Abstract
A 6-year-old male Shih tzu dog was presented for evaluation of abdominal distention. Abdominal radiography and ultrasonography revealed a soft tissue density mass containing large amount of fluid. Ultrasonography-guided fine needle aspiration of the mass was performed and cytologic impression was granulation tissue with hematoma and fibroplasias. On exploratory laparotomy a mass was identified at the root of mesentery adhered to distal jejunum. Because the mass could not be separated from the attached jejuna loops, the mass and the adhered sites were surgically removed all together and enteroanastamosis was performed. Histologically a low grade myxosarcoma was diagnosed. Tumor cells were positive with alcian blue stain and Ki67 index by immunohistochemistry was 2.5. The dog recovered from surgery uneventfully, and has been in good condition without any signs of recurrence or metastasis for about 30 months after surgery.
