title: [An uncommon cause of gynecomastia: testicular Leydig cell tumor. Hormonal profile before and after orchiectomy].
abstract: Leydig cell tumors (LTC) are uncommon neoplasms arising from gonadal stroma that account for 1-3% of all testicular tumors. We report a case of LCT in a 36 years old man who had been suffering from painful bilateral gynecomastia for one year. Endocrine function tests showed decreased gonadotropin concentrations, and reduction of testosterone/estradiol ratio. Ultrasonography revealed a 10-12 mm hypoechoic area in the right testis, not evident on physical examination. Right orchiectomy was performed and histological examination confirmed the supposed existence of a LCT. After surgery, the gynecomastia has completely disappeared and hormonal alterations returned to normal.
