Enterogenous cyst is a benign lesion derived from misplaced endodermal epithelium. We report the aspiration cytology findings of an orbital cyst from a 32-year-old woman. The smears contain benign-appearing cuboidal glandular cells with focal mucinous features. Carcinoembryonic antigen level in the cyst fluid was markedly elevated. These findings are consistent with recurrence of the enterogenous cyst initially diagnosed 7 years earlier.
