Keratin pearl cyst formation after traumatic implantation of an eyelash into the anterior chamber: A case report.

ABSTRACT

Purpose: We introduce a case with creamy white pearl-like keratin cysts in the anterior chamber after a penetrating injury associated with eyelash implantation. Observations A 5-year-old girl presented with a history of penetrating corneal injury with a knife ten months ago. An eyelash was removed from the anterior chamber during her previous primary repair. Her parents complained about the presence of a white mass in her repaired eye, which had appeared about nine months after surgery. After the visco-expression of these solid masses, the histopathological evaluation revealed keratinous material surrounded by multinucleated giant cells. Conclusions and importance In a case of post-traumatic implantation of eyelash into the anterior chamber, despite removing the cilia, cysts may develop, which suggests proliferating epithelial cells embedded within the anterior chamber.
