Solitary xanthoma of the limbus.

Abstract

An Ix-year-old Caucasian boy was seen at the Indiana University Medical Center, Department of Ophthalmology, because of a yellow limbal lesion of the left eye which had been first noted 2 years previously, and which had been progressively enlarging. The family history was not contributory. The child was premature, but developed normally with no history of significant systemic or ocular disease. There was no history of ocular trauma. The general physical examination was within normal limits. Specifically, no dermatological sign of xanthoma formation was found and hepato-splenomegaly was not present. The visual acuity was 20/20 in the right eye and 20/70 in the left. The yellowish, raised mass measured 6 x 7 mm. in diameter at the medial limbus and encroached upon the pupillary area (Fig. I). Several large trunk vessels penetrated the mass. Thin needlelike, multicoloured crystals were noted in the mid-stroma of the cornea bordering the advancing edge of the lesion.
