Schistosomiasis is a parasitic trematode infection spread by snails with multiple species causing human disease. Infection can cause liver disease, including fibrosis and portal hypertension, and has been linked to malignancies such as bladder and colorectal cancer. We describe a case of Schistosoma mekongi, a geographically limited form of schistosomiasis, in a Laotian immigrant who presented with both hepatic fibrosis and rectal cancer, with numerous schistosome eggs present in the patient’s rectal resection. We believe this case is the first report of a rectal carcinoma arising in the setting of S. mekongi infection.
