Anterior segment optical coherence tomography findings in epibulbar choristomas: Case Series

Epibulbar choristomas are benign congenital ocular tumors characterized by abnormal growth in the epibulbar tissue, eyelids, and choroids. Two cases of epibulbar choristomas are described; the first one is a 39-year-old woman who presented a temporally conjunctival mass that had progressed in size accompanied by foreign body sensation and epiphora. Optical coherence tomography (OCT) and surgical resection were performed with a histopathological diagnosis of dermolipoma. The second case is a 7-year-old boy with a congenital corneal lesion in the nasal sector, elevated, vascularized, and with decreased visual acuity. In both cases, OCT showed a thinned epithelium with hyporeflective subepithelial fusiform lesions. OCT is an auxiliary method for the diagnosis of conjunctival lesions, such as epibulbar choristomas.
