RESUMO
Cutaneous tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. It is uncommon (1% of all cases of tuberculosis), but has increased due to the human immunodeficiency virus epidemic and to pharmacologic immunosuppression. It presents a wide variety of clinical forms depending on how bacteria reach the skin and on the immune status of the patient. We present two cases of cutaneous tuberculosis diagnosed in the Hospital Clínico de la Pontificia Universidad Católica de Chile. We emphasize the difficulty in diagnosis and classification of this disease and briefly discuss on the different diagnostic and therapeutic approaches.

La tuberculosis (TBC) cutánea es una enfermedad infecciosa crónica causada por Mycobacterium tubercu losis. Es una patología poco frecuente (1 por ciento de todos los casos de TBC); no obstante, ha aumentado debido a la epidemia del virus de la inmunodeficiencia humana y la presencia creciente de la inmunosupresión farmacológica. Presenta una gran variedad de formas clínicas que dependen de cómo llega el bacilo a la piel y del estado inmunológico del individuo. A continuación, presentamos dos casos clínicos de TBC cutánea vistos en el Hospital Clínico de la Pontificia Universidad Católica de Chile y una revisión del tema.
