Plain-English summary
A group of 23 dogs with low-grade mast cell tumors (MCTs) underwent surgery to remove the tumors, which ranged from 0.3 to 2.6 cm in size. The surgical technique involved removing the tumors with margins that matched the size of the tumors. After follow-up periods of up to over two years, none of the dogs experienced a return of the tumors at the surgery site. This suggests that removing small, low-grade MCTs with appropriate margins is an effective treatment option for dogs.

Abstract
We evaluated the postsurgical outcomes of cutaneous or subcutaneous mast cell tumors (MCTs, n=25) in 23 dogs, resected with lateral surgical margins proportional to the widest tumor diameter, including at least one facial plane. The tumor diameter range was 0.3-2.6 cm (median: 0.9 cm), and all were histologically diagnosed as Kiupel's low-grade MCT. Resection was histologically complete in 20, close (deep margin) in three, and incomplete (deep margin) in two. No dogs developed local recurrence at the site of initial surgery during follow-up of 161-2,219 days (median: 976 days). These results suggest that resection of low-grade, relatively small MCTs with surgical margins proportional to the tumor diameter is a practical procedure with high success rates.
