Plain-English summary
A 14-year-old male horse, used for hunting, had a sore growth on the left side of his mouth. A biopsy showed that this growth was a type of cancer called poorly differentiated carcinoma. The horse had surgery to remove the mass, but it grew back a few months later, so he received radiation treatment. Although there was some initial improvement, his condition worsened significantly, and he was humanely put to sleep. A thorough examination after his passing showed that he had a very enlarged right kidney and cancer that had spread throughout his body.
Abstract
A 14-year-old hunter gelding presented with an ulcerated mass on the left premaxilla. Biopsy of the mass revealed a poorly differentiated carcinoma. Surgical excision was attempted, but local regrowth followed several months later, at which point radiotherapy was carried out. An initial improvement was followed by marked deterioration and the animal was humanely killed. Post-mortem examination revealed a massively enlarged right kidney and associated widespread metastases. A metastatic clear cell renal carcinoma was identified by histological examination.
