Abstract

Testicle tumors are a rare entity among men population, accounting for only 1-1.5% of all cancers among men. The stromal tumors of the sexual cord correspond just 4% of all testicular cancers.

We report the caso of a 91-year-old man with malignant Leydig cell tumor, presenting increase of the volume of scrotum, local pain and hyperemia. The are few cases in the literature, only 1 with pacient above 85 years old.

Bilateral congenital cryptorchidism and unilateral Leydig cell tumor in an adult presenting with gynecomastia and primary infertility: A case report

“…Neoplasms of the testis account for approximately 1–1.5% of all cancers among men. Furthermore, the rarest subset of these rare neoplasms belongs to the stromal tumors of the sex cord, which correspond to just 4% of all testicular cancers [1] . Among the testicular stromal tumors, Leydig cell tumors (LCTs) are the most common form, accounting for approximately 75% to 80% [2] , and overall they account for 1–3% among all testicular tumors in adults.…”
