Plain-English summary
A 13-year-old Pomeranian was brought in with a swollen belly and not wanting to eat for two months. Tests showed a large tumor in her abdomen, which was removed through surgery. Unfortunately, the tumor was identified as a myxosarcoma, a type of cancer, and despite starting chemotherapy afterward, the tumor came back about seven weeks later. The dog remained stable for a while but sadly passed away about three months after the surgery.

Abstract
A 13-year-old intact Pomeranian bitch presented with a 2-month history of abdominal distension and anorexia. Ultrasonography and computed tomography revealed a large tumor in the abdominal cavity without metastases. The tumor was surgically resected and histopathologically characterized by spindle-shaped to atypical-shaped neoplastic cells with basophilic stroma in the omental adipose tissue. Immunohistochemistry revealed that the neoplastic cells were positive for vimentin but negative for cytokeratin, S-100 protein, and α-SMA. The bitch was diagnosed as a myxosarcoma arising from the greater omentum. Postoperatively, metronomic chemotherapy with cyclophosphamide and piroxicam was initiated. The tumor recurred on postoperative day 49. Although the bitch died 102 days after the initial examination, her general condition was maintained until death.
