|The patient was a seven year-old female terrier mixed breed dog. She was presented with the history of a mass growing on the right hindleg for 3 months which did not reduce the general health and the exercise tolerance.
The mass was pear shaped, hyperpigmented and 18 x 7 cm in width, beginning 2 cm from the vulva. It was not painful but showed fluctuation when palpated.
General examination was normal. The mass was completely resected and the dog was treated with cephalexin after surgery.
Gross pathology showed only myxomatous tissue and other anatomical structures were not detected. Histopathology showed that the tumour was composed of connective tissue that formed mucin. The nuclei appeared round to stellate, the intercellular spiral and slender fibrils were white-bluish and showed little parallelism.
