Intratarsal Keratinous Cyst - An Emerging Entity

Abstract

We report two cases of recurrent intratarsal keratinous cysts of the Meibomian gland, a recently described lesion thought to have been previously misdiagnosed. The correct diagnosis can be made based on histopathologic features alone, although expression of cytokeratin (CK) 5/6 in the cyst epithelium is a specific marker of these lesions. Recognition of these lesions, and distinguishing them from other intratarsal cysts that do not recur, is important to guide definitive therapy via full-thickness excision rather than simple incision and drainage.
