A Case of Lacrimal Gland Duct Cyst Associated with Ptosis

ABSTRACT

The lacrimal gland ductal cyst is rare, and a closed cyst of the palpebral lobe of the lacrimal gland developing incidiously in the superotemporal cul-de-sac. The authors experienced a case of lacrimal gland ductal cyst, which was a relatively large-sized mass, protruding from the superior temporal conjunctival cul-de-sac. The patient showed temporal blepharoptosis with S-shape of lid margin, but she had no diplopia and limitation of extraocular muscles. The cystic lesion was excised completely through conjunctival approach and lateral canthotomy. Total resection is optimal technique to prevent recurrence. Histopathologically, the cyst contained serous contents in its cavity and its wall was lined by two layers of squamous epithelium, containing some lacrimal gland tissues. This cyst seems to be originated from the palpebral lobe of the lacrimal gland, considering its anatomical location and histopathological findings.
