Ectopic lacrimal gland cyst of the orbit. 1981

A Rush, and C R Leone

Ectopic lacrimal gland tissue is most common in the eyelid, conjunctiva, and cornea, but may also be found in the uvea or orbit. A 7-year-old boy developed a mass in the anterior superiomedial orbit close to the trochlea. A superior medial orbitotomy, done when the boy was 9 years old, disclosed a tense, thin-walled, fluid-filled cyst containing a small nest of normal lacrimal gland with a large capsule of fibrous tissue containing areas of singly layered epithelial cells.
