Abstract

Relata-se um caso de lipoma de células fusiformes infiltrativo diagnosticado em cadela com sinais neurológicos de ataxia proprioceptiva, reação postural ausente no membro pélvico direito, paraparesia fracamente ambulatória e dor à palpação sobre as vértebras torácicas craniais. A mielografia demonstrou compressão extradural do lado direito sobre a quinta vértebra torácica. À necropsia foi observado neoplasma que invadia o canal vertebral na quarta e quinta vértebras torácicas com compressão acentuada da medula espinhal. Microscopicamente, foram observados adipócitos neoplásicos bem diferenciados, com áreas de células fusiformes, diagnosticado como lipoma de células fusiformes infiltrativo. A avaliação por imuno-histoquímica, com anticorpo anti-CD34, revelou positividade principalmente nas áreas fusiformes do lipoma.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.
