title: Verrucous plaque on the back of a hand.
abstract: We report the case of a 44-year-old slaughter-house operator with a skin lesion that had been present for two years on the back of his left hand. The lesion had increased progressively in size despite numerous topical treatments. Physical examination revealed an infiltrated erythematous-violet plaque with a verrucous surface featuring numerous orifices draining purulent material. Histologic study of the lesion disclosed tuberculoid granulomatous infiltrates at the dermoepidermal limit. Presence of Mycobacterium tuberculosis, together with other epidemiologic, clinical, histologic, and immunologic data, permitted a diagnosis of tuberculosis verrucosa cutis to be made. The excellent response of the patient to treatment confirmed this hypothesis. However, polychemotherapy withdrawal was temporarily needed due to analytical abnormalities.
