Bacillary angiomatosis in an HIV-1 infected adult at early stage of immunosuppression, Abidjan, Côte d'Ivoire

Human immunodeficiency virus (HIV)-associated bacillary angiomatosis has rarely been described in Africa. We report here the first case in Côte d'Ivoire. Although in industrialised countries bacillary angiomatosis has been described in patients with low CD4 count, this episode occurred in the first year following HIV-seroconversion in an adult patient with more than 500 CD4 cells per cubic millimetre. Symptoms rapidly and totally disappeared under erythromycin treatment, although with a relapse two years after the end of the first episode. In Africa where people living with HIV often present chronic cutaneous lesions, bacillary angiomatosis may be under-diagnosed. Bacillary angiomatosis must be systematically considered in face of lesions similar to Kaposi's sarcoma. Improving knowledge on symptoms of bacillary angiomatosis in Africa should lead to better treatment and a better estimation of its true frequency which may be underestimated.
