Esophageal schistosomiasis in a patient with megaesophagus

The authors report a case of schistosomiasis of uncommon location. A patient submitted to esophagectomy for Chagas' megaesophagus was found to have eggs of Schistosoma mansoni upon pathologic examination of the surgical specimen. The authors discuss the anatomopathological aspects of schistosomiasis, as well as its occurrence in other rare sites. To date, no references in literature have been found on the existence of esophageal schistosomiasis, and its association to Chagas' megaesophagus has never been described.
