Unusual cutaneous manifestations of miliary tuberculosis.

Cutaneous manifestations of miliary tuberculosis are extremely rare. We describe a 62-year-old woman with leukopenia who developed infiltrated dermal-hypodermal and ulcerative cutaneous lesions during the course of miliary tuberculosis. Miliary tuberculosis was diagnosed when Mycobacterium tuberculosis bacilli were isolated by cultures of the bronchoalveolar lavage fluid and blood and when acid-fast bacilli were detected on histopathologic examination of hepatic, pulmonary, and cutaneous biopsy specimens. With the increasing incidence of immunocompromised patients, unusual presentations of tuberculosis may be observed more often. Acute miliary tuberculosis of the skin is an exceptional manifestation that is due to acute hematogenous dissemination of M. tuberculosis to the skin. We describe a patient who had unusual cutaneous manifestations of miliary tuberculosis.
