title: Extensive systemic sarcoidosis with testicular involvement mimicking metastatic testicular cancer.
abstract: Sarcoidosis is an idiopathic, multisystem disease that rarely involves the genitourinary tract. Here we present an unusual case of testicular sarcoidosis with extensive lymphadenopathy that mimicked a metastatic testicular tumor. A 27-year-old male presented with a palpable right testicular mass accompanied by multiple palpable inguinal lymph nodes. The scrotal ultrasound showed a hypoechoic lesion at the inferior portion of the right testis. Extensive enlarged lymph nodes were noted in multiple areas on the abdominal computed tomography. Preoperative testicular tumor markers were within the normal range. Exploration of the right testis with a frozen section analysis of the right testicular mass and of a palpable right inguinal lymph node showed granulomatous inflammation. The testis was salvaged and the final pathological diagnosis was sarcoidosis. Treatment with high-dose corticosteroids resulted in complete resolution of the intratesticular mass and a significant decrease in the extent of the lymphadenopathy.
