The purpose of this study was to describe mucocutaneous manifestations observed in persons living with human immunodeficiency virus (PLHIV) in Cotonou, Benin. A transverse retrospective study was carried out on the records of PLHIV who underwent follow-up at the Military Teaching Hospital in Cotonou from February 2002 to September 2005. The files of all eligible adult patients examined by dermatologists prior to initiation of antiretroviral treatment were reviewed. Dermatologic manifestations were defined as any cutaneous or cicatricial lesion of the skin. Data was analyzed using the EPI INFO software package. (version 6.0). A total of 152 patient files were included. The sex ratio was 1.10 with a female predominance. Mean age was 37.8 years. HIV1 was predominant (98%). Two-thirds of patients were as stage 3 according to the WHO classification. A total of 276 dermatologic manifestations were identified. The most common manifestations were buccopharyngeal candidiasis (24.6%), prurigo (20.6%), shingles (11.6%), and dermatophytosis (10.5%). The mean CD4 lymphocyte level was 106 cells/mm3. The CD4 level was below 100 cells/mm3 in 52% of cases involving candidiasis and 60% of cases involving prurigo. Dermatologic findings in this study were identical to those described in most studies from Africa and Asia. However the low prevalence of Koposi's sarcoma and seborrheic dermitits was surprising given the advanced stage of immunodepression in our patients. The most frequent mucocutaneous manifestations of HIV infection in Benin are infectious disease and prurigo.
