Bacillary angiomatosis on a region of burned skin in a immunocompetent patient.

Bacillary angiomatosis usually develops in immunodeficient patients with a history of contact with cats. We report a 21-year-old immunocompetent woman with facial angiomatous lesions following a second-degree burn and without a history of direct contact with cats. The diagnosis of bacillary angiomatosis was based on the demonstration of bacilli in histological sections stained by the Warthin-Starry method. The lesions resolved 2 months after treatment with oral erythromycin for 8 weeks. This case emphasizes that bacillary angiomatosis may be seen in immunocompetent individuals and may be transmitted in other ways than cat scratches, e.g. by arthropods.
