Acquired immunodeficiency syndrome. A report of 2 South African cases.

This report documents the first 2 cases of the acquired immunodeficiency syndrome in male homosexuals identified in South Africa. Both patients died of Pneumocystis carinii pneumonia and both had cytomegalovirus infection. Neither had peripheral lymphadenopathy and in both cases the lymph nodes showed cortical and paracortical atrophy with marked plasma cell and histiocytic infiltration. It is suggested that this lymph node pattern represents the morphological expression of the immunological defect in this syndrome.
