Abstract

It’s rare for a dog to have different types of tumors growing at the same time. Mastocytoma (MCT) is a tumor composed of mast cells that most often form nodules or lumps on the skin, often single, and prone to rapid growth with an ulcerated surface. Canine liposarcoma is an uncommon soft tissue sarcoma, it grows slowly and varies in size, usually arising in the subcutis. A 10-year-old male Labrador retriever was presented with an increasing subcutaneous swelling lasting for 3 years. Fineneedle aspirates revealed that one of the five tumors was a mastocytoma and four were liposarcoma. A complete blood count and biochemical abnormalities were mainly globulin, gran, Lymph%, and Mon%, all other parameters were within reference limits. The owner decided to undergo surgery, which removed the tumor and sent it to the authorities for testing, histopathological findings and the results were consistent with the previous cytological results. After six months of follow-up, there was no sign of recurrence. To the authors’ knowledge, this is the first report describing a case of mastocytoma and liposarcoma in a dog
