Erythroplasia of Queyrat (EQ) is an epidermoid carcinoma in situ which is histologically identical with Bowen's disease of the skin but involves mucosal surfaces. The lesion is known to occur on the glans penis, the vulva, and the oral mucosa. Two cases of EQ of the conjunctiva that developed several years after radiotherapy for basal cell carcinoma of the eyelids are here reported. The signs and symptoms closely mimicked those of chronic conjunctivitis. The lesions were excised by the microscopically controlled excision of Mohs. It is recommended that biopsy material be obtained in patients who develop a nonresolving chronic conjunctivitis, especially when there is history of radiotherapy of the eyelids.
