Tuberculosis verrucosa cutis of the scrotum

A 13-year-old boy had asymptomatic slowly progressive warty growth on the scrotum for 4 years. Examination revealed a 4 cm x 2 cm keratotic, nontender, indurated plaque on the right side of the scrotum. Histopathological examination of the lesion showed epithelioid cell granuloma with giant cells and lymphocytes in the dermis. Mantoux test was 15 mm x 20 mm. A diagnosis of tuberculosis verrucosa cutis of the scrotum was made. Six months of therapy with INH 150 mg and rifampicin 300 mg daily resulted in complete clearance of the lesion.
