Rectosigmoid bilharzioma causing intestinal obstruction

Schistosomiasis is an infection caused by flukes (trematodes) of any species of the genus Schistosoma whereas bilharzioma implies a localized mass of fibrous and inflammatory tissue, which usually contains many eggs, frequently involving serosa and mesentery. Bilharziomas are probably caused by a reaction to numerous eggs produced by one or more pair of worms in a single site, although altered host reactivity may also be a factor. Bilharziomas, even in endemic areas are quite uncommon lesions in adults. So far they have not been reported to cause intestinal obstruction in children. Herein we present a case masquerading as large bowel malignancy in a child. Management and follow up are also mentioned.
