Disseminated histoplasmosis in an HIV/AIDS transgender male-to-female with atypical and persistent GI manifestations.

Disseminated histoplasmosis is a rare complication of infection due to Histoplasma capsulatum . Typically, histoplasmosis is self-limiting and asymptomatic in infected individuals with immunocompetence. Disseminated disease, however, can arise in high-risk populations with primary or acquired cellular immunodeficiency including HIV/AIDS, transplant recipients, and those undergoing immunosuppressive therapy. Here we describe a unique case of extrapulmonary gastrointestinal histoplasmosis by infiltrative Peyer's patch disease with bone marrow involvement in a transgender HIV-infected woman.
