| Summary: | 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.
