Case #325 – June, 2012

A 26-year-old man was seen by his health care provider for the sensation of something moving in his mouth. He reported a history of such sensations since he was age 12. He was referred to an otolaryngologist who observed a serpentine-like lesion, with possible movement, in the lateral left soft palate. A worm-like structure was removed surgically and sent to the DPDx Team for identification. Figure A shows a gross image of the entire worm. Figures B and C show the anterior and posterior ends, respectively, and were captured at 100x magnification. Figure D shows the mid-section, captured at 200x magnification. What is your diagnosis? Based on what criteria?
