Abstract
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.

The keratinizing cyst of the left lower lid. (A) A photograph of the left lower eyelid showing a 2 mm, tense, whitish, non-vascular, smooth, cystic, dome-shaped mass at the region of lower punctum. (B) The epithelium was multilayered and showed a regular basaloid germinal layer without any goblet cells or any granular layer. Microphotograph showed keratin fibers on the stratified squamous epithelium (Haemotoxylin and Eosin [H&E] stain, ×400). (C) Microphotograph of the cystic content showing central bacterial colony (arrow) and surrounding keratin fibers arranged in laminar and wavy patterns (H&E stain, ×40). (D) There was no recurrence after 4 months.
