VERRUCOUS PLAQUE ON THE BACK OF A HAND

We report the case of a 44-year-old slaughterhouse operator with a ski n lesion that had been present for two years on the back of his left h and. The lesion had increased progressively in size despite numerous t opical treatments. Physical examination revealed an infiltrated erythe matous-violet plaque with a verrucous surface featuring numerous orifi ces draining purulent material. Histologic study of the lesion disclos ed tuberculoid granulomatous infiltrates at the dermoepidermal limit. Presence of Mycobacterium tuberculosis, together with other epidemiolo gic, 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, polychem otherapy withdrawal was temporarily needed due to analytical abnormali ties.
