摘要：Purpose We report an unusual case of a keratinizing cyst on the lacrimal punctum. Case summary A 49-year-old female presented with an outpouching punctal mass at the left lower lid that occurred a week prior to her visit. Histopathological examination revealed a cyst filled with keratin arranged in lamina and surrounding the bacterial colony. The epithelial wall was composed of multilaminar, keratinizing squamous epithelium without goblet cells. The features were consistent with a keratinizing cyst. There was no recurrence at 4 months after the excision, and the punctum was patent. Conclusions Keratinizing cyst should be considered as a differential diagnosis of the cystic mass of the punctum. Because it has an excellent prognosis after surgical resection, complete resection should be performed if a keratinizing cyst is suspected.
