ABSTRACT

Background: Erythrasma is a superficial pseudomycosis caused by Corynebacterium minutissimum, affecting folds and feet interdigital regions, and characterized by erythematous, brown, scaly patches, exhibiting red fluorescense under Wood’s light.
Objective: To determine the prevalence of erythrasma in patients with HIV infection and its relation with their immunosupression state.
Material and method: An open, prospective, longitudinal and observational study was performed in a General Hospital in Cancun, Quintana Roo, Mexico, from October 2013 to February 2014. All patients with interdigital lesions were examined with a Wood’s lamp and direct examination was performed with clorazole black. General characteristics and concomitant diseases were recorded.
Results: We examined 101 patients, of whom 31 (30.69%) were diagnosed with erythrasma based on red fluorescense under Wood’s light and the identification of corynebacteria by Gram staining. The main clinical findings were scaling, erythema and pruritus. The mean age of the patients was 36.8 ± 7 years. We also found dermatophytes hyphae in 4 cases. Incidence of erythrasma was independent of CD4 counts.
Conclusions: Interdigital erythrasma is a common condition; in our sample of 101 patients with HIV infection, 30% had erythrasma that can be easily confused with interdigital tinea. It was not found a statistically significant relationship between the cell count CD4 and the interdigital erythrasma.
