Plain-English summary
A 7-year-old American Cocker Spaniel was brought in with swelling of the third eyelid gland, along with discharge and some redness in the eye. After examining the mass, the veterinarian performed surgery to remove it and found that it was a type of tumor made up of abnormal plasma cells. Fortunately, a year after the surgery, the dog showed no signs of the tumor returning. This case is notable as it is the first reported instance of this specific type of tumor in a dog's third eyelid gland.

Abstract
A case of extramedullary plasmacytoma of the third eyelid gland in a 7-year-old American Cocker Spaniel is reported. An enlargement of the third eyelid gland, abundant mucopurulent discharge, mild hyperemia and corneal pigmentation in the OD was present. Excisional biopsy of the mass revealed the gland was infiltrated and partially destroyed by a uniform population of neoplastic plasma cells. The neoplastic cells were positive for CD138, Ki-67 and lambda light chain. CD20, CD3, kappa light chain and cytokeratin were negative. Twelve months following surgery, no recurrence was observed. To the authors' knowledge, this is the first extramedullary plasmacytoma of the third eyelid gland reported in dogs.
