Background and Aim: Blood transfusions can be a crucial, life-saving treatment in modern medical and surgical practice. The primary objective of blood transfusion services worldwide is to guarantee the availability of a sufficient and safe supply of blood and blood products. Meticulous donor screening and use of highly sensitive techniques for the detection of transfusion-transmitted infections (TTIs) may help reduce the risk of TTIs and, hence, are important steps to ensure safety for both donor and recipient. Materials and Methods: This is a retrospective record-based study done at Hamdard Institute of Medical Sciences and Research. The blood donors' data from January 2012 to December 2022 (10 years) were collected from the blood bank registry at the study site and were analyzed. Results: Males dominated the donor population (98.2%) with females comprising only (1.8%). In total, 10.9% were found unfit for donation for various reasons. Voluntary donors were (6.3%) and replacement donors were (93.7%). Out of the reasons for deferral, majority 497/1223 (40.6%) donors were deferred due to hemoglobin <12.5 g/dl, followed by 156/1223 (12.8%) deferrals due to alcohol intake within the past 72 h. Conclusion: Safe donor selection is the first step toward safe transfusion services. Identification of population groups that can be targeted to enhance the pool of willing blood donors is made easier by studying and analyzing the blood donor profile. [ABSTRACT FROM AUTHOR]

Background and Aim: Head-and-neck cancers (HNCs) are significant causes of morbidity and mortality in both the developed and developing worlds. One of the most common types of HNC is oral squamous cell carcinoma (OSCC). The rationale behind the present study is to analyze the effectiveness of nuclear proliferative markers in comparison to the various grades of OSCC. This study utilizes Anneroth's histopathological multifactorial grading system for squamous cell carcinoma and further tends to compare this histological grading with nuclear proliferative indices of p53 and argyrophilic nucleolar organizer region (AgNOR). The aim of this study was to establish and develop a correlation between the proliferative markers, AgNOR and p53, and the histologic grade of the tumor (Anneroth's grading). Materials and Methods: A total of 60 cases of oral squamous cell carcinoma were taken from October 2020 to September 2022. The histological grading was done according to Anneroth's grading, and a score was given. P53 expression was graded according to the percentage of cells showing p53-positive immunostaining, and scoring was done from 0 to 3. The AgNOR score was calculated by examining 100 nuclei and calculating the mean AgNOR score per nucleus. Results: A significant linear correlation was obtained between the histological grading of OSCC and the proliferative markers (p53 and AgNOR). Conclusion: The analysis of the NOR count provides invaluable assistance in determining tumor aggressiveness and cellular proliferation rates. They can prove to be efficient tools to procure information on the malignant potential of different premalignant lesions. Elevated p53 expression implies greater clinical severity, a higher histological grade, and a poor prognosis for oral squamous cell carcinoma. Hence, the proliferative markers can be used as adjuncts to the histological grading system of OSCC. [ABSTRACT FROM AUTHOR]

Primary uterine diverticula are a very rare congenital anomaly of the uterus with only 21 reported cases. Even rarer is the occurrence of primary cervical diverticula with only six cases reported so far. This is a unique case of a huge abdominopelvic mass arising from cervical fibroid around an infected cervical diverticulum. A 44 year-old, P4L4 came to the OPD with a eighteen weeks size abdomino-pelvic mass. She had a failed surgery 6 months back, attempted to remove the mass. Magnetic resonance imaging revealed a cervical diverticulum which possibly had a pus collection. Relaparotomy was done. It revealed a huge cervical fibroid with dense adhesions all around the mass. A pan hysterectomy was done. In the postoperative period, she developed high-grade fever owing to the development of a pelvic collection, which had to be drained by dilating the vault sutures. Histopathology report confirmed a cervical fibroid with an infected diverticulum within. Primary uterine or cervical diverticula are a very rare anamoly which possibly arise because of a weakness in the area where the two mullerian ducts fuse. Women with this rare condition may suffer from infertility, fever and pain abdomen, acute abdomen owing to torsion or hemoperitoneum, pregnancy complications, and menorrhagia. Diverticulectomy and cervical/uterine reconstruction can be done on nulliparous women while hysterectomy can be offered to perimenopausal women. To conclude, unless known by the gynecologists, radiologists, and the pathologists, this diagnosis can be easily missed out, leading to multiple preventable complications. [ABSTRACT FROM AUTHOR]

Ependymoma has been typically described as an intramedullary tumor which is derived from ependymal cells. Intradural extramedullary spinal ependymomas are extremely rare. Hereby, we present a case report of a patient was diagnosed with an intradural extramedullary spinal tumor extending from D8-D9 level. Patient underwent gross total resection of the tumor. The tumour was diagnosed as a collision tumor, ie Ependymoma with Schwannoma like areas on histopathological examination, later confirmed by immunohistochemistry. [ABSTRACT FROM AUTHOR]

Endometriosis is a prevalent benign condition arising from the female reproductive system and affects about 7%–10% of females. The association of endometriosis with serous borderline ovarian tumors has been a matter of interest in gynecology. Sampson first described the association between endometriosis and carcinoma. The endometriosis-associated ovarian malignancies are clear cell adenocarcinoma and endometrioid adenocarcinoma, whereas serous and mucinous are rare malignancies associated with endometriosis. Here, we present the case report of a 45-year-old female in which endometriosis was associated with borderline serous tumor, since there is a lack of enough confident criteria for diagnosing endometriosis-associated ovarian tumors.

Background and Objectives: Oral verrucous hyperplasia and verrucous carcinoma are two clinicopathologically distinctive oral verrucous lesions, current understanding of these lesions is perplexing hence it is important to investigate the clinicopathological features of the two verrucous lesions and estimate their relationship. The present study was undertaken with the aim of identifying the pathological features in an attempt to differentiate both lesions. Materials and Methods: Archives of the department were retrieved for verrucous lesions. 20 cases were included in the study. Each patient was reviewed for clinical details like age, sex, habits, clinical features like site of lesion, clinical diagnosis, presence of associated lesions. Pathological details including both gross and microscopic features were analyzed. Results: A total of 20 patients included in the study showed a male preponderance with a significant association with tobacco consumption and size of lesion. Majority of the lesions were localized to the buccal mucosa, histopathological features were characteristic of each lesion. Expression of Ki-67, a proliferative marker showed, a statistically significant association between the mean LI of both the lesions. Conclusions: VH and VC are closely related lesions difficult to clinically differentiate, hence histopathological evaluation plays a pivotal role in establishing a diagnosis. Differentiating the two is essential and it should be kept in mind that VH may transform into VC hence, acting as a potential precancerous lesion. [ABSTRACT FROM AUTHOR]

BACKGROUND : The histological response to chemotherapy is regarded as an independent prognostic variable in bone tumours. The surgical pathologist, thus has an important role in the management of primary malignant bone tumors like osteosarcomas and Ewing′s sarcoma subsequent to neoadjuvant chemotherapy. AIMS AND OBJECTIVES: We report a short series of fifteen cases of osteosarcoma and three cases of Ewing′s sarcoma in which the histological response of the tumor after giving neoadjuvant chemotherapy to the patient of bone tumours was assessed and graded. MATERIAL AND METHODS: Bone tumours was assessed and graded by Huvos grading. The correlation of this histopathologic tumor response with clinical outcome is a well-established routine investigation in patients with bone sarcomas and the grading of the tumor response is based on definable histopathologic criteria. RESULT: Fifteen out of eighteen cases in this study showed a response to neoadjuvant chemotherapy, which was categorized as Huvos Grade 1 (%50%) and Huvos Grade 2 (50% to 90%). One case of osteosarcoma showed a Grade 4 response with a total absence of tumor cells in all the sections. One case of osteosarcoma and Ewing′s sarcoma each were categorized as Grade 3, showing tumor foci. CONCLUSION: It was concluded that necrosis of tumor area when greater than 90%, is regarded as a powerful positive prognostic indicator for survival in patients of high grade bone sarcomas.

Introduction: Early detection of oral cancer is one of the most efficient ways to reduce the high mortality from this disease because of the ready accessibility of the oral cavity. We need to devise urgent diagnostic tools to detect early oral premalignant and malignant lesions. Aim: The aim of the present study was to grade the oral lesions in an attempt toward developing a novel cytological grading system. Further, morphometric analysis of cellular parameters was also performed to compare their significance in differentiating benign from malignant lesions. Materials and Methods: The present study was conducted at a tertiary care hospital catering to the low socioeconomic population. Patients presenting in the various Out Patient Departments with suspicious oral lesions were evaluated by cytology in the Department of Pathology. Results: A total of 72 patients were evaluated with a mean age of 43.54 ± 10.35 years. The involvement of the buccal mucosa was the most common site of oral lesions. Cytologically, the lesions were graded according to the oral/oro-pharyngeal cytology grading system into grades A to F. Cyto-morphometric analysis showed an increasing trend in mean nuclear diameter from benign to malignant cases while the mean cytoplasmic diameter decreased, value of P < 0.05 was observed indicating a statistically significant difference between the two groups. Conclusions: Cytological features of pleomorphism are a unique feature in oral carcinoma reflecting intracellular alterations in cells. Grading of lesions according to cytological characteristics can be helpful in standardizing the reporting of the oral lesion. However, our study was restricted by limited data; we emphasize more extensive studies to assess the usefulness and applicability of such a grading system. We also conclude that the use of cytomorphometry can improve the diagnostic reliability of exfoliative cytology. [ABSTRACT FROM AUTHOR]

Background: Amyloidosis is characterized by the deposition of polymeric fibrillar proteins in the extracellular compartment in tissues and organs ultimately leading to damage with functional compromise. Cutaneous amyloidosis is clinically classified into more common macular, papular and the rarer nodular form. The present study was undertaken with the aim to histopathologically analyze and characterize clinically diagnosed amyloid cases. Methods:The present study was a retrospective analysis of skin biopsies conducted over a one year period. Data on the age and presenting clinical features were retrieved from the accompanying laboratory request forms or patients records wherever available. All skin biopsies with a histologic diagnosis of amyloid were retrieved and reviewed, the pattern of amyloid deposition identified and classified. Special stains including Congo Red stain was done in all the cases. Results: Histopathological confirmation of cutaneous amyloidosis was seen in nine out of fourteen cases and was confirmed by positive Congo-red stain under polarized light. Out of this seven were females and two were males. Majority of the lesions were of macular type. In all the nine cases, family history was negative and no evidence of systemic involvement was noted, either clinically or based upon the lab investigations. Conclusions: In this pilot study of 9 cases, histologically diagnosed as cutaneous amyloidosis we noted a female preponderance in young and middle-aged persons. Macular amyloidosis was the most common form and the most common site of involvement, the upper extremity and the inter-scapular/back region. [ABSTRACT FROM AUTHOR]

Tuberculosis (TB) and malignancy are among the most important current global health problems. Many authors suggest that their coexistence is a chance association owing to their high prevalence. There is, however, enough evidence that one condition may predispose the other. In our retrospective report of two cases, TB in draining lymph nodes was discovered incidentally on histopathology, following surgical resection for malignancy. The possibility of coexistent lesions, especially in regions endemic for TB, mandate a detailed histopathological examination to prevent the chances of diagnostic failure and thus therapeutic error.

Heterotopic or ectopic tissue is a congenital anomaly, which is defined as the presence of the tissue outside its normal location, without neural, vascular, or anatomic connection with the main body of an organ in which it normally exists. This tissue is usually discovered incidentally and may be asymptomatic or may present with nonspecific gastrointestinal (GI) symptoms. Pancreatic and gastric heterotopia are the two predominantly occurring heterotopic tissues in the GI tract.[1],[2] The prevalence of ectopic pancreatic tissue in the GI tract ranges from 0.6% to 13.7% of autopsy series and it can be present anywhere in the GI tract with the most common localizations being stomach (27.5%), duodenum (25.5%), colon (15.9%), esophagus, and Meckel's diverticulum.[3],[4],[5] It is a rare finding in the gallbladder and its prevalence has not been ascertained due to lack of large-scale studies and systematic review of literature. Similarly, heterotopic gastric tissue is common throughout the GI tract from the tongue to the rectum,[6],[7] but it is extremely rare in the gallbladder with only around 34 cases reported in literature so far, while other cases of different types of heterotopic tissues in the gallbladder such as liver tissue and others such as adrenal and thyroid tissues have been described.[8] The most common presentation of ectopic tissue in the gallbladder is colicky pain in the epigastrium or right upper quadrant sometimes associated with nausea and vomiting. Here, we are presenting two incidentally detected cases, each of gastric and pancreatic heterotopias in the gallbladder. [ABSTRACT FROM AUTHOR]
