Acquired immune deficiency syndrome (AIDS) in Brazil. Necropsy findings.

According to the 15 autopsies performed at the Department of Pathological Anatomy, Escola Paulista de Medicina, São Paulo, Brazil, it was confirmed that acquired immunodeficiency syndrome (AIDS) occurs preferably in young homosexual males, who die in a short period of time of the disease, which leads to a consumptive state verified by cachexia of the cadavers. The most affected organs of this series were the lungs and encephalum, exactly the ones responsible for the immediate cause of death. In this series of autopsies there were 9 types of microorganisms represented by virus, bacteria, fungi, protozoans and two types of tumors, Kaposi's sarcoma and lymphoma of the central nervous system.
