Sebaceous Adenocarcinoma Combined with Squamous Cell Carcinoma on the Upper Tarsal Conjunctiva

ABSTRACT

Sebaceous adenocarcinoma and squamous cell carcinoma of the conjunctiva are relatively uncommon diseases which usually develop in the upper eyelid and limbus. They spread to the adjacent bulbar and tarsal conjunctiva, cornea and sclera but their intraocular invasions are very rare. In our country, sebaceous adenocarcinoma or squamous cell carcinoma which occurred independently was reported, but no case of sebaceous aoenocarcinoma combined with squamous cell carcinoma of the conjunctiva was reported. We experienced a case of tumor at right upper tarsal conjunctiva in a 76-year-old Korean woman. Histopathologic examination revealed sebaceous adenocarcinoma combined with moderately differentiated squamous cell carcinoma.
