Abstract:
Leydig cell tumors (LCTs) are uncommon testicular neoplasms, accounting for 1-3 % of cases. While most are benign, a small subset demonstrates malignant potential, making accurate diagnosis and tailored management essential. We report the case of a 52-year-old man with a history of cryptorchidism and prior orchiectomy who presented with inguinal pain and infertility. Imaging revealed a solitary testis with a small intratesticular lesion. Intraoperative frozen section suggested a Leydig cell tumor, and partial orchiectomy was performed. Final pathology confirmed a benign LCT. The patient remains recurrence-free at follow-up, highlighting the role of testis-sparing surgery in selected cases.
