Sažetak
A 7-year old mix-breed dog was admitted to the Clinic due to neoplasia in region of left mandibular canine tooth. The neoplasia was polyp like been size. The dog underwent physical examination, which was unremarkable. Complete blood count showed only leukopenia. Serum biochemistry results were in normal range. Fine needle aspiration of neoplasia did not reveal diagnose due to small cell count. Dog underwent excision of neoplasia in a general inhalation anesthesia. Histopathology revealed neoplastic proliferation that is extending from hyperplastic mucosa and expanding the subepithelial connective tissue. Neoplasia is composed of irregular cords of columnar to polygonal epithelial cells with moderate amount of eosinophilic cytoplasm, while peripheral cells contained antibasilar nuclei. Nuclei were vesicular, with 1-2 nucleoli. Anisokaryosis was moderate and mitotic rate was 10/10 HPF. Multifocally there were islands of osteoid and bone tissue with bone lysis and ossification. Occasionally within the stoma there were mixed inflammatory infiltrates, diffuse edema and focal hemorrhage. Histologic findings favored the diagnosis of acanthomatous ameloblastoma which is known as a locally aggressive jaw tumor with high propencity for recurrence. Ameloblastomas are benign odontogenic neoplasms that rarely become malignant and can occur in the maxilla or mandible. Tumor relapsed 3 months after initial excision. The X-ray findings in neoplasia region showed mild periosteal reaction from the third incisor to the second premolar with canine root degeneration of the left mandibula. The treatment of choice was the partial mandibulectomy in a general inhalation anesthesia. Recovery was in a short period without any complications of healing process. In our case report, despite accurate tumor margins assessment following the first neoplasia excision, acanthomatous ameloblastoma confirmed his aggressive proliferation in short period resulting in odontogenic degeneration.
