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 λ light chain. CD20, CD3, κ 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.
