Info

Right conjunctival epibulbar small lesion of fat density. It is smoothly abutting the related lateral aspect of the globe. No connection to the intra-orbital fat.

Case Discussion

Dermolipoma is one of the fat-containing epibulbar mass lesions of lateral canthal area beneath the temporal or superotemporal bulbar conjunctivae. This should be differentiated from subconjunctival fat prolapse as they have different radiological features and  treatment strategies. Dermolipomas are congenital and more commonly seen in young patients in contrast to the subconjunctival fat prolapse which occurs in old age. Also, dermolipoma usually has no connection to the intra-orbital fat, unlike subconjunctival fat prolapse.
