Apocrine Cystadenoma (Hydrocystoma)
Description of the Disease and Clinical Picture
Apocrine cystadenoma, also known as hydrocystoma, is a benign cystic tumor that arises from the apocrine (sweat) glands of the eyelids. One or more painless changes are observed on the eyelids, ranging in size from 1 to 10 mm, gray in color, and of cystic structure. The cysts contain dark brown fluid. Generally, they are not problematic unless the tumor is located at the very edge of the eyelid and grows large enough to irritate the cornea. Occasionally, the cyst may rupture, allowing the contents to reach the surface of the eye and cause additional irritation. This condition is most commonly seen in Persian and Himalayan cats. In dogs, this tumor is extremely rare.
 
Therapy
There are several methods for removing apocrine cystadenoma. Surgical excision of the mass, drainage through aspiration, cryotherapy, laser removal, or chemical ablation are options. Because these tumors frequently recur, if the cat does not exhibit any discomfort, the owner is advised not to remove the cysts but to monitor them regularly.
