Paratesticular mesothelioma is a rare differential diagnosis in the presence of scrotal hydrocele. A 17-year-old boy presented with a 3-year history of progressive hydrocele. Sonography revealed a large left paratesticular mass within the hydrocele. Serum tumor markers were negative. Left hydrocelectomy was performed and pathological analysis of the epididymal mass revealed a well-differentiated papillary mesothelioma. We discuss the sonographic and pathological findings of this rare neoplasm.

Coexistence of bilateral seminomas and adenomatoid tumor is rare. We encountered an interesting case of bilateral testicular seminomas along with a paratesticular nodule which was diagnosed as an adenomatoid tumor on histology. Although seminomas and adenomatoid tumor are frequent neoplasms, bilaterality and their coexistence have been rarely described and can pose diagnostic difficulties. Herein, we describe a case of a 53-year-old man who presented with bilateral testicular swellings which were diagnosed as bilateral seminomas with an adenomatoid tumor in the left paratesticular region on histopathology...

BACKGROUND: To evaluate the effect of insulin treatment on the incidence and/or severity of hepatocellular carcinoma (HCC) in a mouse model of HCC based on diabetes. METHODS: We recently reported that neonatal streptozotocin (STZ) treatment causes type 1 diabetes and subsequent HCC in ddY, Institute for Animal Reproduction (DIAR) mice. Newborn male DIAR mice were divided into three groups based on STZ and insulin (INS) treatment. STZ was subcutaneously injected (60 mg/g) into the STZ-treated group (DIAR-nSTZ mice, N = 13) and the STZ/insulin-treated group (DIAR-nSTZ/INS mice, N = 20)...

OBJETIVE: Primary undifferentiated pleomorphic sarcoma (UPS) of the testicular tunics is rare, and synchronism with other malignancies of the urinary tract is uncommon, and may complicate the staging and therapeutic approach. We report the case of a patient diagnosed with primary paratesticular UPS with synchronous Renal Carcinoma. METHODS: Patient presenting with intrascrotal tumor who underwent left radical orchiectomy. In staging work up studies a second urologic neoplasia was found in the kidney...

Paratesticular tumors are rare and often benign causes of scrotal masses. Intrascrotal angiolipomas are an uncommon paratesticular tumor that has seldom been reported in the literature. This report describes a 77 year old man who presented with a 15 cm extratesticular mass. The mass was removed due to increasing discomfort and specimen pathology confirmed it as an angiolipoma. This case highlights the feasibility of conservative management for slow growing masses, such as angiolipomas.

We report the dramatic case of a 18-year old patient with immediately metastatic round cells paratesticular liposarcoma. It is a rare tumor that develops in the fatty tissue surrounding the testicle and the spermatic cord. Clinical and radiological signs are nonspecific and diagnosis is usually based on surgical specimen examination. The treatment involves radical inguinal orchiectomy, sometimes extended to adjacent structures. Adjuvant radiation therapy could be used in the case of locally advanced mass or incomplete resection...

We report an extremely rare manifestation of immunoglobulin G4-related disease, presented with hydrocele testis. A planned hydrocelectomy was converted to a high orchiectomy because of bloody fluid, suggestive of paratesticular malignancy. The histopathology showed vaginalitis, which was finally diagnosed as immunoglobulin G4-related disease. To the best of our knowledge, this is the first report of immunoglobulin G4-related disease representing hydrocele testis.

Ovarian epithelial type tumour of testis are extremely rare tumours that resemble ovarian surface epithelial tumours. They usually present as testicular or paratesticular tumours and can be serous, mucinous, endometrioid or Brenner tumour. Serous and mucinous types account for the majority of tumours. The tumours are benign, borderline or malignant, commonly borderline. Here, we report a case of high grade serous cyst adenocarcinoma of testis which manifested as extensive metastasis in supraclavicular, mediastinal and abdominopelvic groups of lymph nodes, lung and adrenal gland without clinical evidence of an overt primary tumour...

Paratesticular aggressive angiomyxoma is a very rare tumour in males. Most of documented cases of aggressive angiomyxomas have been seen in genital, perineal and pelvic regions in women of child bearing age. We report two cases of aggressive angiomyxomas in males who presented with inguinal swellings. A globular mass with greyish white, glistening cut surface was received after excision of the mass. Microscopic examination revealed a paucicellular tumour comprising of spindle shaped cells along with vessels of varying calibre...

Cryptorchidism is a very common anomaly, affecting 2-4% of male infants and is more common in premature infants. The long-term outcome despite orchidopexy still remains problematic and controversial with a risk of developing cancer 5-10 times greater than normal. Paratesticular tumors are mostly benign and very rare in children however malignant paratesticular tumors do arise, the most common being rhabdomyosarcoma. Primary paratesticular seminoma is extremely rare by itself and in most cases is associated with foci of seminoma within the testis...

OBJECTIVES: Aggressive angiomyxoma is known as a mesenchymal tumor of premenopausal women and it is extremely rare in men. METHODS: Herein, we report a 66-year-old male with a firm scrotal mass that had gradually enlarged over 20 years. RESULTS: Radiological studies revealed 10 x 15 cm mass lesion confined to right scrotum with neither local invasion nor distant metastasis. Inguinal orchiectomy was performed and histopathology showed characteristic features of an aggressive angiomyxoma occupying paratesticular region, which was a challenging diagnosis due to its unexpected occurrence in the male gender...

Ovarian-type epithelial lesions of the testicle and paratesticular tissue are uncommon, especially invasive serous adenocarcinoma with just 18 cases reported in the literature. While the majority of these tumors occur in adults with an age range from 16 to 87 years, just one patient was less than 10 years old. Herein, we report only the second case of invasive serous adenocarcinoma occurring in first decade of life, that of a 7 year-old boy. Additionally, clinical presentation, imaging, histopathology, immunohistochemistry, and clinical follow-up of invasive serous adenocarcinoma of the testicle are discussed along with review of the literature...

Paratesticular region is an obscure anatomical region that includes spermatic cord and its contents, tunica of the testes, epididymis and appendices of epididymis and testis. Paratesticular tumours may closely resemble and be clinically indistinguishable from testicular tumours, resulting in a diagnostic dilemma. Preoperative distinction between the benign and malignant paratesticular tumour is extremely difficult, resulting in difficulty in diagnosis and management. We hereby present a case of a 56-year-old male who reported with a painless bilateral scrotal mass and underwent surgical excision of the same...

Testicular and paratesticular cystadenomas arise from an oviduct-like structure, which, morphologically, is almost identical with the ovarian surface epithelium. These are very rare benign tumours of adults. They present as asymptomatic cystic lesions. Bilateral paratesticular cystadenomas are associated with the Von-Hippel-Lindau syndrome and may be associated with infertility. 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 Müllerian-type epithelial tumour with a low malignant potential...

Desmoplastic small round cell tumor (DSCRT) is a rare malignancy most often seen in the abdomen or pelvis of young men. Unfortunately, this disease is usually metastatic at diagnosis and has dismal outcomes. We describe a case of isolated paratesticular DSCRT in a 14-year-old male successfully treated with surgical resection, chemotherapy, and adjuvant radiation, and we present a review of the relevant literature. It appears that isolated, paratesticular DSCRTs have a markedly better outcome than the classic abdominal or pelvic location...

Aggressive angiomyxoma (AAM) particularly testicular origin is a rare benign mesenchymal myxoid tumor which is locally aggressive, blatant for local recurrence, and may metastasize. It occurs mostly in females of childbearing age and extremely rare in males. AMM particular testicular origin is not reported in literature yet. This is a 65-year-old man who had a right scrotal swelling. Ultrasound scrotum showed a soft tissue tumor of the right testis. The patient underwent radical right orchidectomy of which histopathologically confirmed to be a paratesticular AAM with clear resection margins...
