Histiocytomas in Dogs
Histiocytomas can affect dogs of any age or breed. Though they can appear on any location on the body, the vast majority of histiocytomas appear on the head. Histiocytomas usually occur on dogs under three years of age; they are one of the most common tumors in this age group.
These tumors appear rapidly and are small, round, and hairless. They will often ulcerate and then become smaller and go away. They usually appear as a solitary mass, but more than one may be present at a time. These tumors are benign and are not considered to be a health risk.
Treatment for Histiocytomas
Treatment often involves simply letting the tumor run its course. Histiocytomas can be surgically removed, if they are bothering the dog and are in a location where removal will allow for closure of the skin. They can also be treated with topical steroids and antibiotics if they ulcerate or become inflamed or infected. However, most dogs never receive nor require any treatment intervention. If a dog owner sees a small tumor that develops on his or her dog, he or she should make sure to have it examined by a veterinarian.
