Mielopatia compressiva por lipoma de células fusiformes infiltrativo em cão

Abstract

A female dog was referred presenting neurological signs of proprioceptive ataxy, proprioceptive deficit in the right pelvic limb, mild ambulatory paresis and spinal pain during the palpation in thoracic vertebrae. It was observed a right extradural compression of spinal cord over fourth and fifth thoracic vertebrae by spinal myelography. During necropsy evaluation, it was observed a neoplasm which infiltrated in the spinal canal in the fourth and fifth thoracic vertebrae with marked compression of the spinal cord. Microscopically there were well differentiated neoplasic adipocytes, with areas of spindle cells, diagnosed as infiltrative spindle cell lipoma. The immunohistochemical staining revealed positive CD34 cells mainly in the areas of spindle cells lipoma.
