decoy cell

A small, atypical exfoliated urothelial cell that mimics carcinoma-in-situ of the bladder, which is often caused by human polyoma virus. Decoy cells have single, large, homogenous, basophilic inclusions occupying most of an enlarged nuclear area; other cytologic findings of polyomavirus infection include “empty cells” (post-inclusion stage) and “comet cells”.
