Wilms' tumor (WT) is the most common primary renal tumor in children. Common sites of metastases are lungs, liver and regional lymph nodes. Testicular and paratesticular metastasis due to WT have been reported but it is extremely rare. We report a 33-month -old male with bilateral WT and metastasis to right spermatic cord.

Paratesticular liposarcomas are rare tumors and are often reported as isolated cases. Patients usually present with a painless scrotal or inguinal mass, mimicking inguinal hernia. They refer to liposarcomas arising from the spermatic cord, testicular tunics, and epididymis. We report a case of bilateral scrotal swelling which was misdiagnosed as inguinal hernia. Intraoperative diagnosis of test...

We describe a case of simultaneous bilateral paratesticular neuroblastoma presenting as spermatic cord tumors in a 6-month-old boy. He was diagnosed as having stage IV neuroblastoma originated from right adrenal gland with metastases to the paratesticular region, right femur, and right maxilla. The tumor showed favorable biological features according to Shimada’s classification and had no N-myc...

The versatile histopathology, clinical presentation, and biologic behavior of testicular neoplasms reflect the complex composition of the male gonad. Each component can develop different tumor types; thus, there are testicular germ cell tumor (TGT), sex cord/stromal tumor, miscellaneous tumors arising from rete testis or paratesticular structures, and tumors not specific to testicular parenchym...

Spindle cell rhabdomyosarcoma is a rare variant of embryonal rhabdomyosarcoma that affects young males and most commonly involves the paratesticular region. We report a case of paratesticular spindle cell rhabdomyosarcoma in a 14-year-old boy, who presented with a painless scrotal mass. Left inguinal orchidectomy was performed. Histopathological and immunohistochemical examination of the mass r...

An 81-year-old man had a papillary adenocarcinoma infiltrating the rete testis with involvement of the epididymis and paratesticular soft tissue. The tumor was composed of papillary structures to focally solid areas with cells having abundant eosinophilic to clear cytoplasm, markedly atypical nuclei, and brisk mitotic activity. Invasive growth and extensive necrosis were present. Morphology, im...

Rhabdomyosarcoma (RMS) is a malignant tumor of mesenchymal origin typically affects children and adolescents, with an annual incidence of 4.3 cases per 1 million population aged <20 years. Para testicular RMS is rare, constituting 4-7% of all RMS in children and young adults. Here we report a case of 16-year old boy with right paratesticular solid mass. Ultrasound revealed vascular paratesticul...
