A histiocytoma is a benign button-like skin growth often occurring in younger dogs, especially Golden Retrievers, Boxers, and Dachshunds. This itchy, moist, sometimes bloody growth can be difficult to distinguish from some cancerous tumors so lab testing will be recommended. Though benign histocytomas are often irritating to the pet and thus it's recommended to remove it surgically.
Elbow hygromas are fluid-filled swellings that occur on the point of the elbow, often in short-haired, large breed dogs. Caused by the chronic trauma of lying on the elbows on a hard surface, they can be irritating and unpleasant. A change the patient's bedding is recommended, and depending on the case surgical drainage may be needed.
Sebaceous gland tumors present as small, round, cauliflower-shaped masses that may crust or bleed. Often confused for warts which tend to resolve themselves, sebaceous gland tumors will not go away on their own. While most of these tumors are benign, removal and lab testing may be indicated.
Lipomas, cysts, and warts, are all common benign skin growths. Lipomas are fatty tumors that can get quite large and irritating for pets. Cysts are fluid-filled sac of cells, often the result of blocked ducts or glands. Warts are benign growths caused by canine papilloma virus. Any or all of these growths may be removed if large, ulcerated, or irritating to the patient, or if the owner wants them removed for cosmetic reasons.
