Canine mast cell tumors, also known as mastocytomas, mast cell sarcomas or MCTs, are abnormal, cancerous (neoplastic) and unfortunately fairly common accumulations of mast cells that form nodular skin masses in dogs. About fifty percent of canine mast cell tumors are malignant. When MCTs metastasize, they typically go first to lymph nodes in the region of the primary mass. Thereafter, metastasis normally is to the spleen, liver, mesenteric lymph nodes, other cutaneous (skin) sites and
Mast cell tumors (MCTs) vary greatly in appearance and can occur in many different places on a dog’s body. Unfortunately, it is difficult if not impossible to determine whether a mast cell tumor is malignant or benign based upon appearance alone.A mast cell tumor usually shows up as an isolated lump or mass, although they can appear in clusters or in multiple areas of the skin. Most affected dogs show no symptoms of irritation or
Any lumps or bumps felt on or under a dog’s skin should be assessed by a veterinarian as soon as possible. Mast cell tumors (MCTs) are common in domestic dogs and are especially variable in appearance, size, location and growth pattern. They often are mistaken by owners as a minor insect bite or other unimportant skin reaction.Canine mast cell tumors can present in any number of ways. They can look like any other skin tumor,
Mast cell tumors (MCTs) can be benign. However, they have the potential to become malignant and often metastasize to sites other than the skin. Therefore, any skin lump should always be assessed by a veterinarian and, if found to be a mast cell tumor, treated immediately. The goals of treating mast cell tumors are to control the local disease or other conditions associated with the tumors, and most importantly to prevent metastasis if at all
