Simultaneous Sertoli Cell-Only Syndrome and Leydig Cell Tumor in a Patient with Azoospermia: A Rare Case Report

Abstract

Testicular cancers comprise 1–1.5% of entire cancers in men, and sex cord-stromal tumors include 5% of testicular cancers. This study aims to report a simultaneous Sertoli cell-only syndrome and Leydig cell tumor in the same patient. A 32-year-old man presented with a history of primary infertility for 3 years. Physical examination revealed normal secondary sexual characteristics. Two successive seminal fluid analyses revealed azoospermia. A scrotal ultrasound scan showed a 28 × 27 mm hypoechoic and hypervascular right testicular mass. Right radical orchiectomy and simultaneous left testicular biopsy were conducted. The histopathological examination revealed Sertoli cell-only syndrome and Leydig cell tumor with focal Leydig cell hyperplasia. Reversing fertility following the management of Leydig cell tumor is rarely mentioned in the literature. A study revealed that fertility recovered following 4 months of management in a primary infertile male. However, infertile men with nonobstructive azoospermia due to SCOS can only have a child by testicular sperm extraction technique. Despite the rare occurrence of Leydig cell tumor, it could be seen in association with Sertoli cell-only syndrome in infertile men with azoospermia. Clinical examination and imaging studies are important in these patients as the possibility of having a testicular mass is high among them.
