title: Diagnosis of HIV infection on the basis of histoplasmosis-related oral ulceration.
abstract: Histoplasmosis is an endemic systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum. In immunocompromised patients, histoplasmosis generally occurs as an opportunistic disease, with dissemination to various organs. Cutaneous involvement is observed in 38% to 85% of cases, with oral mucosal involvement in 30% to 60% of cases. This article describes the case study of a 32-year-old woman who presented an extensive tongue ulcer due to histoplasmosis and had the HIV infection diagnosis based on laboratory tests requested by the dentist.
