Malignant sertoli cell tumor of the testis with a large retroperitoneal mass in an elderly man.

CASE REPORT A 78-year-old man presented with a new growth in his right testis which was uncomfortable, but not painful. He reported a progression in growth over the past few months, and stated that it was doubled in size in the previous month. His past medical history included mumps as a child, hypertension, and recurrent urolithiasis with reported spontaneous passage of calcium oxalate calculi several months prior to this presentation. Physical exam revealed a moderately enlarged right hydrocele and a firm right testicular mass as well as right inguinal adenopathy consisting of non-tender, small nodes. There was no evidence of gynecomastia.
