DIFFERENTIATING ASTROCYTIC HAMARTOMA FROM MALIGNANT MELANOMA

Blair Lonsberry

Abstract

BACKGROUND: Malignant melanoma of the choroid is the most common primary intraocular tumor. With their high propensity to metastasize, it is crucial that timely and accurate diagnoses are made of any suspicious lesions in the eye.

CASE REPORT(S). The following patient presented to the eye clinic for a routine eye exam, at which time a pigmented lesion was noted in the superior-temporal quadrant of her left eye. The lesion was categorized as a choroidal nevus, and follow up dilated fundus exams were scheduled every three months. Upon her second follow up visit, there was a question of elevation to the lesion, so a fluorescein angiography was performed which demonstrated choroidal folds surrounding the lesion. An ophthalmological consult was obtained, and the lesion was ultimately determined to be an astrocytic hamartoma.

CONCLUSIONS. This presentation will present color photographs, fluorescein angiography and ultrasonography of our presenting patient, and discuss the differentials that need to be considered in excluding a potentially fatal malignant melanoma.
