Keratoacanthoma of the Eye Lid

ABSTRACT

Keratoacanthoma is important because it is frequently mistaken, both clinically and histologically, for basal-call or squamous-cell carcinoma. The usual clinical picture is that of a rapidly enlarging, nodular, umbilicated lesion occurring more often in the lower eye lid. A keratoacanthoma sometimes merges into a carcinoma and is misdiagnosed histologically, therefore cases originally diagnosed as keratoacanthoma should be closely followed. A 64-year-old Korean woman was found to have a small enlarging, umbilicated tumor in right lower lid which was recurred in 3 months after removal of tumor under the diagnosis of squamous cell carcinoma in some hospital. In our hospital, the tumor was removed under local anesthesia and found to be keratoacanthoma histopathologically.
