RESUMEN
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.

Soft tissue replacement using a filler as a temporary scaffold to encourage revascularization and tissue in growth is an exciting concept. Sheets of acellular human dermal matrix, called Alloderm (Lifecell Corp, Branchburg, NJ), have been shown to do just that. When implanted into a patient, tissue growth and revascularization have both been observed. The company manufactures a micronized or injectable form called Cymetra. This article reviews the manufacturing, tissue interaction, clinical applications, and anticipated clinical results.
