Boston keratoprosthesis type 2 is used to treat severe corneal blindness secondary to cicatricial or autoimmune ocular surface disease. This case report describes an atypical eyelid mass in a 41-year-old woman with Stevens-Johnson syndrome who underwent placement of Boston keratoprosthesis type 2 in the left eye. The postoperative course was complicated by methicillin-sensitive Staphylococcus aureus keratitis and endophthalmitis requiring replacement of the keratoprosthesis. Three months thereafter, the patient presented with a progressively enlarging upper eyelid mass adjacent to the keratoprosthesis optic causing distortion of the eyelid. Excisional biopsy revealed an elongated cystic mass abutting the superior aspect of the optic. Pathologic examination was consistent with a conjunctival cyst with lipogranulomatous reaction. Removal of eyelid margins and conjunctiva, and placement of a full-thickness blepharotomy are standard steps in placement of Boston keratoprosthesis type 2, which can lead to conjunctival cysts and lipogranulomas that present as eyelid masses.
