The eyelid contains the ducts of numerous structures, including the lacrimal gland and the apocrine and eccrine sweat glands. Cysts may develop in any of these ducts. A cyst arising from the duct of the lacrimal gland is called dacryops. Cysts arising from sweat ducts are referred to as either apocrine or eccrine hidrocystomas (Fig 13-11). Histologically, ductal cysts typically are lined with a double layer of cuboidal epithelium, as are the ducts from which they arise. The lumen of the cyst typically appears empty.
