A 46-year-old female patient presented with left proptosis and headache. A radiological study revealed a large, cystic, bilobed mass in the orbital-temporal area with an osseous defect in the lateral wall. A histological examination of the excised lesion showed that the cyst wall consisted of non-keratinized stratified epithelium with goblet cells. There was no recurrence during the follow-up. Of the previously reported 54 cases, only 1 had bone erosion due to a recurrent cyst in the frontal bone. Although rare, a primary conjunctival cyst can create a dumbbell-shaped lesion in the lateral orbit and temporal fossa.eninfo:eu-repo/semantics/closedAccessDermoid cystsScience & technologyLife sciences & biomedicineOphthalmologySurgeryArticle000970974000007E50E5239210.1097/IOP.0000000000002311
