title: Deep orbital dermoid with draining sinus.
abstract: A dermoid cyst in a 6-year-old girl, deep within the orbit, extended from the apex, through the lateral wall, via a fistulous tract to the skin, forming a draining sinus. Both the deep location and the cutaneous drainage of the cyst are rare presentations of this tumor. We used a Krönlein orbitotomy to successfully remove the tumor without loss of vision.
