Abstract:
Intestinal Schistosomiasis is a serious disease and is commonly produced by S. mansoni and japonicum. The presence of viable ova of the organism in the colon elicits inflammation, formation of granuloma, ulcers, haemorrhage and colonic fibrosis with subsequent longterm sequelae. Schistosoma mansoni is endemic in the Middle East, Africa, Central and South America. This is a case of a Nigerian with colonic polypoid masses which turned out to be Schistosomal mansoni infection.
