Lingual extramedullary plasmacytoma in a 9‐year‐old American Pitbull terrier

Abstract

AbstractA 9‐year‐old, female, spayed American Pitbull terrier presented for a month‐long history of lethargy, inappetence, altered breathing and unusual tongue movement. Severe anaemia was noted on bloodwork. Oral exam revealed an exophytic, pale, tan mass at the tongue base. A computed tomography scan was performed, followed by surgical removal of the mass. Histopathology confirmed the mass as an extramedullary plasmacytoma. Within 24 hours of removal, the clinical signs and anaemia were improving, and the dog was released from hospital. On follow‐up 2 weeks postoperatively, the dog's bloodwork was all within normal parameters, the anaemia was completely resolved, and the dog was doing well at home. After 692 days of successful removal of the tumour, the owner reports the dog is doing well at home.
