Plain-English summary
An 11-year-old male Bearded Collie was brought in with a large skin mass on his right thigh, which turned out to be a rare type of cancer called malignant trichoepithelioma. After surgery to remove the mass, the dog developed back pain due to the cancer spreading to his spine. Radiation therapy was given to help relieve the pain, and it also reduced the size of new skin tumors that appeared later. Although the treatment helped manage his symptoms, the cancer ultimately spread, and the dog passed away 17 months after the initial surgery.

Abstract
An 11-year-old male Bearded Collie was brought to the Gifu University Animal Medical Centre with a skin mass on the lateral right thigh. Physical examination revealed a 30 × 65-mm oval mass with an alopecic and ulcerated surface. Histopathology of the surgically excised sample confirmed malignant trichoepithelioma. Five months after the surgery, the dog experienced lumbar pain resulting from metastasis to the lumbar vertebrae. Radiation therapy (RT) was performed and it alleviated the lumbar pain. Nine months after the surgery, multiple skin metastases were identified. RT was performed at each occurrence, which reduced the size of each tumour and resulted in a partial response; however, systemic metastasis occurred and the dog died 17 months after the initial surgery. Canine malignant trichoepithelioma is a rare tumour, so an effective treatment has not been determined. Data from our case study indicate that RT has potential for pain control of primary and metastatic malignant trichoepithelioma.
