Plain-English summary
A 4-year-old thoroughbred cross mare was brought in for a soft tissue tumor on her gums near her cheek teeth. After surgery to remove the tumor, it was found to be a fibrosarcoma, which is a type of cancer. The mare received additional treatment with chemotherapy injections directly into the tumor site. Although the tumor came back initially, after several treatments over 14 weeks, it stopped growing, and the mare showed no signs of the tumor for nearly five years afterward.

Abstract
A 4-year-old thoroughbred cross mare was referred to the University of Edinburgh Veterinary School Equine Hospital for treatment of a soft tissue tumor on the buccal gingival margin of the rostral right maxillary cheek teeth. The lesion was initially surgically excised and diagnosed as a fibrosarcoma via histopathology. Adjunctive treatment with intralesional cisplatin chemotherapy was begun. The tumor recurred and was repeatedly treated with intralesional cisplatin injections and additional surgical resection over the course of 14 weeks. Despite the initial poor response to treatment, no further regrowth of the tumor occurred 3 months following its final treatment. The horse remained free of visible evidence of tumor nearly 5 years later.
