A Case of Limbal Dermoid

ABSTRACT

The authors experienced a case of congenitallimbal dermoid, which occured in the right eye in a 30-year-old female. The tumor was noted at birth and grew more rapidly at puberty. The tumor appeared as round yellowish swelling with dry epidermoid surface at the lateral side of limbus about 6 to 8 o'clock position and had a few hairs. The mass was measured 0.8 x 0.5 x 0.4 cm in size. Histologically it was covered by the keratinized stratified squamous epithelium with underlying fibrocollagenous tissue which is embedded by the ectodermal derivatives such as hair follicles, sebaseous and sweat glands. The mass was resected surgically from the limbus for the relief of irritative symptom and cosmetic reason. The case report is reviewed with the pertinent literatures.
