ABSTRACT
PURPOSE: Lacrimal gland duct cysts constitute a rare clinical entity and may be preceded by trauma, infection, or inflammation without antecedent history. The purpose of this study is to report one case of lacrimal gland duct cyst accompanied by a dacryolith. METHODS: A 41-year-old man presented with sudden enlarging mass in the left superotemporal conjunctival fornix 3 days ago. The lesion was about 10 X 10 mm in size. There was no tenderness or erythema in adjacent area. The CT scan was done and excisional biopsy was performed under local anesthesia. RESULTS: Specimen consisted of cystic membranous tissue in 9.0 X 7.0 mm in size and mucous material and a light brown dacryolith of 1mm in diameter within cyst. Specimen included normal lacrimal tissue. Microscopic examination found cyst was covered with stratified columnal epithelium accompanied by acute and chronic inflammation and eosinophilic acellular dacryolith mixed with inflammatory exudates. There was no bacterial colony and polarizing microscope found no birefringence. CONCLUSIONS: Such case of a eosinophilic dacryolith within lacrimal gland duct cyst has never been reported at home and abroad.
