Colonoscopy Reveals Living Cockroach in Patient’s Colon

“A 52-year-old woman with a history of depression was referred by her  primary physician for colorectal cancer screening. She had no family  history of colorectal cancer and a review of systems was positive for  abdominal bloating. Bowel preparation was done using 4 L of polyethylene  glycol the evening prior to screening colonoscopy. The procedure was  uncomplicated with no gross mucosal pathology, however, an insect was  found in the transverse colon (Fig. 1, to the left), was found in the transverse colon on a routine screening colonoscopy.). The insect was aspirated and sent to the lab for further identification. The insect had three body segments (head, thorax, and abdomen) with ventrodorsal flattening of the body and a segmented abdomen, three pairs of legs extending from the thorax (with spikes and claw-like terminal appendages), elongated hind legs, and a pair of elongated antennae extending from the head to beyond the hind legs.These morphologic findings were most consistent with the nymph form of Blattella germanica (German cockroach) of the Blattellidae family, a common household pest. The patient had a cockroach infestation at home and hence it was hypothesized that she may have inadvertently ingested a cockroach with food.”
