CLINICOPATHOLOGIC REPORT Retinal Hamartoma in Oral-Facial-Digital Syndrome

Patricia S. Tsai, BS; Joan M. O’Brien, MD

nly recently have intraocular findings been described in oral-facial-digital syndrome (OFDS), including 5 cases of chorioretinal and 1 case of optic nerve colo- boma. We report a case of a new ocular anomaly associated with this syndrome: a retinal hamartoma in a male infant with OFDS. The patient had bilateral retinal masses Othat were suspicious for because of a family history of retinoblastoma. Physical ex- amination and imaging studies of the retinal masses could not differentiate between retinoblas- toma, hamartoma, or persistent hyperplastic primary vitreous. Subsequent pathologic study of an enucleated was diagnostic of a retinal hamartoma. This case further illustrates the hetero- geneity of ocular anomalies in OFDS and underscores the importance of a complete ophthalmo- logic evaluation in patients with this syndrome.
