A mastocytoma in dogs (or mast cell tumor in dogs) is a neoplasm originating from mast cells in the domestic dog, which occurs mainly in the skin and subcutis. Mastocytoma are not only extremely common in dogs, but also tend to be much more malignant in them than in other animal species.
Disseminated mastocytosis is rarely seen in young dogs and cats, while mast cell tumors are usually skin tumors in older dogs and cats. Although not always malignant, they do have the potential to be. Up to 25 percent of skin tumors in dogs are mast cell tumors, [1] with a similar number in cats. [2]
Many types of skin tumors, both benign (noncancerous) and malignant (cancerous), exist in cats and dogs. Approximately 20–40% of primary skin tumors are malignant in dogs and 50–65% are malignant in cats. Not all forms of skin cancer in cats and dogs are caused by sun exposure, but it can happen occasionally. On dogs, the nose and pads of ...
The most likely candidates include interdigitating DC in lymphoid tissues and perivascular interstitial DC in other involved tissues. Immunophenotyping and careful morphological assessment should also avoid confusion of HS and MH with the large cell form of cutaneous T cell lymphoma, and poorly differentiated mast cell tumors.

Dogs can develop many of the same types of cancer as humans. Many canine cancers are described with the same terminology and use the same classification systems as human cancers. [1] Mast cell tumors are the most common type of skin cancer in canines. [1] Lymphoma; Prostate cancer; Brain cancer; Hemangiosarcoma is a type of cancer that is ...
Mammary (breast) cancer on a dog. Mast cell tumor on dog. Veterinary pathologists are veterinarians who specialize in the diagnosis of diseases through the examination of animal tissue and body fluids. [1] Like medical pathology, veterinary pathology is divided into two branches, anatomical pathology and clinical pathology. Other than the ...
Toceranib (INN [2]), sold under the brand name Palladia, is a receptor tyrosine kinase inhibitor that is used in the treatment of canine mast cell tumor also called mastocytoma. [3] It is the first medication developed specifically for the treatment of cancer in dogs. [4] [5] It is used as its phosphate salt, toceranib phosphate.
Hemangiosarcoma of the skin in a dog. Hemangiosarcoma is quite common in dogs, and more so in certain breeds including German Shepherds and Golden Retrievers. [3] It also occurs in cats, but much more rarely. Dogs with hemangiosarcoma rarely show clinical signs until the tumor has become very large and has metastasized.
