Squamous cell carcinoma of the conjunctiva associated with benign mucous membrane pemphigoid.

A 67-year-old white man with benign mucous membrane pemphigoid OU developed, over a period of two months, a slightly pedunculated fleshy mass in the bulbar conjunctiva OS. The mass was excised and found histopathologically to be squamous cell carcinoma of the conjunctiva. The association of benign mucous membrane pemphigoid and squamous cell carcinoma of the conjunctiva has not been previously reported in the English literature to our knowledge. The significance of the simultaneous occurrence of these two conditions is discussed.
