Bilateral testicular Leydig cell hyperplasia presented incidentally: A case report.

ABSTRACT

INTRODUCTION: Leydig cell hyperplasia or tumor represents less than 3% of all testicular tumors. It can be defined as an increase in the size and number of Leydig cell within the testicles. These cells are responsible for the production of testosterone in human males. CASE PRESENTATION Our patient is a forty-eight-year-old male presented with erectile dysfunction and decreased libido for the past six months. Ultrasound of the scrotum show bilateral hypoechoic testicular masses larger on the left size thus left orchidectomy was performed. Histopathology confirmed our diagnosis. DISCUSSION: Leydig cell hyperplasia (LCH) is a rare and mostly benign entity that affects both children and adults. In adults, it might be associated with variety of condition including Klinefelter's syndrome, exogenous human chorionic gonadotropin (hCG) therapy, and many others but it mostly occurs idiopathically. Scrotal ultrasound and tumor markers can be used to diagnose most of the patients with LCH. CONCLUSION: LCH should be differentiated from Leydig cell tumor to avoid unnecessary and sometimes harmful intervention in the future.
