"Were-wolf" cutaneous tuberculosis.

Lupus vulgaris is a variant of cutaneous tuberculosis. Its more destructive and mutilating clinical forms have become rarer in consonance of a general decline of cutaneous tuberculosis. It is rarely seen now in developed countries due to stringent control measures, improved quality of living and effective therapeutic regimens. Misdiagnosis, neglect, or late diagnosis may result in severe, ulcerative and mutilating "wolf eaten" skin lesions. This paper describes four such cases of "were-wolf" cutaneous tuberculosis. Early diagnosis and treatment is important to prevent much of the disfigurement.
