We present six cases (five females, one male; aged 26–81 years) of dacryops, also known as lacrimal gland cyst, all of which occurred at the outer canthal area below the upper eyelid. All presented clinically as a painless cystic lesion that was white to blue in color. Microscopically, in addition to typical features of dacryops, which is characterized by a partially cystic proliferation that includes a double layer of columnar to cuboidal epithelial cells associated with lobules of lacrimal gland tissue, we identified evidence of apocrine secretion (i.e. apical snouts projecting into the lumen), either in the cystic component of the proliferation or in contiguous lacrimal duct, in all cases. One example was unusual. It manifested, in addition to typical cyst formation, with areas of ductal and probably acinar hyperplasia. We conclude that apocrine secretion in dacryops is a common and underrecognized phenomenon. Dacryops should be distinguished from apocrine hidrocystoma, a lesion commonly encountered in the periorbital area in the practice of dermatopathology.
