Abstract
BACKGROUND AND OBJECTIVES: Accessory lacrimal gland ductal cyst is a rare clinical entity that has been reported after trauma, infection, or conjunctival inflammation. Trachoma has been postulated as an etiologic factor for this dacryops in Saudis. We studied the prevalence, demographics, clinicopathological features and surgical approach for these lesions.
DESIGN AND SETING: Retrospective study of 23 consecutive ductal cysts diagnosed clinically and proved histopathologically at King Khaled Eye Specialist Hospital (KKESH) over 23 years (1991-2014).
PATIENTS AND METHODS: Data on patient demographics, clinical features, surgery, and outcome were collected by chart review. The histopathologic slides were reviewed by a single pathologist.
RESULTS: Of 23 cases of accessory lacrimal gland ductal cysts confirmed histopathologically, 14 were males and 9 females with a median age of 38.8 years. Cysts were located in the upper eyelid in 73.9%. The commonest presentation was a painless eyelid mass in 91.3%. Excision by conjunctival incision was performed in 14 and intra-operative perforation occurred in 9. Trachomatous scarring was evident in 39.1% but did not have significance in relation to this rupture. No recurrences have been observed with a mean follow up of 34.6 months.
CONCLUSION: The approximate prevalence of accessory lacrimal gland dacryops in the Saudi population is 1/6800. Trachoma does not seem to be a major predisposing factor. They are more frequent in males. Their histopathological appearance is identical regardless of origin. The presence of conjunctival scarring, dacryops size, and the surgical incision type did not seem to have significant correlation with the iatrogenic rupture of the cyst. We recommend careful dissection for complete cyst excision through conjunctival approach with no expected recurrence.
