Case #248 – March, 2009

A 36-year-old immigrant from Mozambique presented to his health care provider with heartburn and chronic right abdominal pain. All previous ova and parasite (O&P) examinations were negative. An endoscopy was performed, upon which a worm-like object was observed in the ascending colon near the ileocecum. The suspicious object, measuring approximately 7 mm in length, was removed, collected in 10% formalin, and sent to Pathology for work-up. The object was sectioned, stained with hematoxylin and eosin (H&E) and reviewed by the attending pathologist, who in turn captured the following images and sent them to DPDx for telediagnosis assistance.
