title: [Cutaneous tuberculosis: case report].
abstract: Cutaneous tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. It is not very frequent and particularly difficult to diagnose. It incidence ranges between 1.5 and 4% of all extrapulmonary tuberculosis, according to bibliography. The clinic presentations depend on the arrival via of the bacillus to the skin, the patient's immune state and the environment. We show a cutaneous tuberculosis on a child with chronic dermatologic lesions, with torpid evolution, without response to treatments; the skin biopsy showed caseous granulomas. The aim is to show a patient with an infrequent clinic presentation of this disease, to emphasize the importance of an early recognition and treatment, avoiding the appearance of complications and sequels.
