Exfoliative erythroderma and palmoplantar hyperkeratosis associated with Majocchi's granuloma by Trichophyton tonsurans in a patient with AIDS.

Background: Dermatophytoses are skin superficial mycoses in which clinical manifestations are directly related to the virulence of the infecting microorganism or the host immunity.

Case Report: We describe a severe case of dermatophytosis associated with exfoliative erythroderma, substantial palmoplantar keratoderma, onychodystrophy affecting all nails, diffuse non-scarring alopecia and tissue fungal invasion by Trichophyton tonsurans, which led us to the diagnosis of AIDS. Direct examination and culture for fungi from skin scraping from two different sites were performed.
