Abstract

An unusual case of black heterotopic orbital bone is described. We are unable to find a similar account of osseous pigmentation in the ophthalmic or systemic literature. A variety of special studies suggested that the pigment was an oxidation-polymerization product such as melanin, oxidized epinephrine, or oxidized tetracycline. Various possibilities concerning the histogenesis of the pigmented bone are considered.
