We present the case of a rnale, 28 year old who consulted for fever, loss of weight and axillary ulcer. Clinically had two ski n lesions where cutaneous tuberculosis was proven (lupus vulgaris-scrofuloderma). The ski n lesions led to the diagnosis of lung tuberculosis and tuberculous adenitis. In this case all the diagnostic criteria for cutaneous tuberculosis were completed: presence of active tuberculosis in another place, presence of acid alcohol resistant bacilluses in the lesion, positive reaction to tuberculin test, physical signs and appropiate answer to the treatment.
