title: Appendicitis and schistosomiasis.
abstract: A retrospective clinical and pathological study of 15 cases associated with schistosomiasis drawn from 1920 patients undergoing appendicectomy is discussed. The average age of the patients was 31.6 years with a 12:3 male predominance. Hepatomegaly, past or present jaundice, or splenomegaly were not observed. One patient had a previous history of similar right lower quadrant pain for several days. Eighty per cent of the cases showed an inflammatory reaction on pathological examination. In the remaining 20 per cent no inflammation was seen, but there was severe congestion mainly involving the subserosal blood vessels. Schistosoma haematobium was present in 80 per cent of the cases.
