ABSTRACT
Apocrine hidrocystoma (AH) is a benign cystic lesion infrequently reported in the eyelids of cats. There are several reports of application of trichloroacetic acid (TCA) for treatment of eyelid apocrine hidrocystomas with high success rates in humans. This is the first report of intralesional injection of TCA for the treatment of eyelid AH in a feline. A 12-year-old Persian female spayed cat has been presented for evaluation of cystic masses on the eyelids. The cat had signs of ocular discomfort and two large cysts on the lower eyelid of the right eye. Ophthalmic examination was suggestive of eyelid AH. The cat underwent general anesthesia, and TCA 20 % was injected intracystically. The diagnosis of AH was confirmed by cytology. Two years later, there was no recurrence of the cyst. This case highlights the successful treatment of a large AH in the eyelids of a cat with TCA. Findings suggest that chemical ablation with TCA may be a useful treatment for AH in cats.
