Abstract
Angular dermoid cysts are common periorbital tumours in children. They are tumours of embryonic origin that arise along bony sutures as a result of abnormal ectodermal sequestration during development. Angular dermoid cysts usually present in early childhood, are characteristically small benign and slow growing lesion. External angular dermoid present in the superotemporal quadrant is more common compared to internal angular dermoid in the superonasal quadrant. Early surgical excision is recommended and performed in the majority of cases, particularly to restore facial cosmesis.
Here we report an unusual case of a large internal angular dermoid cyst indenting the globe in a 3-year-old girl presented with left upper eyelid mass at medial angle since one year of age. The cyst was excised completely by anterior orbitotomy through a small superior lid crease incision.
Keywords: Dermoid cyst, angular dermoid cyst, internal angular dermoid, superior eyelid crease incision.
