A Case of Disseminated Histoplasmosis From California, in the Setting of Secondary Hemophagocytic Lymphohistiocytosis: A Diagnostic Challenge

Abstract

Histoplasma capsulatum is a geographically specific dimorphic fungus that can cause a spectrum of diseases. While most cases are asymptomatic pulmonary infections, in severe cases, particularly in immunocompromised patients, disseminated disease can occur. Histoplasmosis in California is limited to only a few case reports. In this article, we describe a rare case of disseminated histoplasmosis in a non-endemic region presenting with diagnostically challenging symptomatology, including altered mental status, status epilepticus, septic shock, and bilateral adrenal masses.
