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 disease progresses rapidly and death occurs in about 90% of cases.

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.
