A Case of Scar Sarcoidosis of The Eyelid

Purpose: We report the case of a patient with scar sarcoidosis that developed along a previous eyelid scar. There was no evidence of ocular or systemic sarcoidosis. Methods: A 29-year-old man presented with a mass on his right eyelid that had been present for two month. On ocular examination an erythematous, firm, and non-tender mass was diffusely palpable along the upper and lower eyelid scar. We performed an incisional biopsy of the lower lid mass. Results: Histopathologic examination of the mass revealed numerous, noncaseating granulomas with multi-nucleated giant cells. The giant cells contained asteroid bodies and calcium oxalate crystals characteristic of sarcoidosis, although the patient had no other evidence of systemic sarcoidosis. The mass in the upper lid disappeared after intralesional triamcinolone injections. Conclusions: This case represents a rare occurrence of sarcoidosis that arose in an old eyelid scar. Scar sarcoidosis should be considered in the differential diagnosis of an unusual mass in a scar. Korean Journal of Ophthalmology 20(4):238-240, 2006
