Disseminated histoplasmosis leading to end stage liver failure in immunocompetent patient: case report and review of literature.

Abstract

Histoplasmosis is the fungal infection caused by Histoplasma capsulatum fungus. It is commonly found in a few endemic areas in the United States, where there is a large number of birds or bats and can spread through their droppings. Disseminated histoplasmosis is a severe manifestation of the fungal infection which is commonly seen in individuals with underlying immunosuppression. Our case is an unusual case of disseminated histoplasmosis in a 60-year-old, immunocompetent male patient with a history of significant alcohol abuse, which led to end stage liver failure. While the patient showed some signs of improvement initially upon beginning the treatment, he ultimately continued to deteriorate despite treatment due to an overwhelming histoplasmosis infection. This case demonstrates the importance of keeping a high index of suspicion even amongst immunocompetent patients with no obvious exposure to risk factors. It also shows that timely diagnosis with a high index of suspicion is required with an integrated treatment approach.
