title: Zoonotic anatrichosomiasis in an Illinois resident.
abstract: We describe a case of zoonotic anatrichosomiasis in a patient from Illinois. A 44-year-old immigrant from Mexico originally presented with a history of multiple oral ulcers and two submucosal nodules on the dorsal surface of the tongue. An incisional biopsy was taken to assist with diagnosis. Examination of stained sections revealed the presence of a coiled nematode. The histologic examination displayed trichuroid features. Anatomic structures that aided in the identification included esophagus embedded in a prominent stichosome in the anterior end, paired bacillary bands, and small size. The location of the worm within the oral mucosal epithelium also facilitated the diagnosis.
