Xanthomas are nodular masses of lipid-laden histiocytes which may contain scattered Touton giant cells. They occur in the systemic lipoidoses, in patients with increased serum lipids, and in apparently normal individuals. These lesions may be solitary or may be seen as multiple plaques or papules with a characteristic distribution.
The ophthalmologist encounters this abnormality most frequently as the xanthelasma palpebrarum. The present report describes a patient with xanthomata involving the conjunctivae. A review of the literature and of cases on file at the Registry of Ophthalmic Pathology indicate this to be an extremely unusual site. The lesion had the appearance of fibrous xanthoma, a type that may be less benign than other types of xanthoma.
