PURPOSE: To report the results from International Society of Pediatric Oncology (SIOP) Malignant Mesenchymal Tumors studies (MMT 89 and 95) of males with nonmetastatic paratesticular rhabdomyosarcoma. METHODS: From 1989 to 2003, 159 patients were included. Radical inguinal orchidectomy was recommended, but retroperitoneal lymph node (LN) assessment was based on imaging alone. The treatment was stratified by stage (SIOP tumor-node-metastasis staging system) and histology...

The cystadenoma of the testis and paratestis arising from an unequivocal oviduct-like structure, which is morphologically almost identical with those of the ovarian surface epithelium. These are very rare benign tumors of young adults. They present as asymptomatic cystic lesions. Bilateral paratesticular cystadenomas are strongly associated with von Hippel-Lindau syndrome and correlate with infertility. It is a neoplasm with low malignant potential. Most cystadenomas are benign but a few cases of malignant transformation of embryonic remnants have been reported in the appendix testis, including cases of adenocarcinoma, cystadenocarcinoma, and a low malignant müllerian-type epithelial tumor...

In daily clinical practice, intrascrotal lesion are commonly detected, both by clinical examination either by ultrasound scan. While 95% of testicular lesions are malignant, most paratesticular lesions are benign. Among these, intrascrotal lipomas must be take into account in differential diagnosis. When they originate from scrotal wall, they named "primary scrotal lipoma". We describe a case of a primary intrascrotal lipoma diagnosed after surgical excision in a young man presented at our Urological Department complaining a painful left scrotal mass...

OBJECTIVES: Testicular (TT) and paratesticular (PT) tumors account for 1-2%of all infant solid tumors. Due to the increased frequency of benign tumors, conservative management is recommended. Our experience and the therapeutic approach adopted considering testis-sparing surgery, was reviewed. METHODS: A retrospective observational study concerning testicular and paratesticular tumors in our hospital between 1998 and 2016, was performed. Age, side, symptoms, imaging, treatment methods, histological findings and evolution were reviewed...

Adenomatoid tumor is an uncommon benign mesothelial neoplasm, usually localized in the epididymis. It is the most common paratesticular tumor of middle-aged patients (average age of clinical presentation: 36 years). However, these tumors in pediatric and pubertal patients are extremely rare. Due to their rarity, we present a case of adenomatoid tumor of the tail of the epididymis in a 16-year-old patient. After systematic research of the current literature, we did not find another case report of epididymal adenomatoid tumor in a male patient aged 16 years old or less...

Malignant mesothelioma is an uncommon neoplasm that develops from serous surfaces, and rarely from the tunica vaginalis. Although atypical in any location, paratesticular presentation is exceedingly infrequent as only 0.3% to 1.4% of mesothelioma cases arise from the tunica vaginalis. Fewer than 300 cases have been reported with very few descriptions of long term follow up and multimodal therapy. Here we describe a patient with 2 years of follow up for metastatic mesothelioma treated with orchiectomy, chemotherapy and robot-assisted laparoscopic retroperitoneal lymph node dissection...

Paratesticular sarcomas are a rare entity and provide a unique clinical challenge due to their slow growing, often painless natural course. Adding to this challenge is the complex anatomy of the scrotum that allows these masses to mimic other conditions, including inguinal hernia, cysts, or fluid collections. We report such a case and our approach to an 83-year-old male with dedifferentiated liposarcoma of the spermatic cord with a history of inguinal hernia. In doing so, we highlight the need for thorough evaluation of scrotal masses and the management of these rare, though well-described, tumors...

PURPOSE: To evaluate factors associated with progression-free and disease-specific survival in patients with paratesticular rhabdomyosarcoma, we performed a cohort study. Also, since many patients present to our institution after initial therapy, we analyzed the effects of salvage therapy for scrotal violation. PATIENTS AND METHODS: We retrospectively reviewed the records of all consecutive patients with histologically confirmed paratesticular rhabdomyosarcoma treated at our institution between 1978 and 2015...

PURPOSE: Exposure to asbestos is thought to cause the large majority of pleural mesotheliomas in the USA. It is unknown whether asbestos exposure plays a role in the etiology of rarer forms of mesothelioma, e.g., those located in the pericardium or in the tunica vaginalis of the testis. In order to address this question, we sought to determine whether geographic patterns of incidence of these mesotheliomas have paralleled those of pleural mesotheliomas. METHODS: We used age-adjusted incidence data from the nine populations served by the National Cancer Institute's Surveillance, Epidemiology, and End Results program during 1973-2011...

Paratesticular malignant mesothelioma is an extremely rare type of mesothelioma with only a limited number of reported cases. Its clinical differentiation is challenging, and its diagnosis is almost exclusively accidental. The major risk factor is exposure to asbestos, typically with a long latency between exposure and diagnosis. The current study presents the clinical data of two patients diagnosed with paratesticular malignant mesothelioma. We evaluated a large spectrum of risk factors in the patients histories...

Physicians will be rarely confronted with epididymal tumours. These represent only 5% of intrascrotal tumours and are mostly (75%) benign. We report the case of a 50-year-old white male who was presented with a 5-year history of a slow-growing, left scrotal mass, noted through self-examination. Ultrasound study of the scrotum identified a well-circumscribed paratesticular mass. On inguinal surgical exploration, a solid, encapsulated, grey-white mass at the tail of the left epididymis was identified and excised, with intra-operative pathological consultation showing no signs of malignancy...

Primary paratesticular tumours are very rare and the spermatic cord (SCT) is the most frequent site of origin, with 20% of malignancy. Although liposarcoma is the most frequent histotype (46.6 %), less than 200 cases have been reported in the literature. We report the case of a 56-year-old man who presented a giant scrotal mass of 25 years of evolution and measuring 40 × 40 cm. It could be considered the greatest paratesticular liposarcoma described to date. Computed tomogaphy (CT) revealed mass features consistent with liposarcoma and the simultaneous presence of bilateral inguinal hernia with bladder involvement...

We report a 16-year-old male patient diagnosed with paratesticular rhabdomyosarcoma and mediastinal tuberculous lymphadenitis. The differential diagnosis between high or early stage of rhabdomyosarcoma and tuberculosis (TB) was critical in this patient without a history of TB. Unexpected lymphadenopathies detected during the staging of patients with malignancy should be carefully evaluated, and TB should be taken into consideration in the differential diagnosis especially in underdeveloped and developing countries...

A 20-day-old boy was presented with left scrotal swelling, clinically diagnosed as hydrocele. Ultrasonographic findings suggested hydrocele with paratesticular mass. Intraoperatively we found paratesticular mass, separate from left testis. Specimen revealed fibroconnective tissue with mucoid degeneration and focal areas of calcification suggesting meconium periorchitis. It is important to consider meconium periorchitis as one of the etiologies, thereby avoiding unnecessary orchidectomies.

BACKGROUND: Lymph node sampling is integral in the management of extremity and paratesticular rhabdomyosarcoma (RMS). The aim of this study was to determine overall surgical compliance with treatment protocols and impact of nodal sampling outcomes in these tumors. METHODS: A query of the surveillance, epidemiology, and end results program (SEER) database was performed from 2003 to 2008 for patients <19years of age with RMS. Data obtained included demographics, five-year survival and rate of nodal sampling...

OBJECTIVE: To describe the major imaging features, together with clinical data, of paratesticular sarcomas. METHODS: A retrospective analysis was performed of available imaging and clinical data of 77 consecutive cases of paratesticular sarcoma referred to the soft tissue sarcoma centre at **BLINDED**, between January 2006 and January 2015. RESULTS: Of the total cases, 87% had been referred post-operatively, 43% of which had been imaged pre-operatively and 24% of which required re-resection due to incomplete initial excision...
