Testosterone secreting adrenal adenoma in an adult female patient.

Adrenal tumours that secrete testosterone are extremely rare and we describe such a case in a 35 years old female with virilization. She had steroid biochemical profile in normal limit, except increased serum testosterone level. She had left adrenal adenoma 7.5 X 6.4 cm in size, her ovaries were normal. After left adrenalectomy the serum testosterone level returns to normal and has remained in the normal range. Hirsutism decreasing gradually and menstruation restarts after 3 months. Histopathological examination confirmed the diagnosis of adrenal adenoma.
