Invasive squamous cell carcinoma of the conjunctiva.

A 75-year-old man, known with Morbus Kahler, was referred with a history of uveitis and hypopyon at the left eye. The uveitis did not respond to any steroid treatment. It was complicated with high intraocular pressure. Anterior chamber punction showed atypical cells of epithelial origin. Several weeks prior to this presentation an atypical pterygium of the same eye was biopsied. Histopathologic examination at that time showed mild atypical actinic changes. The biopsy specimen was reviewed in our laboratory and revealed an invasive squamous cell carcinoma originating from the bulbar conjunctiva. The eye was eventually enucleated. Histologic examination of the enucleated eye showed invasion of the cornea, sclera, trabeculum, anterior chamber angle and choroid by a muco-epidermoid squamous cell carcinoma.
