Most commonly histiocytomas are found in young dogs and appear as a small, solitary, hairless lump, [6] although Shar Peis may be predisposed to multiple histiocytomas. [7] They are most commonly found on the head, neck, ears, and limbs, and are usually less than 2.5 cm in diameter. [8] Ulceration of the mass is common.
In the domestic horse, they occur primarily in older animals in the head and neck region and lower limb sections. The recurrence rate is low with proper surgical removal. [49] In the domestic cat, mastocytomas of the skin are mostly benign. Histologic grading, as in the dog, has not been shown to be useful.
Overweight female dogs are especially prone to developing these tumors, and most older or overweight dogs have at least one lipoma. [46] [47] In dogs, lipomas usually occur in the trunk or upper limbs. [45] They are also found less commonly in cattle and horses, and rarely in cats and pigs.
It is a common result of head trauma in dogs. Most commonly it occurs in brachycephalic (short nosed) breeds. [63] Horner's syndrome* results from damage to the sympathetic innervation of the eye. Signs include enophthalmos (sunken eye), miosis (small pupil), elevated third eyelid, and ptosis (drooping of the upper eyelid).
Mast cell tumors are known among veterinary oncologists as 'the great pretenders' because their appearance can be varied, from a wart-like nodule to a soft subcutaneous lump (similar on palpation to a benign lipoma) to an ulcerated skin mass. Most mast cell tumors are small, raised lumps on the skin. They may be hairless, ulcerated, or itchy.

Contagious infections include parasitic, bacterial, fungal and viral skin diseases. One of the most common contagious parasitic skin diseases is Sarcoptic mange (scabies).
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.
