A lipoma is a benign tumor made of fat tissue. [1] They are generally soft to the touch, movable, and painless. [1] They usually occur just under the skin, but occasionally may be deeper. [1] Most are less than 5 cm (2.0 in) in size. [2] Common locations include upper back, shoulders, and abdomen. [4] It is possible to have several lipomas. [3]
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.
Diagnosis and treatment are similar to that of the dog. Cases involving difficult to remove or multiple tumors have responded well to strontium-90 radiotherapy as an alternative to surgery. [28] The prognosis for solitary skin tumors is good, but guarded for tumors in other organs. Histological grading of tumors has little bearing on prognosis ...
The symptoms depend on the tumor's location and degree of invasion. For example, tumors in the gastrointestinal tract may cause vomiting, diarrhea, or weight loss. Tumors in the mouth may cause bad breath, difficulty swallowing, or lack of appetite. Tumors arising in the peripheral nerves may cause pain, lameness, or neurological symptoms.
These tumors can develop on the skin, subcutaneously, or on a blood vessel within an organ and are highly malignant. The tumors are most fatal when they rupture, causing the dog to suffer from severe loss of blood, or hypovolemia. [6] Dogs are one of three mammalian species that are known to suffer from a transmissible cancer. [7]
Immune therapy based on cultivation of tumor tissue is being developed for dogs. [22] A preventive vaccine based on several proteins commonly found in dog cancers, including hemangiosarcomas, is also being developed. [23] In the skin, it can be cured in most cases with complete surgical removal as long as there is not visceral involvement. [4]

Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
