Dacryops of the lacrimal gland in an elderly woman: A case report.

Dacryops is a rare benign cystic lesion of the lacrimal gland often developing in the palpebral gland. The exact etiology of dacryops remains unclear. Diagnosis could be suspected clinically and established histopathologically. Treatment is commonly surgical. We report the case of a 75-year-old woman with past history of total conservative parotidectomy for a benign tumor 10 years ago. She presented to the Ophtalmology Department at Farhat Hached University Hospital of Sousse with a painful swelling of the left supero-external orbital angle. The patient underwent complete excision of the cyst using the conjunctival approach. Histopathological examination showed characteristic features of dacryops with foci of chronic inflammatory cell infiltrates. Dacryops is commonly seen in young adults or middle-aged individuals with a slight female preponderance. In some cases, cystic enlargement of dacryops can lead to mechanical ptosis, dystopia, limitation of extraocular movements, diplopia, and, in rare cases, blepharoptosis. However in this case, the patient was an elderly woman presenting a painless mass without ptosis. As in our case, excision using the conjunctival approach under microscope has excellent results without complications. Histopathological examination confirms the diagnosis and helps to rule out differential diagnoses. As reported in the present case, histopathological examination confirms clinically recognized or suspected dacryops. If untreated, dacryops may lead to ptosis, proptosis and/or dystopia. Complete excision of the cyst is often curative.
