Neurofibroma of the scrotum is a very uncommon benign neoplasm, specifically when it affects teenagers and is not associated with neurofibromatosis type I. To the best of our knowledge, only a couple of cases of neurofibroma in children have been documented. Here, we report a case study of a 17-year-old boy who had a giant scrotal lump for ten years masquerading clinically as filariasis. A provisional diagnosis of benign nerve sheath neoplasm was made based on cytology findings. The lump was surgically removed from the patient, and a histopathological and immunohistochemistry examination established the diagnosis of neurofibroma. The combined clinical, preoperative cytological, histological, and immunohistochemistry findings were not presented in the literature in any of the formerly documented cases of scrotal neurofibroma. The current case expands the spectrum of differential diagnoses for scrotal tumours that clinicians have previously observed.

Introduction: Scrotal squamous cell carcinomas (SCCs) are rare malignancies that are not considered to be associated with the human papillomavirus (HPV) by the International Agency for Research on Cancer. However, recent studies have detected HPV in these cancers. We sought to determine the presence of HPV types among scrotal cancer cases identified through population-based cancer registries., Methods: Primary scrotal SCCs diagnosed from 2014 to 2015 were identified, and tissue sections from formalin-fixed, paraffin-embedded tissue blocks were obtained for laboratory testing. A pathology review was performed to confirm morphology. HPV testing was performed using L1 consensus polymerase chain reaction analysis. Immunohistochemistry was used to evaluate p16INK4a (p16) expression., Results: Five cases of scrotal SCC were identified from 1 cancer registry. Age at diagnosis ranged from 34 to 75 years (median, 56 years). Four cases were non-Hispanic White, and 1 was non-Hispanic Black. The morphologic subtype of 4 cases was keratinizing (usual), and 1 case was verrucous (warty) histologic subtype. Two of the usual cases of SCC were HPV-negative and p16-negative, and 2 were positive for HPV16 and p16. The verrucous (warty) SCC subtype case was HPV6-positive and p16-negative., Conclusions: The presence of HPV16 and p16 overexpression in the examined tissue specimens lends additional support for the role of HPV in the etiology of scrotal SCC., (© 2023 National Cancer Registrars Association.)

Objective: The term ''Human Papillomavirus'' or ''HPV'' has become synonymous with uterine cervical cancer leading to feminisation of all the preventive measures, especially immunisation. Taking into consideration the rising number of HPV associated cancers among men in many developed countries and the risk of transmission to women, male HPV infection is a serious concern. A systematic review and meta-analysis of literature was performed to determine the global prevalence of HPV among men with oropharyngeal and anogenital cancers., Methods: A systematic review and meta-analysis of literature was performed searching electronic databases for published articles in English between January 1984- April 2020 based on standard systematic review guidelines. The meta-analysis component was modified appropriately for the synthesis of prevalence study results. National Institutes of Health checklist for observational, cohort and cross-sectional studies was used to assess the quality of the studies selected after the abstract and content review. The meta-analysis was performed in STATA version 13.0 (College Station, Texas 77,845 USA) and the forest plots were constructed using metan package in STATA., Results: Through the electronic search of databases, 3486 original articles were screened for eligibility. Fifty-eight articles were systematically reviewed and 42 articles were qualified for meta-analysis including 4,250 men with oropharyngeal, penile and prostate cancers. The pooled prevalence of HPV DNA in oropharyngeal cancers was 45% (95%CI 24.0%-66.0%). Meanwhile the pooled prevalence rates of 48% (CI 40.0%- 57.0%) and 19% (CI 10.0%-29.0%) were observed in penile and prostate cancers respectively. Even though, articles regarding HPV prevalence in anal cancers were systematically reviewed, none of the studies were qualified for meta-analysis., Conclusion: Higher pooled prevalence of HPV DNA was observed among men with oropharyngeal and penile cancers. Multicentric molecular studies investigating the prevalence of HPV in prostate cancers have to be planned in future.

Mixed epithelial-stromal tumours (MESTs) of the seminal vesicle (SV) are a rare neoplasm, with biological behaviour ranging from benign to malignant. Due to their rarity, there are no established guidelines for their treatment. We report a 37-year-old man with a large MEST of the SV which was successfully resected by laparoscopic transperitoneal approach. Amidst the controversy regarding the nomenclature and grading of MESTs in literature, we reclassified the previous reports of MESTs incorporating both the WHO and Reikie et al grading., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Purpose: Liposarcomas found incidentally during open or laparoscopic inguinal hernia surgery are extremely rare. It is unclear, whether any adipose tissue being removed during inguinal hernia surgery must be sent for histology due to the potential risk of liposarcoma of the spermatic cord. This study aims to evaluate the frequency of liposarcomas incidentally found in the inguinal canal during hernia surgery and tries to derive evidence-based recommendations regarding the optimal management of any fatty tissue found in the inguinal canal. Methods: A literature review of the PubMed/Medline electronic databases between January 1980 and January 2019 was performed using the search terms 'inguinal hernia' and 'liposarcoma'. There was only one study available on this topic. Therefore, an additional literature review was performed analyzing all reports on patients with incidentally detected liposarcomas of the spermatic cord in the inguinal canal during hernia surgery. Results: There was only one retrospective study evaluating the frequency of inguinal liposarcoma found at hernia operations with a frequency of less than 0.1%. There were 18 cases of spermatic cord liposarcomas that were truly found incidentally during operation for an unsuspected symptomatic or incarcerated inguinal hernia. These included 16 case reports with a total of 18 patients and 19 liposarcomas. All patients were male with a median age of 62.5 years (range: 24-86 years) years. Median size of liposarcoma was 10.5 cm (range: 3-30 cm). In seven patients, the inguinal liposarcoma was an extension of a retroperitoneal sarcoma. Treatment consisted of radical orchidectomy during the primary operation in 12 patients. Three out of the seven patients with retroperitoneal extension of the tumor underwent a secondary operation with complete resection of the tumor. Conclusions: Currently, there is no evidence-based recommendation available regarding the management of lipomas detected during open or laparoscopic inguinal hernia surgery. Due to the extremely low risk of the presence of a liposarcoma, routine histologic examination cannot be recommended unless the diameter exceeds 10 cm.

Spermatic cord malignancies are very rare tumours. Less than 100 cases of cord liposarcoma have been reported in the literature. Divergent differentiation into leiomyosarcoma and liposarcoma is a rare phenomenon but can occur. Lipoleiomyosarcoma usually represents the well-differentiated subtype of this entity. We report such a rare case in spermatic cord with an unusual presentation as a recurrent inguinal hernia in a 62-year-old man., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

Background: Whether kidney transplant recipients who were treated for a malignant tumor before transplantation are at an increased risk of developing a tumor posttransplantation has not been adequately quantified and characterized., Methods: We studied more than 270 000 patients on whom pretransplant and posttransplant malignancy data were reported to the Collaborative Transplant Study. More than 4000 of these patients were treated for pretransplant malignancy. The posttransplant tumor incidence in these patients was compared to that in recipients without a pretransplant tumor. Cox regression, considering multiple confounders, was applied., Results: Significant increases in posttransplant tumor incidence with hazard ratio ranging from 2.10 to 5.47 (all P < 0.001) were observed for tumors in the site-specific pretransplant locations, suggesting tumor recurrences. There were also significantly increased de novo tumors in new locations with hazard ratio ranging from 1.28 to 1.89. Pretransplant basal cell carcinoma of the skin and male genital cancer were associated with significantly increased death-censored graft survival, suggesting impaired immune responsiveness against transplanted kidneys. Time interval from pretransplant tumor occurrence to transplantation and posttransplant mammalian target of rapamycin inhibitor treatment was not found to be of significant relevance in this study., Conclusions: Patients who experienced a pretransplant tumor are at significant risk of tumor recurrence, regardless of the length of interval between tumor treatment and transplantation. There is also some increased risk for de novo tumors, suggesting impaired immune surveillance. Impaired tumor immunity appears to extend to a lower rate of transplant rejection because patients with pretransplant tumors tended to show improved death-censored graft survival.

Papillary cystadenoma of the epididymis (PCE) is a rare benign epithelial tumor remarkable for its association with von Hippel-Lindau disease. A 12-year-old boy consulted for a progressive enlargement of the left testicle. At time of surgery, the whole epididymis was enlarged. Pathologic diagnosis was PCE with a focus on borderline malignancy. Scrotal left epididymectomy was performed. von Hippel-Lindau disease screening was negative. No relapse has been detected 2 years later. In case of atypical clinical examination of a hydrocele, unusual presentations such as PCE should be considered. The main differential diagnoses were adenomatoid tumor, nonpapillary cystadenoma, and metastatic clear cell renal carcinoma., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Epidermolytic hyperkeratosis presents a particular histological image common to several clinical pictures, including that of keratinopathic ichthyoses. It may also occur fortuitously in various tumoral and inflammatory lesions. It is the elementary histopathological lesion of epidermolytic acanthoma, which may either be single or multiple, and when it occurs in the genital area, is known as epidermolytic hyperkeratosis of the genitalia or multiple epidermolytic acanthoma of the genitalia. Herein, we report two characteristic cases of epidermolytic hyperkeratosis of the genitalia., Patients and Methods: The first patient was a 50-year-old woman consulting for vulvar pain in whom clinical examination revealed the presence of multiple papules on the labia majora and minora. The second patient was a 44-year-old man consulting for verrucous lesions of the scrotum. In both cases, biopsy revealed an histopathological aspect identical with acanthosis, hyperkeratosis, changes in the keratinocytes, in which the cytoplasm contained clear vacuoles, numerous keratohyalin granules and eosinophilic bodies, resulting in a diagnosis of epidermolytic hyperkeratosis of the genitalia., Discussion: Epidermolytic hyperkeratosis of the genitalia is a rare disease, occurring in middle-aged men and women, but chiefly men. The lesions found on the genital organs may be either single, or, more frequently, multiple, and are described as hyperkeratotic papules, which are also reported under the term multiple epidermolytic acanthomas of the genitalia. The aetiology is unknown; certain authors incriminate a traumatic factor; the role of human papillomavirus (HPV) has been suggested but immunohistochemical studies and molecular biology studies generally reveal no viral DNA. Where lesions cause discomfort to the patient, treatment consists of emollients combined with destruction by cryotherapy or CO2 laser. Imiquimod, calcipotriol, tacrolimus and pimecrolimus have all resulted in regression of lesions., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

The current case report describes a 35-year-old man who presented with unilateral scrotal angiomas. The presence of unilateral scrotal angiomas was associated with an underlying varicocele on the ipsilateral side due to increased venous pressure. In case of unilateral scrotal angiomas further examination for underlying pathology is necessary.

Pain perception is influenced by multiple factors. The single nucleotide polymorphisms (SNPs) of some genes were found associated with pain perception. This study aimed to examine the association of the genotypes of ABCB1 C3435T, OPRM1 A118G and COMT V108/158M (valine 108/158 methionine) with pain perception in cancer patients. We genotyped 146 cancer pain patients and 139 cancer patients without pain for ABCB1 C3435T (rs1045642), OPRM1 A118G (rs1799971) and COMT V108/158M (rs4680) by the fluorescent dye-terminator cycle sequencing method, and compared the genotype distribution between groups with different pain intensities by chi-square test and pain scores between groups with different genotypes by non-parametric test. The results showed that in these cancer patients, the frequency of variant T allele of ABCB1 C3435T was 40.5%; that of G allele of OPRM1 A118G was 38.5% and that of A allele of COMT V108/158M was 23.3%. No significant difference in the genotype distribution of ABCB1 C3435T (rs1045642) and OPRM1 A118G (rs1799971) was observed between cancer pain group and control group (P=0.364 and 0.578); however, significant difference occurred in the genotype distribution of COMT V108/158M (rs4680) between the two groups (P=0.001). And the difference could not be explained by any other confounding factors. Moreover, we found that the genotypes of COMT V108/158M and ABCB1 C3435T were associated with the intensities of pain in cancer patients. In conclusion, our results indicate that the SNPs of COMT V108/158M and ABCB1 C3435T significantly influence the pain perception in Chinese cancer patients.

Massive localized lymphedema (MLL) is an uncommon benign skin lesion typically presenting with prominent edema and vascular proliferation in the adipose tissue of lower limbs. When rarely occurring in scrotum, it instead is characterized by a striking proliferation of dermal smooth muscle bundles mimicking acquired smooth muscle hamartoma of dartos. The authors report a rare case of scrotal MLL. A 57-year-old obese man with a history of previous surgery for rectal adenocarcinoma, 20 years earlier, presented with progressive nodular enlargement of the scrotum for 2 years, causing discomfort, difficulty in ambulation, and cosmetic problems. The preoperative radiographic investigation revealed thickening of the scrotal wall with multiple soft-tissue nodules. The patient underwent a wide excision of the scrotal wall, perineum, and penile skin. The pathological examination showed a scrotal MLL associated with well-differentiated squamous cell carcinoma. The authors speculate that prior radiotherapy and surgery together with morbid obesity led to long-standing lymphedema that triggered the proliferation of smooth muscle cells, chronic epidermal change, and finally squamous cell carcinoma.

Reproductive dysfunction and malignancies related to the male gender represent a serious health concern, whose incidence has significantly risen over the past years. Prior to treatment, testicular or prostate cancer patients often display poor semen characteristics similar to subfertile or infertile patients. This fact is underscored by cases where the malignancy is often diagnosed in males who undergo a general fertility screening. This review aims to examine the associations between male infertility and reproductive cancers focusing on common etiologies and biological mechanisms underlining these pathologies. Furthermore, we discuss compelling epidemiological data hypothesizing that male reproductive failure may act as a precursor of future andrological malignancies, including testicular or prostate cancer, thus providing a stimulus for a more specific research in male reproductive health and emphasizing the importance of this relation for physicians taking care of male patients with a reproductive disease.

A 43 -year-old man was treated with pazopanib for metastatic renal cell carcinoma (RCC) with imaging studies suggesting a partial response to treatment. However, the patient presented numerous times with severe testicular pain and gradually increasing priapism. He underwent an inguinal orchidectomy for symptom control. Histopathology confirmed invasion of the cord and tunica vaginalis with metastatic RCC. Further CT of the abdomen and pelvis suggested non-progression of the disease. The patient continued to develop priapism for several weeks before imaging studies confirmed disease progression; a month later the patient died. Genital involvement in metastatic RCC is unusual but should alert clinicians to the possibility of disease progression., (2015 BMJ Publishing Group Ltd.)

A 46-year-old man presented to our hospital for further examination following a positive fecal occult blood test. He also had a painless, palpable scrotal mass that had been present for several years, but he had not previously sought treatment. Colonoscopy demonstrated multiple adenomatous polyps and colon cancer ; when taken together with his family history, these findings led to the diagnosis of familial adenomatous polyposis. A computed tomography scan revealed a right intrascrotal tumor, and the patient was referred to our department. Together with digestive surgeons, we carried out scrotal mass resection and colectomy under general anesthesia. On scrotal exploration, a large, solid mass was identified ; it was separate from the testis and epididymis. Although the mass was adhered to the surface of the corpus cavernosum penis, we were able to completely resect the mass along with part of the corpus cavernosum penis. The tumor was composed of abundant collagen fibers and mature fibroblasts. Histopathology revealed the right scrotal mass to be a desmoid tumor. The patient is alive with no evidence of disease 24 months after surgery.

Epidermolytic acanthoma is an uncommon benign tumor with a predilection for the anogenital region, that is characterized histologically by epidermolytic hyperkeratosis. Most reported cases are asymptomatic while some are pruritic. Treatment of this condition is challenging and not well studied. We report a 55-year-old man with pruritic anogenital epidermolytic acanthomas that persisted despite various topical and ablative therapies, and whose pruritus was not relieved with emollients and antihistamines. He was given 0.1% tacrolimus ointment twice daily and experienced a marked improvement in his pruritus within 2 weeks. At 1 month, there was marked improvement in itch score from 8 to 3.5 (maximum of 10), itch frequency from 20 times a day to once every 4 days, sleep score from 5 to 1 (maximum of 5), and Dermatology Life Quality Index score from 15 to 5 (maximum of 30). Apart from a transient burning sensation, no other adverse effects were noted. To our knowledge, this is the first report of the effective use of a topical calcineurin inhibitor in relieving the intractable itch associated with epidermolytic acanthoma., (© 2013 Wiley Periodicals, Inc.)

Background: Metastatic melanoma of the seminal vesicles is a very rare clinical entity and has been reported only once until today in a patient suffering from concomitant HIV infection 12 years ago., Case Presentation: We report a case of persistent, painless hemospermia in a young Caucasian caused by metastatic malignant melanoma of the right seminal vesicle. The diagnosis was established by magnetic resonance imaging and transrectal ultrasound-guided biopsy. In the subsequent diagnostic workup the primary location of the tumor remained unknown but concomitant pulmonary, hepatic and supraclavicular lymph node metastases have been detected. Despite immediate chemotherapy initiation the patient finally succumbed to his progressive disease six months later., Conclusions: Malignant melanoma should be considered as a rare differential diagnosis of hemospermia after common causes have been ruled out.

Incarcerated inguinal hernia is a common surgical indication in the emergency room. Delayed diagnosis can result in ischemic bowel or bowel perforation. The reported incarcerated contents include bowel loop, mesentery, omentum and, rarely, malignant lesions, such as lymphoma, metastatic tumors etc. We report a new case of primary spermatic cord liposarcoma presenting as emergent incarcerated inguinal hernia and review the related literature.

We report the first case of a patient with extratesticular Leydig cell tumor associated with congenital adrenal hyperplasia. An 18-year-old congenital adrenal hyperplasia patient presented with a palpable and asymptomatic right extratesticular mass. Color Doppler sonography confirmed the presence of a capsulated and vascularised lesion. Sieric tumor markers were negative. The patient underwent surgical scrotal exploration through an inguinal right incision. The mass, 18 mm in size and located within the spermatic cord, was removed and final pathology diagnosed a benign Leydig cell tumor., (© 2012 The Japanese Urological Association.)

Leiomyosarcoma of the scrotum is a rare tumor. We report the case of a 60-year-old man who presented with bilateral testicular enlargement that was clinically misdiagnosed as a testicular tumor. The tumor was excised by bilateral inguinal orchiectomy. Histopathologic examination revealed a scrotal wall leiomyosarcoma with bilateral epididymo-orchitis., (Copyright © 2011 Elsevier Inc.

A 52-yr-old man presented with severe obstructive urinary symptoms. Ten years earlier, a digital rectal examination disclosed a small mass above the prostate, and a computed tomography (CT) scan showed a 3.5-cm cystic tumor of the right seminal vesicle. He had been followed conservatively elsewhere. Reevaluation of the mass with a CT scan and magnetic resonance imaging showed that the mass had grown to a maximal diameter of 14 cm. A transabdominal needle biopsy revealed benign fibromuscular tissue. The tumor was then resected by an open transvesical approach. Pathology was consistent with a benign seminal vesicle cystadenoma. The natural history, pathology, and surgical approach are described., (Copyright © 2009 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

Introduction: Primary adenocarcinoma of the seminal vesicle is an extremely rare condition. Some cases have been described in relation to congenital seminal vesicle cysts, which is often also associated with agenesia or ipsilateral renal disgenesia. The rareness of this type of lesions makes it difficult to plan a regulated surgical approach for them, although they are often treated by simple exeresis or exenteration, depending on their stage at the beginning., Materials and Methods: We present a new surgical technique that consists of radical vesiculectomy associated with laparoscopic partial prostatectomy (total segmentary) of the central area to successfully treat primary seminal vesicle adenocarcinoma in a young man who was diagnosed through an azoospermia study., Results: A study of the scan (MRI) with diffusion and the transrectal biopsy of the mass allowed us to make a thorough preoperative evaluation of the case, confirming the malignity and precociousness of the lesion. The laparoscopic approach allowed us to perform a pelvic lymphadenectomy and transperitoneal exeresis, including the central prostate area and suture of the posterior face of the urethra at the height of the apex of the prostate. The wall of the seminal cyst lesion confirmed infiltrating clear cell adenocarcinoma and non-invasive adenocarcinoma in the prostate segment of the central gland in the light of the ejaculatory conduct with "in situ" growth. Thus, the surgical specimen allowed radical exeresis with negative margins, guaranteeing minimally invasive surgery with preservation of continence and erection., Conclusion: We describe a new integral approach for the radical surgery of localized primary adenocarcinoma of the seminal vesicle. Despite its exceptional nature, the case allowed for a double reflection: a) The study of diffusion with MRI may suggest the diagnosis of malignity in this type of lesions; and b) Radical surgical treatment must include exeresis of the central portion of the prostate gland., (Copyright © 2011 AEU.

Genital and perianal ulcers seen in patients with HIV are commonly due to herpes simplex virus (HSV) infection. While it is well known that the characteristic presentation of HSV is a vesicular rash or crops of erosions, the clinical presentation of genital HSV infection in HIV is varied and can assume vegetative, hypertrophic, condyloma-like, nodular, ulcerative and tumour-like nodules or plaques. These unusual presentations often lead to a delayed diagnosis. We describe five immunocompromised HIV-positive patients with CD4 counts ranging from 114 to 326 cells/μL with unusual presentations of anogenital herpes.

Introduction: We present the case of a male adnexal tumor of probable Wolffian origin occurred to the right seminal vesicle of a 47-year-old man., Materials and Methods: The patient presented with a 2-month history of hematospermia. The diagnosis was achieved by transrectal ultrasound, CT of the abdomen and pelvis, and biopsy of both prostate and seminal vesicle. The patient was counseled for laparoscopic excision of the right seminal vesicle., Results: The right seminal vesicle, along with the tumor and the right vas deferens, were excised and clear margins were ensured by frozen section. Total operative time was 180 with 200 mL blood loss. The patient's recovery was uncomplicated and he was discharged on the fourth post-operative day. The histologic examination demonstrated a male adnexal tumor of probable Wolffian origin, which is a rare low-grade malignant neoplasm that has been previously described in the broad ligament, ovaries and retroperitoneum of females. The patient is free of relapse at a 20-month follow-up., Conclusions: This is the second report of this entity in a male. The laparoscopic approach for the excision of seminal vesicle neoplasms is a good treatment for its obvious benefits of minimal blood loss, short hospital stay and quick return to normal activity. The magnifications of the anatomical details of the pelvic floor help the surgeon in the dissection of the seminal vesicle from the other structures.

Background: The association of lichen sclerosus (LS) with genital squamous cell carcinoma is well recognized. However, the relationship between LS and verrucous carcinoma remains unclear., Objective: To evaluate the associations of genital and perianal verrucous carcinomas with LS., Methods: We conducted a retrospective study on patients with a genital or perianal verrucous carcinoma and reviewed their histopathology specimens and clinical notes. We also conducted a literature review., Results: We identified a total of 13 patients (including 6 women and 7 men) with a genital or perianal verrucous carcinoma. All 5 women with vulval verrucous carcinoma had coexisting LS (5/5), and 1 man with penile verrucous carcinoma had coexisting LS (1/3). In contrast, no coexisting LS was found in all 5 cases of perianal verrucous carcinoma (0/5). Half of the cases of verrucous carcinoma with coexisting LS had recurrences (3/6), while no recurrences were found in those without coexisting LS (0/7)., Conclusions: Our study and review of the literature demonstrate that vulval verrucous carcinoma is strongly associated with LS. In contrast, perianal verrucous carcinoma is not associated with LS. When genital verrucous carcinoma is diagnosed, it is important to consider LS as a potential concomitant diagnosis and offer appropriate treatments and close follow-up to detect recurrence of verrucous carcinoma.

Spermatic cord sarcomas (SCS) are very infrequent and sometimes misdiagnosed malignancies. Moreover, their optimal management remains undefined with ongoing controversy about the indications for adjuvant therapy. Histologically, liposarcomas are the most common type. Osteosarcoma is rarely observed in this location and combined tumours with this component have not been described. We present a case of SCS with mixed differentiation with both liposarcoma and osteosarcoma elements.

Perineal lipoma is a rare condition which is commonly associated with scrotal anomalies and may be diagnosed as ambiguous genitalia. We report on a baby with penoscrotal transposition (PST) consisting of bifid scrotum and hypospadias with chordee associated with perineal lipoma. The affected baby was one twin of an IVF pregnancy referred to our center for ambiguous genitalia by fetal ultrasound. Examination of the uterus revealed a dichorionic, diamniotic twin pregnancy. Fetal ultrasound and MRI in our center revealed an exophytic perineal mass, which likely represented a lipoma, separate from the abnormally appearing phallus and scrotum (hypospadias with chordee and a bifid scrotum). This likely fell into the PST spectrum. There were no additional abnormalities in the other structures and no structural abnormality of co-twin was detected. Fetal growth of both twins was appropriate for gestational age. Babies were born at term and the findings of the affected twin correlated with the fetal diagnoses. While some reports show PSTs are associated with multiple anomalies, in this case no additional anomalies were identified. Perineal lipomas are commonly associated with scrotal abnormalities and anorectal malformations. It is hypothesized that these anomalies develop because of the perineal lipoma. MRI combined with ultrasound clearly defined the anomaly prenatally and allowed for accurate prenatal counseling and coordination of postnatal care., (Copyright 2010 S. Karger AG, Basel.)

A case of a giant spermatic cord lipoma, discovered incidentally at the time of surgical exploration of the scrotum, is discussed.

We report here a case of cystic lymphangioma of scrotum presenting as acute scrotum due to haemorrhage. The diagnosis was confirmed on ultrasonography and magnetic resonance imaging and managed successfully by surgical excision. There was past history of bilateral congenital cataract for which the patient had undergone surgery with complete visual recovery. Scrotal cystic lymphangioma complicated by haemorrhage is rare; hence, the case is being reported with a review of literature.

Inflammatory myofibroblastic tumor (IMT) is an uncommon condition and only a few cases of IMT in the spermatic cord have been reported, with none associated with an undescended testis. We present the case of a man with an undescended left testis who had an IMT involving the spermatic cord. He was treated with surgery and no adjuvant therapy afterward. He was disease free at 2.5 years of follow-up. A brief discussion of the pathologic features and management of the condition is also provided.

We report an 8-month-old boy with stage 1 neuroblastoma, whose "testicular tumor" was removed during a "radical orchiectomy" by a pediatric surgeon who encountered a scrotal mass during a hernia repair. Pathologic examination of the specimen suggested seminoma and the surgeon sent the patient for cisplatin-based chemotherapy. However, follow-up examination showed a normal testis. Reexamination of the specimen in other laboratories proved neuroblastoma. The patient is tumor free after 36 months of follow-up. This case shows that in presence of hernia, distorted anatomy, and inguinal testis, paratesticular tumors can be misdiagnosed for the testis and cause great diagnostic and therapeutic difficulty.

Objective: To determine whether seminal vesicle amyloidosis (SVA, an unusual finding in prostatectomy specimens, with deposits usually localized and asymptomatic) affects the extension of prostate cancer into the SVs., Patients and Methods: We identified 73 cases of localized SVA from 6575 prostatectomy specimens, that were removed because of clinically localized prostate cancer. All cases were confirmed by Congo red staining and polarization microscopy. The mean thickness of the amyloid band was measured in each case and correlated with clinicopathological characteristics. The frequency of SV involvement by prostate cancer in the presence of amyloid was compared with the percentage of pT3b classifications in the absence of amyloid., Results: The mean (range) age of the patients with localized SVAs was 64.4 (52-73) years. The mean thickness of the amyloid band did not correlate with patient age, preoperative prostate-specific antigen levels, the weight of the prostates, or the Gleason score and T category of the prostate cancers. In the SVA group, seven cancers invaded the SVs (9.6%), which was not significantly different from the percentage of SV involvement by cancer in total sample (9.2%, P = 0.932)., Conclusions: The pathogenesis of localized SVA remains poorly understood, but SVA does not seem to provide an absolute or relative protection from SV involvement by prostate cancer.

Cutaneous metastasis of prostatic adenocarcinoma is a rare phenomenon. We present a 56-year-old African American man with metastatic disease in the skin and subcutis of the suprapubic and scrotal area 2 years after his initial diagnosis presenting as scrotal and penile edema and plaque like scrotal rash. We also review the literature on this subject.

This review focuses on the recent therapeutic advances that may affect the management of neoplastic anogenital human papillomavirus (HPV)-related lesions in human immunodeficiency virus patients: highly active antiretroviral therapy (HAART) and HPV vaccines. HAART shows limited benefit on the incidence of high grade intraepithelial lesions and cancer in cervix, vulva and anus. On the other hand, it seems to raise discretely the spontaneous regression rates of cervical low grade lesions -cervical intraepithelial neoplasia (CIN) grade I- and condylomas, as well as the regression after treatment of CIN II-III. The benefit of HAART in squamous intraepithelial lesion seems to be modest, mostly due to the improvement of the immune status. The usefulness of DNA-HPV in HIV is not well established. HPV vaccines represent a mid-term new possibility of prevention for these lesions according to the high effectiveness shown in clinical trials, although the lack of data about effectiveness and security in HIV patients restrict its application. Second generation vaccines, still to be developed, might better adapt the specific needs of these patients.

Introduction: Though theoretically in the paratesticular region one can develop any type of benign tumour of soft tissues, they are the lipomas, leiomyomas and adenomatoid tumours the most usual whereas the hemangiomas are less common. We contribute a new case of epididymis intrascrotal hemangioma (HI), valuing the bibliography that allows us to know the incidence and clinic-pathologic characteristics of these tumours., Material and Method: A 74-year-old patient includes for study with right scrotal tumour, who is practised orchiectomy. Hystopathologic study is realized. Of equal form there is realized a bibliographical examination of this type of tumours across Medline and of not index-linked search with conceptual review and of the literature., Results: The injury corresponds with a HI cavernous trombosed of epididymis with testicular parenchyma respected. Your hystopathologic diagnosis does not present problems, whereas the clinical one and ultrasonographic study, reaches the whole spectrum of tumours, benign and malignant of soft tissues. The number of intrascrotal hemangiomas of epididymis described in the literature is very limited., Conclusions: The scrotal tumours are necessary a preoperatory clinical and sonographic study completely, in spite of the fact that they are diagnosed the majority after your surgical removal. The complex system of the tissues on the zone paratesticular implies that the differential enclosed diagnosis does not allow to differentiate, malignant tumours of benign. The low incident of many of these masses has determined the mistake of standardized protocols for your diagnosis but also for their unified treatment.
