Occasionally, depending on location, amputation may be required to remove the entire tumor. However, there are many things that look like warts and a definitive diagnosis may require identification of the virus or its effects on individual cells (a change known as koilocytic atypia or koilocytosis). If the entire tumor cannot be removed, reducing the size of the tumor can help improve signs. Amputation neuromas are disorganized growths that form after amputation or traumatic injury. Shetland Sheepdogs and Beagles are most at risk for liposarcomas.

Some form pimples or dark, thick skin folds. A dermatofibroma can occur anywhere on the skin. After surgical removal, tumors should be evaluated under a microscope (called a histopathology test) to confirm the type of tumor and whether all of the tumor was likely removed. They also get some solar radiation that reflects from the ground. These tumors do not spread to other organs; however, extension to surrounding tissues is common. Fibromas occur in all breeds but are primarily a tumor of aged dogs. They are rare in all domestic animals but occur most often in older dogs and cats.

These include amputation neuromas, neurofibromas, and neurofibrosarcomas. For dogs, surgical removal, such as the amputation of the involved toe or ear, is the proper treatment. Biopsy evaluation (laboratory study of a tissue sample taken from the tumor) is the best means of diagnosis. If malignancy is suspected, tissue surrounding the tumor will also be removed to increase the chance that none of the tumor cells are left behind. Surgery is the usual treatment.
