Leydig Tumor

Leydig tumor is a tumor of interstitial cells (Leydig cells) located in the testicles. These cells are responsible for the production of male sex hormones, in particular testosterone.

Leydig tumor often leads to increased secretion of testosterone, which causes premature puberty (virilization) in boys who have not reached puberty. Clinically, this is manifested by an enlarged penis, the appearance of hair in the groin area and on the face, acne, accelerated growth of bones and muscle mass.

Diagnosis of Leydig tumor is based on the detection of elevated levels of testosterone and its metabolites. An ultrasound examination can reveal a mass formation in the testicle. The final diagnosis is established based on histological examination of the tumor after its surgical removal.

Treatment for Leydig tumor consists of organ-conserving surgery or removal of the affected testicle. The prognosis is usually favorable. After successful treatment, the symptoms of virilization regress.
