Testicular non-metastatic paraganglioma: the first case report

Paragangliomas are tumors that develop from neural crest cells spread by the sympathoadrenergic neuroendocrine system. Our case is a testicular paraganglioma located exculisively in the testis and it is the first benign case in the English literature. A 60 years old male patient presented to our clinic with painless right scrotal mass. Preoperative scrotal ultrasound revealed a vascularized, mass lesion with two lobules completely filling the middle and lower right testis, measuring 40x24 mm in which anechoic cystic areas were observed. The patient then underwent right radical inguinal orchiectomy. Histopathologically and immunohistochemically, the diagnosis was testicular paraganglioma. Subsequent whole body-computerized tomography examinations revealed no suspicious lymph node or metastatic focus
