Of 21 vascular tumors in equine skin, 18 were histologically benign (hemangiomas) and 3 were malignant (hemangiosarcomas). Of the 18 hemangiomas, 12 were in horses less than or equal to 1 year old, and 6 of these horses were born with the lesions. The 3 horses with hemangiosarcomas ranged from 8.5 to 13 years of age.
