[Histopathologic changes in several opportunistic infections in AIDS]

Opportunistic infections are frequent in AIDS patients, particularly in the last phase of the disease, when they occur both singly and in combination with other conditions (for example KAPOSI's sarcoma). These opportunistic infections are the cause of death in over 90% of cases. Their incidence ist proof of cellular immunodeficiency. Based on our observations (17 cases at the two institutes since 1984) we present and discuss the histopathological changes of some important opportunistic infections (notably Pneumocystis carinii pneumonia, Mycobacteriosis (MAI), Cryptosporidium Cytomegalovirus and Toxoplasmosis gondii infection).
