and only 48 cases have been reported in the literature. Herein, we report the case of a 14-year-old female presenting with a painful left flank swelling. Ultrasound and magnetic resonance imaging showed a large tumour invading the left kidney, heterogeneously enhanced after injection, associated with lymph nodes and peritoneal carcinomatosis. A thoraco-abdomino-pelvic computed tomography scan revealed pulmonary nodules and osteolytic lesions. A biopsy was performed, and histology, immunohistochemistry, and molecular studies confirmed the diagnosis of retroperitoneal Ewing sarcoma. Multi-agent chemotherapy followed by radical nephrectomy was performed, confirming the renal origin, and histology showed a post-therapeutical response. After a 1-year follow-up, there was no evidence of recurrence. We report this case to highlight the rarity of this entity and its challenging clinico-pathological diagnosis when presenting as a renal tumour., Competing Interests: None declared., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2024.)

- Abstract
Angiomyofibroblastoma (AMFB) represents a rare, benign mesenchymal tumor with a predilection for the vulvovaginal region. It is usually diagnosed in middle-aged women. Histopathology and immunohistochemical study remain the key to diagnosis. Like other benign mesenchymal vulval tumors, AMFB shows indolent behavior and rarely recurs after complete surgical excision. Herein, we present a case of vulvar AMFB in a 51-year-old woman to highlight the diagnostic difficulties when considering this rare entity., (© 2024 The Authors. Published by Elsevier B.V.)

- Abstract
Introduction: Uterine smooth muscle tumors of uncertain malignant potential (STUMP) are extremely rare, defined as a uterine smooth muscle tumors that cannot be diagnosed as benign or malignant and does not satisfy all the criteria for leiomyosarcoma or leiomyoma., Case Representation: A 48-year-old woman who presented with a history of heavy menstrual bleeding and pelvic pain. Physical examination revealed an enlarged uterus. Ultrasonography showed lobular and enlarged uterus containing multiples leiomyomas. A subtotal hysterectomy was performed. A Pathological analysis revealed a uterine mass diagnosed as a smooth muscle tumor of uncertain malignant., Discussion: Uterine STUMPs are rare and are commonly diagnosed by histopathological evaluation following myomectomy or hysterectomy. The most common clinical manifestations of uterine STUMP are the same as leiomyomas. Prognosis for the patient is unclear and there is a risk of recurrence with the tumors. However, considering their potential risk of recurrence and metastasis, it is advisable to maintain six-monthly controls for 5 years and then annual controls for 5 years more., Conclusion: Due to the rarity of uterine STUMP, there are no specific guidelines for their treatment and control. The scientific literature needs to be constantly updated in order to identify masses suspected of malignancy before surgery and improve patient management and follow-up., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests relevant to the content of this article., (Copyright © 2024 The Authors.

- Abstract
Uterine lipoleiomyomas are rare variants of uterine leiomyomas which is composed of adipocytes and smooth muscle cells. In this report, we describe the case of a 39-year-old patient who presented with persistent, isolated pelvic pain. Ultrasonography showed an oval, well-defined left ovarian mass. Computed tomography (CT) scanning showed a predominantly-fatty mass with tissular components, no calcifications and heterogeneously enhanced after injection, suggesting initially a mature teratoma. Magnetic resonance imaging (MRI) findings revealed a latero-uterine mass, suggesting the presence of a left ovarian dermoid cyst with a potentially-malignant fleshy component. A subsequent pathology report revealed a lipoleiomyoma with cartilaginous metaplasia. Most notably, despite the fatty nature of the tumour and the use of MRI, the pedunculated appearance of the lipoleiomyoma observed intraoperatively mimicked a dermoid tumour even on imaging. Improved understanding of leiomyoma variants and secondary degenerative changes can help prevent misdiagnosis., Competing Interests: None declared., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2024.)

- Abstract
Objective: To investigate the Pinus halepensis extracts and determine its healing and antibacterial effects, and to evaluate the treatment of skin burns., Methods: Aqueous and ethanolic extracts and topical based on Aleppo pine plant extracts were prepared. Thirty male and female Wistar rats were used to study the cutaneous toxicity of extracts from the bark of P. halepensis . The extracts' healing potential for burn wounds were also assessed by evaluating the clinical and macroscopic aspects of the wounds. The antibacterial activity of crude extracts of P. halepensis as well as its wound healing abilities was verified in this investigation., Results: In animals with acute dermal toxicity, there were no signs of treatment-related toxicity or death. The extracts of these plants could be transformed into phytomedicines for the treatment of infected wounds. The results demonstrated that formulated ointments are successful in treating second-degree burns in rats and may be suitable for the short-term therapeutic treatment of second-degree burns., Conclusion: This study successfully answered our problem, regarding the efficacy of our extract for treating second-degree burns in rats. Further studies are needed to confirm these results by identifying the molecules responsible for these activities and examining their mechanism of action., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Clear cell sarcoma of the kidney is the most frequently misdiagnosed renal tumor in children. We report the case of a 6-year-old boy with clear cell sarcoma of the kidney with an unusual presentation, including a primary tumor of the left kidney with metastasis in the homolateral psoas muscle. The renal tumor was revealed by abdominal mass without hematuria. In a review of the literature. Clear cell sarcoma of the kidney is most commonly associated with bone and lung metastases. Muscular metastasis at initial diagnosis has not previously been reported. This case represents an unusual metastatic pattern of clear cell sarcoma of the kidney. This also illustrates clear cell sarcoma of the kidney's ability to metastasize to other sites including the muscular. These tumors present a diagnostic challenge for the radiologist who should be aware of this entity to differentiate it from other renal tumors which are more frequent at this age. We aim to report the clinical, radiological features, and pathological presentation of this entity., (© 2023 The Authors. Published by Elsevier Inc. on behalf of University of Washington.)

- Abstract
Cynara humilis is traditionally used to treat skin burns and microbial infections. However, experimental studies on this plant are rare. Furthermore, the aim of this study was to investigate the effects of Cynara humilis , a Moroccan herbal remedy, on the healing of deep second-degree burns in rats with a silver sulfadiazine group. This research was also carried out to confirm if C. humilis had antibacterial capabilities. Under typical burn procedures, each rat received a deep second-degree burn on the upper back. The burns were treated regularly with control groups (control and control VH), silver sulfadiazine (SDD) in group 3, C. humilis ethanolic extract (CHEE) in group 4, and C. humilis aqueous extract (CHAE) in group 5. Throughout the treatment, digital photography was used to measure rat responses to the treatment until day 18. After the scar biopsy at the end of the study, histological parameters (inflammatory cells, collagen, epithelialization, fibrosis, and granulation tissue) were assessed. Using the well technique, the antibacterial activity of the extracts was tested against Staphylococcus aureus CIP 483, Bacillus subtilis CIP 5262, Escherichia coli CIP 53126, Pseudomonas aeruginosa CIP 82118, and Salmonella enterica CIP 8039, and the results showed important activities of the ethanolic and aqueous extracts against the five species tested with MICs of 2 and 4 mg/mL, respectively. In the aqueous extract group, the wound healed faster. In addition, the healing rate in the C. humilis extracts (CHEA and CHEE) group was faster than in the silver sulfadiazine and control groups. In the C. humilis group, maximum wound surface recovery was observed at the same time, as it was not noted in the silver sulfadiazine group. Pathologically, epithelialization was more marked in wounds treated with C. humilis extracts (CHE). Angiogenesis and inflammatory cells were considerably lower in the CHE group than in the silver and other control groups. However, elastic fibers were considerable in the CHE-treated group. In histological examination, the C. humilis group had a low incidence of angiogenesis and inflammation, indicating that this group had less wound scarring. Collagen and burn wound healing were both faster in the C. humilis group. The findings of this study suggest that C. humilis , as indicated by traditional medicine, is a promising natural source for the management of wound healing., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Najoua Salhi et al.)

- Abstract
Primitive myxoid mesenchymal tumor of infancy (PMMTI) is an extremely rare soft tissue tumor with only a few cases. Herein, we report a case of 5-months-old girl presenting with a soft tissue mass on the sole of the left foot that recurred 2months after a first resection. The Doppler ultrasound imaging showed abundant blood flow in the tumor. Magnetic resonance imaging (MRI) showed a well demarcated tumor on the sole of the left foot. The surgically resected tumor consisted of primitive mesenchymal tumor cells dispersed in a myxoid background with delicate small blood vessels. Immunohistochemically, tumor cells expressed vimentin but were negative for AE1/AE3, Desmin, Muscle-Specific Actin, MyoD1, Myogenin, CD34, S-100 protein and CD99. Fluorescence in situ hybridization (FISH) showed absence of chromosomal translocation involving SYT and ETV6. Thus, the patient was diagnosed with a primitive myxoid mesenchymal tumor of infancy. To our knowledge, this is the first case of PMMTI affecting the sole of the foot., (Copyright © 2021 Elsevier Masson SAS. All rights reserved.)

- Abstract
The present study aimed to evaluate the acute and subacute toxicity profiles of Erodium guttatum extracts in mice using the methods described in the guidelines of the OECD. In the acute toxicity study, the LD
50 value was greater than 2000 mg/kg. The subacute toxicity study of E. guttatum extracts showed no significant changes in body or organ weights. The administration of E. guttatum extracts to mice at a dose of 200 mg/kg led to an increase in white blood cells, platelets and hemoglobin. Moreover, the aqueous extract of E. guttatum only decreased liver aspartate aminotransferase (ASAT) levels at a dose of 200 mg/kg, and creatinine and urea levels did not show any significant alterations compared to the control group. Our results showed that the extracts of E. guttatum caused a slight increase in alanine aminotransferase (ALAT) and triglycerides. The histological study showed that mice treated with E. guttatum extracts experienced some histopathological changes in the liver, particularly with the methanolic extract, and slight changes in the kidneys and pancreas. Regarding the renal profile, no toxicity was observed. These results provide basic information on the toxicological profile of E. guttatum used in traditional medicine.- Published

- Abstract
Non-Hodgkin lymphoma (NHL) are common malignancies in children. Available data on clinico-pathological aspects of pediatric NHL in developping countries are limited and diagnostic approach appears more delicate with absence of molecular studies. The objectives of our study are: analyzing the pathological spectrum of NHL among children and highlighting challenges in the diagnosis including: limited biopsic material; unususal subtyptes, age group, or localization. We retrospectively analyzed clinico pathological characteristics of 101 NHL's cases among children diagnosed in the Pediatric's pathology unit over a period of 4 years There were 78 (77.2%) male and 23 (22.8%) female. The median age was 7.2 years. The most common histologic subtypes of NHL were Burkitt lymphoma in 65 patients (64.4% ); followed by lymphoblastic lymphoma in 22 patients, large B-cell lymphoma in 9 patients ( 8.9%); anaplastic T cell lymphoma in 3 patients; NOS mature T cell lymphoma and pediatric type follicular lympoma in 1 patient each. In conclusion, this study Morocco illustrates the pattern of distribution of NHL and emphasizes challenges in the diagnosis of these neoplasms., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

- Abstract
Background: Wound healing is among the frequent illnesses that affects the skin, and therefore, the screening of natural preparation to treat skin burn is important. In Morocco, Cynara humilis is a Moroccan medicinal plant widely used for the treatment of skin burn., Objectives: The aim of this study was to investigate the safety of C. humilis and its wound healing potential against skin burn., Methods: In this work, C. humilis was selected based on an ethnopharmacological survey. As revealed by traditional medicine, C. humilis powder extract (CHPE) was used to test wound healing effects. Furthermore, to assure the safety of this powder, acute and subchronic dermal toxicities were investigated on animal models., Results: The oral acute toxicity test of CHPE did not show mortality in treated rats (LD
50 >2000 mg/kg). Moreover, in the acute dermal toxicity, CHPE at 5 g/kg did not induce clinical signs observed during the observation period of 48 h. In the subchronic toxicity test, CHPE did not cause significant abnormalities in the physiological parameters and pathological changes in the major organs of the rats. Body weight evolution and macroscopic analysis of skin burn showed CHPE exhibited important wound healing effects in a time-dependent manner. CHPE reduced significantly wound surface (6.93 ± 0.25 cm2 ) compared with the SDA group (8.30 ± 0.37 cm2 ) and the no-treated group (10.05 ± 0.28 cm2 ). Moreover, the retention rate was increased importantly after the treatment with CHPE (61.66 ± 1.42%) compared with the SDA-treated group (53.57% ± 2.83%) and the no-treated group control animals (43.34% ± 1.27%)., Conclusion: These results were confirmed by a histological evaluation, which showed that CHPE increased the neovascularization, the collagen deposition, and the re-epithelialization. The findings of this work suggest that CHPE could be a promising source for developing drugs against skin burn., (© 2021 Wiley Periodicals LLC.)- Published

- Abstract
Osteosarcoma (OS) is the most common primary non hematopoietic malignant tumor of bone with a strict histologic definition: the presence of unequivocal osteoid produced by neoplastic cells. Rare variants displaying low-grade histological features have been described; among which chondromyxoid fibroma-like (CMF-OS) is the rarest. However, despite its bland morphology; CMF-like OS has an aggressive clinical behavior and a poor prognosis. To the best of our knowledge, only 3 cases of CMF-OS have been previously reported in children. Because of its atypicality and scarcity; misdiagnosis is more likely to occur. Herein we describe a new case of CMF-OS in a 13 years old girl with fatal outcome. Diagnosis was based on focal malignant bone formation and correlation with imaging studies. The aim of the present case presentation is to raise awareness of this rare entity and to highlight the challenging diagnosis., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

- Abstract
Background: Angiosarcoma of the breast is a rare tumor, which may be primary or secondary to breast surgery or irradiation. It is characterized by polymorphic and nonspecific clinical and radiological features. A pathologist plays a key role in positive and differential diagnosis and in establishing the prognosis: only a histological examination can confirm the diagnosis, and the histologic grade is the most important prognostic factor. In fact, angiosarcomas of the breast constitute a very heterogeneous group and they are classified into three grades based on the degree of differentiation. We will illustrate diagnostic challenges through this new case of primary angiosarcoma of the breast. Microscopic findings were initially interpreted as a benign vascular tumor. We will also discuss the relevant medical literature., Case Presentation: A 56-year-old Arabian woman presented with a palpable right breast mass that had been enlarging for 2 months, measuring 5 cm, without axillary lymphadenopathy. She had no personal or family history of breast surgery or breast irradiation. A mammography showed no evidence of spiculation. No suspicious calcifications were seen. A needle core biopsy was performed. Microscopic findings were initially interpreted as a benign vascular tumor. However, as the mass measured 5 cm, the diagnosis of angiosarcoma was more appropriate, and mastectomy without axillary dissection was performed. Microscopic examination found mild to moderately scattered pleomorphic cells, and scattered mitotic figures. It also showed papillary formations, solid foci of spindle cells, and hemorrhagic necrosis. The margins of the tumor were infiltrative. The diagnosis of primary intermediately differentiated angiosarcoma of the breast (grade II) was made. No distant metastases were found. Our patient was lost to follow-up and further treatment after mastectomy until she developed local tumor progression 4 months later., Conclusions: Through this case report, we emphasize the importance of clinicopathological confrontation in angiosarcoma of the breast.

- Abstract
Primitive intracardiac tumours are rare, especially in childhood, and are often discovered on autopsy. The intracardiac teratoma is the rarest intracardiac tumours of childhood. Herein, we report the case of an 11-month-old infant, which featured recurrent bronchoalveolitis since the age of 3 months, with a thoracic deformation. Physical examination did found discrete respiratory distress signs. Chest radiography showed large mediastinal enlargement. The computed tomography showed a solid cystic-cloisonned mass with fat and central calcification highly suggestive of an intracardiac teratoma. A radical surgical excision was made and the histological examination found a well circumscribed tumour containing elements of the three germ layers confirming the diagnosis of mature well-differentiated teratoma, with no need of immunohistochemical support.

- Abstract
Background: Peripheral primitive neuroectodermal tumors are extremely rare tumors in the spine; only 18 cases of extra-dural peripheral primitive neuroectodermal tumor cervical region have been reported. The aim of this report is to highlight the challenges in diagnosis and management of this condition., Case Presentation: We present a case of 5-year-old Moroccan boy, who presented with torticollis for 1 month. Computed tomography scan and Magnetic resonance imaging of the cervical spine revealed an extradural, dumbbell-shaped mass with extra-spinal extension at the left C1-C6 level. Multiple biopsy specimens were obtained. Histological examination revealed a highly cellular neoplasm composed of diffuse sheets of tumor cells having monomorphic, round to oval, finely vesicular nuclei. Immunohistochemical findings confirmed the diagnosis of intraspinal peripheral primitive neuroectodermal tumor., Conclusion: After this illustrative case, we review the literature on clinicopathological and therapeutic aspects. In practice, it is important to consider the diagnosis of peripheral primitive neuroectodermal tumor in children and adolescents with an apparent soft-tissue mass located in the spine.
