| LIPOMA, LIPOSARCOMA, LIPOMATOSIS, INFILTRATIVE LIPOMA IN DOGS AND CATS | |
| Description | Lipomas are common (dog) or rare (cat) benign neoplasms of older animals. They are single or multiple and common sites are the thorax, brisket, internal or external abdomen, and proximal limbs. These tumors can cause mechanical interference or pain due to location. Poorly-circumscribed infiltrative Lipomas have been described. Lipomas with a fibrous content are fibrolipomas. Liposarcomas are rare neoplasms in either the dog or cat and are infiltrative but rarely metastasize. Intrathoracic Lipomas might cause respiratory signs. |
