Plain-English summary

A 13-month-old Standardbred colt had a recurring growth called a hemangioma, located at the base of his hoof. Previous surgeries to remove it had left a wound that wouldn't heal properly. To treat this, he received radiation therapy, which involved six sessions over three weeks, delivering a total of 36 Gy. After about four months, the wound healed well, and the colt was able to start training for racing six months after finishing the treatment. Now, 20 months later, he is healthy and there are no signs of the tumor coming back.

Abstract

A 13-month-old Standardbred Colt had a recurrent hemangioma at the level of the coronary band. Multiple excisions had led to a nonhealing skin and hoof defect. Using 14 MV electrons, a total dose of 36 Gy was administered, given as six fractions of 6 Gy twice a week. Wound healing by second intention was achieved over the next 4 months and the colt began race training 6 months after the end of therapy. Twenty months later the colt is sound and there is no evidence of tumor recurrence.
