Pleomorphic adenomas of the lower eyelid: a case series.

ABSTRACT

Pleomorphic adenomas are well-recognized tumors usually arising within the main lacrimal gland. Their occurrence, however, is not limited to the main lacrimal gland. There have been cases reported in the eyebrow, upper eyelid, lateral lower eyelid, lacrimal sac, and even intraocularly. The medial aspect of the lower eyelid is a very rare site of occurrence because it is largely devoid of accessory lacrimal glands. We describe 2 cases of pleomorphic adenomas arising in the medial aspect and 1 case arising in the middle of the lower eyelid, respectively. The likely origin of these tumors at this location is from ectopic lacrimal gland.
