Histoplasmosis

Ohio River Valley fever; Fibrosing mediastinitis

Histoplasmosis is an infection that occurs from breathing in the spores of the fungus Histoplasma capsulatum.

Lungs

The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.

Acute histoplasmosis

Histoplasmosis is a fungal infection caused by inhaling dust from spore-infected bird droppings. The acute form is treated with antifungal medication.

Disseminated histoplasmosis

Histoplasmosis is a fungal infection caused by inhaling dust from spore-infected bird droppings. In the disseminated form, infection spreads throughout the body from the lungs. The death rate is fairly high for people with untreated widespread (disseminated) histoplasmosis, but is reduced significantly with treatment.

Histoplasmosis, disseminated in HIV patient

This is a skin lesion resulting from disseminated histoplasmosis. Histoplasmosis occurs most frequently as a lung infection, however it can infect the skin or become distributed (disseminated) to internal organs.
