A 24-year-old male Egyptian complained of cramp-like upper abdominal discomfort and weight loss (3 kg) over 4 weeks. Physical examination merely gave evidence of the weight loss and of a slightly prominent gas-filled abdomen, mild diffuse abdominal tenderness and considerable borborygmus. Radiology of the intestines revealed chronic subileus of the small intestine caused by stenosis of the ileocaecal valve, which was impassable by coloscope. Biopsy suggested schistosomiasis of the ileocaecal valve. Examination of the resected ileocaecum showed a typical signet-ring carcinoma of the ileocaecal valve which had infiltrated all layers but had not metastasised to the regional lymph nodes (pT3, N0, M0). Typical eggs of Schistosoma haematobium were present in the mucosa of the tumour segment and of the neighbouring tissues. It is possible that chronic intestinal schistosomiasis is a potentially precancerous condition, similar to schistosomiasis of the urinary bladder.
