Maxillary central giant cell granuloma in a dog

A young labrador dog had a rapidly enlarging osteolytic lesion of the left maxillary bone. The histological diagnosis was central giant cell granuloma. This is a benign, non‐neoplastic lesion that has some radiographic and histological similarities to malignant bone tumours of this region. The importance of biopsy in making the diagnosis is emphasised because surgical treatment of central giant cell granuloma by resection or curettage usually resolves these lesions.
