[Problem of cutaneous tuberculosis].

Case histories of 97 patients were analysed to study the diagnosis, differential diagnosis and incidence of recurrences of tuberculosis of the skin. A combined examination revealed Basin erythema in 57.7% of the patients, lupus vulgaris in 29.9% and papulonecrotic tuberculosis of the skin in 12.4%. Recurrences were recorded in 15.4% of the cases. Our study gives evidence that tuberculosis of the skin is diagnosed from the combined examination of the patient in which histologic study of a skin biopsy specimen is most essential. The differential diagnosis of tuberculosis of the skin makes difficult the distinction between the disseminated forms and allergic vasculitis and sarcoidosis of the skin. The relapse depends on how adequate the major and antirecurrence courses of antibacterial therapy were.
