Benign pleomorphic adenoma arising from the palpebral lobe of the lacrimal gland associated with elevated intraocular pressure.

A 46-year-old man complained of a painless mass in the left upper eyelid. At age 51 years, the patient complained of dull pain in the left eye and diplopia. His left intraocular pressure had increased to 33 mm Hg. No proptosis was noted. The nontender mass in the eyelid was palpable. Computed tomography showed a mass anterior to the orbital rim compressing the globe. The lesion was removed en bloc by a transconjunctival approach. Histopathologic examination of the excised mass showed myxomatous stroma and highly cellular epithelial areas. Postoperatively, the left intraocular pressure normalized. To our knowledge, benign pleomorphic adenomas arising from the palpebral lobe of the lacrimal gland associated with elevated intraocular pressure, as demonstrated in our patient, may be rare.
