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 angiomat osis was based on the demonstration of bacilli in histological sections sta ined by the Warthin-Starry method. The lesions resolved 2 months after trea tment with oral erythromycin for 8 weeks. This case emphasizes that bacilla ry angiomatosis may be seen in immunocompetent individuals and may be trans mitted in other ways than cat scratches, e.g. by arthropods.
