Plain-English summary
A 12-year-old British Warmblood mare had a skin growth on her back that needed to be checked out. After testing the mass, the vet found it was a giant cell tumor, which is a rare type of skin tumor. The mare underwent laser surgery to remove the tumor, followed by a special light therapy to help with healing. Eight months later, there were no signs of the tumor coming back, indicating a successful treatment.

Abstract
A 12-year-old British Warmblood mare was examined by the referring veterinarian for evaluation of a cutaneous lesion on the dorsal thorax to the right of the midline. Cytologic examination of fine-needle aspirates from the mass was supportive of a giant cell tumor of soft parts (GCTSP). Laser surgical excision and postoperative methyl aminolevulinate (MAL) photodynamic therapy (PDT) were performed. Histologic examination of the mass confirmed the cytologic diagnosis. At 8 months from surgery, no evidence of recurrence has been observed. Giant cell tumors of soft parts are rare cutaneous neoplasms, observed in several domestic species, including the horse where they commonly appear as superficial cutaneous lesions without aggressive biologic behavior. Previously classified as giant cell variant of malignant fibrous histiocytoma, these superficial tumors have now been designated as giant cell tumors of soft tissue or giant cell tumors of low malignant potential within the category of fibrohistiocytic neoplasms.
