Abstract:
A small ruptured cyst was excised from the left inner canthus of a 68-year-old woman. Histopathology displayed a cyst lined by a double layer of cuboidal epithelium and filled with amorphous material. The lining cells were strongly positive for cytokeratins 5/6 and 14, with weak reactivity with cytokeratin 7. These findings were identical to those in a single previous report of an eccrine cyst of the eyelid, making this the second example of a bona fide eccrine hidrocystoma of the eyelid.
