ABSTRACT
Odontogenic tumors producing amyloid are rare neoplasms. Cholangiocarcinomas and fibromas are also referred to as infrequent. The objective of this study was to report the case of a dog, 17 years old, a poodle, who was treated at the Veterinary Hospital of the Federal University of Uberlândia. At necropsy, the animal presented only nodule located in the oral cavity, in the same way, only nodule in the hepatic parenchyma and in addition, multiple masses in the stomach. Microscopically, the histological features were compatible with odontogenic tumor producing amyloid, cholangiocarcinoma and fibroma, respectively. Reports of simultaneous occurrence of distinct tumors are scarce in the literature.
Os tumores odontogênicos produtores de amiloide são neoplasias raras. Os colangiocarcinomas e fibromas também são referidos como infrequentes. Objetivou-se relatar o caso de um cão, 17 anos, poodle, que foi atendido no Hospital Veterinário da Universidade Federal de Uberlândia. À necropsia, o animal apresentou único nódulo localizado na cavidade oral, da mesma forma, único nódulo no parênquima hepático e ademais, múltiplas massas no estômago. Microscopicamente, as características histológicas foram compatíveis com tumor odontogênico produtor de amiloide, colangiocarcinoma e fibroma, respectivamente. Relatos de ocorrência simultânea de tumores distintos são escassos na literatura.

The feline inductive odontogenic tumor (FIOT) is a rare entity among oral tumors in cats, the cytologic features of which are not well characterized but may prove useful. A fine-needle aspiration biopsy was performed on the right mandible between the permanent canine (404) and permanent fourth premolar (408) of an 8-month-old female mongrel cat. Cytologic smears showed epithelial cells and occasional spindle cells with extracellular homogenous acidophilic material in a hematic background. The initial diagnosis of benign tumor was confirmed by histopathologic examination of the biopsy specimen. This report describes the cytologic findings in a case of FIOT.
