Case #437 - February, 2017
A 31-year-old female, with travel to Mexico a few months prior, noticed a small worm-like object on the inner surface of her lower lip. She removed the object with a needle and delivered it to her health care provider. The object was forwarded to the CDC DPDx Team for identification. Figures A and B were taken with a dissecting microscope and the ruler in the background shows one centimeter; Figure C is a composite of two images of the organism that was submitted taken with a compound microscope to show the entire organism at 40x magnification. The insert (of the anterior end) was taken at 100x magnification. What is your diagnosis? Based on what criteria?
