Acanthomatous ameloblastoma in canine (Canis lupus familiaris): case report

Abstract

The presence of neoplasms at the level of the oral cavity in dogs is evidenced by 9% in clinical studies, allowing a difference of 29% for benign cases and 32% for malignant cases. A 10-year-old female of the canine species, of the fox terrier breed, sterilized, living under the supervision of guardians. It was clinically evaluated by the presence of a proliferative mass with areas of hyperpigmentation at the level of the lower lip rostral to incisor and canine teeth at the level of the mandibular bone, with a compromise of the oral vestibule and sublingual caruncles. Histopathology indicated that the sample contains an abundant amount of dense, non-patterned fibroblastic tissue, with collagenous bundles in different directions, occasionally including well-differentiated bone tissue, which contains a medullary cavity. The morphopathological diagnosis consisted of an ossifying fibroma / acanthomatous ameloblastoma with ulcerative stomatitis. The case was approached from a surgical setting by means of a bilateral partial rostral mandibulectomy and the incorporation of an esophageal catheter, during the postoperative period. Through this report we seek to publicize presentations of this type of neoplasm and allow, through specific diagnoses, to make decisions that can support the quality of life of our patients.
