Role of fine-needle aspiration cytology in diagnosis of disseminated histoplasmosis in an immunocompetent patient: A case report.

Histoplasmosis is a mycotic infection caused by dimorphic fungus, Histoplasma capsulatum. The organisms are usually found within the cells (macrophages). This organism mostly affects lungs in immunocompetent individuals and disseminated forms are seen in immunocompromised cases. Here, we describe a case of disseminated histoplasmosis in an immunocompetent, 35-year-old female with lymphadenopathy diagnosed by fine-needle aspiration cytology and cell block.
