Abstract:
Leydig cell tumors (LCTs) are rare testicular tumors that may be a cause of precocious puberty in males. We present a 5-year-old boy with a five-month history of pubic hair appearance associated with an increase in penile length, scrotal hyperpigmentation, change in body odor, and bone age advanced by two years. His hormonal tests revealed the diagnosis of pseudo precocious puberty. Testicular ultrasound showed a unilateral right testicular enlargement. Surgery was performed to remove the mass. Histopathology confirmed the diagnosis of LCT. This case report highlights the importance of consideration of testicular tumors in boys with precocious puberty.
