Multiple digital tumours in a rottweiler

An eight-and-a-half-year-old rottweiler bitch was examined on four separate occasions over a period of 32 months for lameness caused by a mass on a digit. On each occasion the mass and affected digit were amputated. Three different neoplasms were diagnosed: two squamous cell carcinomas, a melanocytoma and an intracutaneous cornifying epithelioma. There was no recurrence following surgical excision.
