title: Osseous metaplasia of the eyelid: report of 2 cases.
abstract: This article describes 2 unusual cases of osseous metaplasia occurring within the eyelid and presents a brief review of the literature on cutaneous calcification. A 62-year-old man sought treatment for an eyelid mass containing osseous metaplasia in an area of lymphoid hyperplasia. An extensive oncologic workup ruled out malignancy. A 46-year-old man with a history of recurrent chalazion sought treatment for a firm mass of the upper eyelid that demonstrated bone formation in an area of sebaceous glands. Both lesions were excised with no further recurrence. Osseous metaplasia of the eyelid is a rare entity with diverse etiologies ranging from congenital syndromes to trauma, neoplasm, and inflammation. In some cases, a precise etiology cannot be identified.
