“…Um estudo comparativo de Ghirelli et al (2013), em 21 cães, sobre a eficácia da técnica radiográfica convencional versus tomografia computadorizada (TC), na avaliação da invasão de estruturas adjacentes aos tumores de localização oral, os autores observaram uma eficiência de 95.2% da TC contra 30% do exame radiológico convencional.…”

RESUMO.O objetivo deste relato foi descrever a ocorrência de um fibrossarcoma em uma cadela da raça Golden Retriever, com 12 anos de idade, pesando 42 kg. O animal apresentou histórico clínico de aumento do volume do plano nasal. Ao exame específico da cavidade oral, foi encontrada uma massa aderida à porção rostral do maxilar, encapsulada, medindo cerca de 5 cm de diâmetro, que se estendia cranialmente ao plano nasal, causando sua obstrução. Foi realizada biópsia incisional e o diagnóstico realizado com base na avaliação histopatológica. O animal foi submetido à quimioterapia neoadjuvante citorredutora e maxilectomia rostral bilateral. Até o momento não foi observada recidiva locorregional ou doença metastática. No Brasil, ainda são escassos os relatos de literatura envolvendo cirurgias radicais ou reconstrutivas em tumores oronasais. Palavras chave: cães, tumor, neoplasias da cavidade oralOral fibrosarcoma of low histological grade and high biological aggressiveness: case report ABSTRACT. The objective of this report was to describe the occurrence of a fibrosarcoma in a 12-year-old golden retriever, weighing 42 kg. The animal presented a clinical history of increased nasal plane volume. At the specific examination of the oral cavity, a mass adhered to the rostral portion of the maxilla was found, encapsulated, measuring about 5 cm in diameter, which extended cranially to the nasal plane, causing its obstruction. An incisional biopsy was performed and the diagnosis was made based on the histopathological evaluation. The animal was submitted to neoadjuvant chemoradiotherapy and bilateral rostral maxilectomy. To date no locoregional recurrence or metastatic disease has been observed. In Brazil, reports of literature involving radical or reconstructive surgeries in oronasal tumors are still scarce.

Case summaryA 10-year-old castrated male domestic shorthair cat was presented for assessment of a gingival mass surrounding the left maxillary third and fourth premolar teeth. The mass was surgically removed by means of a marginal rim excision, and the tissue was submitted for histological assessment. It was identified as a benign cementoblastoma (true cementoma). There was proliferation of mineralized eosinophilic material with multiple irregularly placed lacunae and reversal lines, reminiscent of cementum. The cat recovered uneventfully from the anesthesia, and there was no evidence of tumor recurrence 6 months after surgery.Relevance and novel informationCementoblastomas (true cementomas) in domestic animals are rare, with just a few reports in ruminants, monogastric herbivores and rodents. Cementoblastoma is considered a benign tumor that arises from the tooth root. The slow, expansive and constant growth that characterizes these masses may be accompanied by signs of oral discomfort and dysphagia. This case report is intended to increase knowledge regarding this tumor in cats and also highlights the importance of complete excision of the neoplasm. To our knowledge, there are no previous reports in the literature of cementoblastoma in the cat.

“…Imaging, particularly with CT and magnetic resonance imaging (MRI), can also be used when evaluating the local extent of disease to help determine if a tumor is resectable and to help plan the surgical dose needed to attempt a complete resection (5). CT in general is considered superior than standard radiography in identifying tumor, underlying boney change as well as invasion into adjacent structures (6) as noted in Figure 1 with a canine nasal carcinoma. MRI can also help delineate the extent of tumor and whether a complete resection is possible.…”

Imaging is critical for the diagnosis and staging of veterinary oncology patients. Although cytology or biopsy is generally required for diagnosis, imaging characteristics inform the likelihood of a cancer diagnosis, can result in a prioritized list of differentials that guide further staging tests, and assist in the planning of surgery, radiation, and chemotherapy options. Advanced imaging, such as CT and MRI, can better define the extent of disease for surgical and radiation planning for head and neck cancer cases in particular. Additionally, new imaging technologies are continually being translated into veterinary fields, and they may provide more options for cancer patients as they become more widely available.
