Radiation therapy for the treatment of canine progressive cutaneous angiomatosis: Description of 2 cases

Two dogs with histologically confirmed progressive cutaneous angiomatosis were presented because of extensive and progressive cutaneous lesions of 1 hind limb causing pain and lameness. Radiation therapy was offered to treat disease recurrence after amputation in the first case and as first treatment in the second case. Metronomic therapy was added in both dogs. Complete and partial regression of the cutaneous lesions was achieved, respectively, with a period of 31 months of disease-free interval (first case) and 12 months of stable disease (second case). Self-limiting grades I and II acute side effects were observed. Radiation therapy can be an alternative to surgery in the treatment of inoperable cutaneous progressive angiomatosis.
