“…They are cysts of developmental origin and histologically characterized with squamous cell lining, keratinoid or mucoid content, occasionally associated with fatty component and calcified structure (Nishie et al., 2003). In humans, the commonest choristomatous cyst of the orbit is dermoid cyst, which is usually lined by keratinizing squamous epithelium (West et al., 1997). The orbital area is one of the most common sites for dermoid cysts (McCollough et al., 1991).…”

Clinical and histopathological findings of a congenital ocular dermoid cyst, located at the lower eyelid of a river female buffalo (Bubalus bubalis) calf were presented. A soft, fluctuant, non-tender, hyperaemic cystic mass was detected overlaying the left eye. Fine needle aspirate revealed filamentous debris with no malignant cells. The cyst was treated surgically by orbital exenteration and subsequently subjected to histopathological examination. The histopathological study disclosed a conjunctival dermoid cyst. This report is novel, in that; such ocular cyst has not previously been described in river buffalo calves.

Congenital or post-traumatic respiratory epithelial lined cysts of the orbit are very rare, and such cysts more commonly occur as mucocoeles secondary to chronic paranasal sinus disease. Four new cases of such cysts are described herein, three presumed choristomas and one occurring after trauma. Two of three presumed choristomatous (congenital) cysts occurred in sites that were atypical for the commoner dermoid cyst. One occurred in the superior orbit between the superior rectus and levator palpebrae superioris muscle and one in the temporal fossa and lateral orbit. The third choristomatous lesion occurred in the superotemporal orbit with a well-defined bony defect, a typical pattern of the commoner dermoid cyst. The fourth case, a presumed traumatic respiratory epithelial cyst, probably arose from ethmoidal sinus mucosa. Respiratory epithelial orbital cysts are very rare and may occur in sites that are atypical for the commoner orbital dermoid cyst.
