Multilobular dermoid cyst of the orbit

ABSTRACT

Dermoid cysts are histologically defined as surface epithelium encapsulating an inner lumen. They are well described in the literature as discrete, single masses, either circumscribed or dumbbell-shaped, with or without a longstanding fistula. Chronic granulomatous inflammation is often a feature of dermoid cysts, contributing to local soft tissue and bony destruction. Isolated multicystic dermoids are not well described. We present a case of a multilobular dermoid characterized both radiographically and histopathologically. These findings may be attributed to repeated rupture and reformation of the dermoid cyst. When possible, our experience favours early excision of orbital dermoid cysts to minimize morbidity.
