Plain-English summary
A 13-year-old spayed female dog was brought in for a swollen belly and a large mass that could be felt in her abdomen. An ultrasound showed a 30 × 20 cm mass attached to her spleen, and surgery confirmed it was a malignant tumor made up of different types of tissue. Fortunately, after the surgery, there were no signs of the tumor coming back or spreading during a nine-month follow-up. This case highlights the importance of checking for rare tumors like malignant mesenchymoma when a dog has a large mass in the spleen.

Abstract
A 13-year-old spayed bitch was referred for evaluation of an abdominal distension with a palpable, continuously growing mass. Abdominal ultrasonography revealed a 30 × 20 cm mass directly connected to the spleen. Surgical exploration confirmed the sonographic diagnosis with adhesions to the omentum and the liver. Pathohistological samples revealed well differentiated adipose tissue and variably differentiated collagenous and myxomatous tissue. Immunohistochemically, vimentin and in some regions alpha smooth muscle actin were expressed indicating smooth muscle differentiation. The results support the diagnosis of a malignant mesenchymoma composed of liposarcoma, mixosarcoma and leiomyosarcoma. No local recurrence or metastasis occurred during a nine month follow-up. So far, only two pathological retrospective studies describing the common prevalence and properties of canine splenic malignant mesenchymomas were found in the literature. However, this rare tumor entity has to be considered as a differential diagnosis in cases of large splenic masses.
