Callie, a twelve year old female spayed West Highland White Terrier, presented to the Cornell University Hospital for Animals Oncology Service on 11/14/07 for evaluation of a nasal mass. During the previous year, the owners noticed that Callie was sneezing more frequently than usual. The rDVM administered antibiotics on two separate occasions which temporarily helped but the symptoms returned. Callie then began having mild epistaxis, with short periods of mild mucohemorrhagic nasal discharge. In June of 2007, rDVM radiographs revealed a large nasal mass. Repeat radiographs in 2-3 months revealed significant growth. The rDVM submitted a cytological sample which revealed supperative inflammation and negative fungal culture, however no diffinitive diagnosis was made at that time. Callie had begun snoring, but could otherwise breathe through her nose. The owners noted that she had many skin masses over her entire body, but was an otherwise healthy dog.
