Disseminated histoplasmosis and tuberculosis: dual infection in a non-endemic region.

BMJ Case Rep 2020 Aug 24;13(8). Epub 2020 Aug 24.

Department of General Medicine, Government Medical College and Hospital, Chandigarh, India.

Histoplasmosis is a systemic fungal infection caused by a dimorphic fungus that spreads commonly by contamination of soil with bird and bat droppings. The infection remains latent in most patients until manifested by reduced immune status, for example, HIV/AIDS, corticosteroid/immunosuppressive therapy or in solid organ transplant recipients. Tuberculosis and histoplasmosis may cooccur rarely in HIV and the clinical resemblance of both diseases may hinder identification of patients' harbouring dual infection, especially in regions non-endemic for histoplasmosis.
