Pleomorphic Adenoma of the Lacrimal Gland in a Child

Purpose: To report one case of pleomorphic adenoma of the lacrimal gland in a child. Case summary: A 7-year-old boy presented with a 2-month history of an exophthalmos and mild ptosis of the left eye; there were no other ophthalmologic problems. Orbit MRI revealed a well-defined mass in the left lacrimal gland and a defect in the orbital roof due to pressure erosion. Tumor resection was performed via a lateral orbitotomy and a biopsy was requested. The biopsy revealed tumor tissue that was composed of epithelial elements with variably sized duct formation. Focal squamous metaplasia and keratin production was also observed. Conclusions: Pleomorphic adenoma of the lacrimal gland should be considered as a differential diagnosis of a lacrimal gland mass in a child. J Korean Ophthalmol Soc 2014;55(3):422-425
