Generalized anetoderma in a patient with HIV and dual mycobacterial infection.

A middle-aged HIV infected man receiving treatment for pulmonary tuberculosis, presented with a febrile illness along with evanescent, erythematous nodular lesions all over the body. On examination, he had features suggestive of lepromatous leprosy with lesions of erythema nodosum leprosum. In addition, there were multiple small, circumscribed areas of slack skin, clinically and histopathologically suggestive of anetoderma. Both leprosy and HIV infection are known to give rise to lesions of anetoderma. Pathogenesis of anetoderma in these infectious conditions is discussed.
