title: Bacillary Angiomatosis in Immunocompetent Patient with Atypical Manifestations.
abstract: Bacillary angiomatosis is an infectious disease caused by two Gram-negative bacilli; this disease usually affects immunosuppressed hosts with a history of cat scratch. We report a rare case of bacillary angiomatosis in an immunocompetent 26-year-old woman with no history of exposure to cats, and with atypical clinical features (very pruritic vascular papules and nodules with ulceration and hemorrhage on the right arm and fingers). She was successfully treated with clarithromycin for 3 months. Bacillary angiomatosis must be kept in mind in the differential diagnosis of any papules and nodules in cases of unknown etiology and also in immunocompetent patients and HIV-negative individual.
