Background: Previous studies in Africa have shown severity of toxidermia with a risk of mortality and mucosal synechia. Our objective was to study the epidemiological, clinical, etiological and evolutionary aspects of toxidermia in Dakar. Methods: A cross-sectional retrospective study was conducted at the Department of Dermatology of the Hospital Le Dantec from January 2001 to December 2015. She identified all of the toxidermia cases of hospitalization in this department. The diagnosis was based on the French criteria for drug accountability. Results: Two hundred cases of toxidermia were recorded. The hospital frequency was 9.2%. The sex ratio was 0.61. The average age was 33 years. Clinical forms of bullous toxidermia were Stevens Johnson/Lyell in 54% (n = 108), erythema multiforme in 3% (n = 6), and fixed pigmented erythema in 2% (n = 4). Mucosal involvement was noted in 56.5% (n = 113). Visceral involvement was noted in 15% (n = 30) with respiratory involvement in 24 cases of SSJ/NET and 6 cases of DRESS. The drugs identified were antibiotics in 38,7% (n = 53), analgesics in 15,3% (n = 21), anti-comitials in 13,1% (n = 18), antiretrovirals in 11,7% (n= 16), antituberculosis drugs in 9,5%% (n = 13) and medicinal plants in 11,7% (n = 16). The outcome was favorable in 62.5% (n = 125). Death was noted in 12%. Conclusion: Toxidemia in Dakar are characterized by predominance in severe clinical forms in young adults and mortality was related to infectious and hydro electrolyte complications.
