A 7-year-old boy presented with a 2-month history of nonresolving redness and itching in the left eye. The slitlamp biomicroscopic examination results of the left eye revealed a well-defined, 6 mm × 5-mm yellowish-pink epibulbar mass with overlying blood vessels (Figure, A). It was located in the superotemporal quadrant (10 mm from the limbus) and was nontender, hard, and immobile on palpation. The ultrasonography biomicroscopy results showed an episcleral, hyperechoic lesion with posterior acoustic shadowing. The computed tomography results of the orbits showed a focal hyperdensity over the left temporal scleral coat. Surgical excision was performed and an ivory white, shiny mature tooth (Figure, B) was removed along with its surrounding capsule. The underlying sclera appeared normal, and the histopathology results showed a fibrocollagenous cyst wall with a denuded lining epithelium and foci of calcification. Based on the clinicoradiological findings and histopathology results, a final diagnosis of the epibulbar dermoid cyst with a tooth was made.
