Figure 1.

A, Gongylonema pulchrum embedded in the lip mucosa of the patient. Arrowhead denotes location of living worm. B, Higher magnification of the same specimen, also in situ, in the lip mucosa. C, Anterior end of the specimen, showing rows of diagnostic bosses. D, Intact worm. E, Polymerase chain reaction fragments amplified from genomic DNA isolated from midbody of the worm shown in A–D for the mitochondrial cytochrome c oxidase subunit 1 (cox-1) gene and ribosomal RNA gene subunits 18S, 5.8S, and 28S (lanes 1–4) and subcloned and sequenced to genetically validate the worm as Gongylonema pulchrum. DNA ladder is indicated in basepairs (bp). Scale bar in A = 3 mm, scale bar in B = 1 mm, and scale bars in C–D = 0.1 mm.
