A 7-year-old castrated male Labrador retriever was referred for evaluation of progressive hind limb paresis of 4 weeks’ duration. On computed tomography and magnetic resonance imaging examination, masses were found in several regions including the lung, right kidney, and peritoneum. Additionally, an extradural mass at the region of T13–L1 was identified, which is assumed to related to the chief complaint, progressive hind limb paresis. With the consent of the owner, a dorsal laminectomy was performed to remove the mass and surrounding tissues for the palliation of the hind limb paresis. Hematoxylin and eosin staining and immunohistochemical examination revealed the mass to be consistent with an undifferentiated (high-grade) pleomorphic sarcoma. The patient presented with recurrence of the hind limb paresis, respiratory discomfort, and urinary incontinence. The owner declined treatment and the dog was euthanized. Systemic metastasis was confirmed on postmortem microscopic examination. To the authors’ knowledge, this is the first report describing multiple undifferentiated high-grade pleomorphic sarcoma with extradural involvement developing into the vertebral canal through the intervertebral space, resulting in spinal damage, in a dog.

Undifferentiated pleomorphic sarcoma constitutes less than 5 % of all sarcomas in adults and has been rarely seen in the breast and is dened as a group of pleomorphic, high-grade sarcomas in which any attempt to disclose their line of differentiation has failed . Most undifferentiated pleomorphic sarcomas(UPS) have occurred in their sixth and seventh decades of life and very rarely in adolescents and adults. We report a case of 24 year old female presented with painless lump in right breast and rapidly increasing in size for last 5 months. Iinitial diagnosis was made as sarcoma breast on the basis of physical and radiological examination. After that total mastectomy was done without axillary lymph node dissection, as lymphatic spread is very rare. But without histopathological examination and most importantly IHC-panel, it is impossible to make a denitive diagnosis of UPS breast.
