Plain-English summary
A 5-year-old Draft Horse gelding was brought in for a large, fleshy, ulcerated mass on his third eyelid that had been present for three weeks. After thorough examinations, including ultrasounds and X-rays, the mass was found to be a lacrimal gland adenocarcinoma, a type of cancer. The horse underwent surgery to remove the mass, and thankfully, there has been no recurrence or spread of the cancer one year after the procedure. This case is notable as it is the first reported instance of this type of tumor in a horse, and the surgery was successful in treating it.

Abstract
A 5-year-old Draft Horse gelding presented for evaluation of a large, fleshy, ulcerated third eyelid mass OD of 3 weeks duration. Complete ophthalmic examination, ocular ultrasound and skull radiographs revealed a large soft-tissue mass involving the entire third eyelid OD and extending into the ventral right orbit to the level of the globe equator. No other abnormalities were noted on physical or ophthalmic examination. Surgical removal via exenteration was performed 3 months after initial presentation. A lacrimal adenocarcinoma of the third eyelid was diagnosed based on histopathology. Concurrent asymptomatic intra-ductal and intra-acinar Demodex caballi parasites were found in the eyelid sebaceous glands, likely as an incidental finding. No tumor recurrence or metastasis has occurred 12 months after excision. To the author's knowledge, this case is the first reported primary lacrimal adenocarcinoma in a horse. Complete surgical excision was curative.
