Plain-English summary
A 12.5-year-old dog was brought in due to severe gum disease and swelling in the upper jaw. X-rays revealed issues with the teeth and bone in that area. The veterinarian performed surgery to remove several teeth and took tissue samples for further examination. The results showed a rare growth called a periodontal ligament hamartoma, which is a benign tumor related to the tissue around the teeth. Three months after surgery, the healing was going well, but the swelling in the jaw did not go away.

Abstract
A 12.5-year-old dog was presented for severe periodontal disease and bilateral maxillary enlargement. Radiographs of the maxilla showedgeneralized root resorption, ankylosis, and rarefaction of bone with focal radiodense areas. Surgical tooth extraction of multiple maxillary teeth and bilateral incisional biopsies of the periodontal tissue and maxilla in the region of the maxillary fourth premolars were performed. Histopathologic examination showed features typical of fully differentiated periodontal ligament with abundant cementum/alveolar lining bone and sparce odontogenic epithelial cell rests. Histopathology in conjunction with radiographic and clinical signs suggested a diagnosis of bilateral periodontal ligament hamartoma. Examination 3-months postoperatively indicated uncomplicated healing of the extraction and biopsy sites with no resolution of the maxillary enlargement.
