Abstract
An 18-year-old male Yorkshire Terrier was admitted with a history of neurological signs
including dullness and progressive tetraparesis. Physical examination revealed bilaterally
symmetrical alopecia and pot-bellied abdomen. Computed tomography and necropsy examination
showed a mass across the frontal sinus and cerebral frontal lobe, bilateral adrenocortical
hyperplasia, and hepatomegaly. Histopathologically, the tumor lesions consisted of sheets,
nests, or cords of small- to medium-sized round-to-polyhedral cells. Adrenal cortex showed
bilateral diffuse cellular proliferation, and some hepatocytes showed intracytoplasmic
glycogen accumulation. Immunohistochemically, the tumor cells were positive for
pancytokeratin, chromogranin-A, neuron-specific enolase, S100, synaptophysin, and thyroid
transcription factor-1 but negative for microtubule-associated proein-2 and neurofilament,
leading to the diagnosis of neuroendocrine tumor. These tumor cells were also positive for
adrenocorticotropic hormone.

TERATOMA OF THE OVARY IN A FREE-RANGING JAPANESE RACCOON DOG (NYCTEREUTES PROCYONOIDES VIVERRINUS). J Zoo Wildl Med 2017; 48:265-268.

Abstract
A young adult, female, free-ranging Japanese raccoon dog ( Nyctereutes procyonoides viverrinus) with scabies infection was found dead as a result of traumatic injuries presumed to reflect vehicular trauma. Necropsy showed a large solid mass located on the left ovarian region, occupying a third of the abdominal cavity. Histologically, the mass contained complex tissues derived from three germinal layers, with areas of cuboidal or columnar epithelium, keratinized squamous epithelium, bone, cartilage, and adipose tissue. This paper presents the first morphologic description of ovarian teratoma in a raccoon dog.

Abstract
A 17-year-old female wolf (Canis lupus lupus) had a right lung mass that was adhered to the thoracic cavity. Histopathological examination revealed that the mass consisted of sheets, cord or ribbon-like structures of monotonous, small, cuboidal cells with round, oval or short-spindle nuclei and scant clear cytoplasm, demarcated by a fine fibrovascular stroma. Focal necrosis, congestion and thrombi were observed. Immunohistochemically, the tumor cells diffusely expressed cytokeratin AE1/AE3, and some expressed chromogranin A, neural cell adhesion molecule (CD56) and thyroid transcription factor-1. The number of proliferating cell nuclear antigen-positive tumor cells was low. A diagnosis of pulmonary neuroendocrine tumor was based on the resemblance to carcinoids.

FOLLICULAR CELL CARCINOMA OF THE THYROID GLAND IN THREE CAPTIVE AGED RACCOON DOGS (NYCTEREUTES PROCYONOIDES). J Zoo Wildl Med 2015; 46:889-94.

Abstract
The clinical and histologic features of thyroid carcinoma in raccoon dogs have not been previously reported. Three of four raccoon dogs (Nyctereutes procyonoides) over 8 yr of age at the Nogeyama Zoological Gardens developed thyroid follicular cell carcinomas that were detected at necropsy. The affected raccoon dogs were rescued from the wild and were housed at the Nogeyama Zoological Gardens for 8 yr 8 mo, 8 yr 10 mo, and 10 yr 3 mo, respectively. Although all of them appeared lethargic and developed partial alopecia or desquamation of their skin, they did not display any other specific clinical signs associated with a thyroid lesion. Serum thyroid hormone values were examined in two of the affected raccoon dogs and the average and standard deviation values (free-thyroxin [FT4]: 0.078 ± 0.077 pM/L and 0.062 ± 0.0039 pM/L; free-triiodothyronine [FT3]: 3.261 ± 0.765 pM/L and 3.407 ± 0.919 pM/L) were lower than the reference range (FT4: 0.141 ± 0.117 pM/L; FT3: 5.139 ± 2.412 pM/L) derived from a clinically normal raccoon dog. On necropsy, the thyroid lobes were markedly enlarged bilaterally. Histopathologically, the neoplastic cells in the thyroid gland appeared round or oval and columnar or cuboidal with minimal heteromorphism. Moreover, mostly small (but occasionally large) follicles were identified, and the neoplastic cells had infiltrated into the surrounding capsule and blood vessels. The histopathologic features of the thyroid tumors in the raccoon dogs revealed that the tumors were derived from follicular cells.

Abstract
An intact, 8-year-old, male Golden Retriever dog was presented for evaluation of a nasal mass and approximately 30 firm, raised, variably ulcerated dermal and subcutaneous masses. Histopathology of both nasal and multiple skin masses revealed multiple nonencapsulated, infiltrative masses comprising clusters, anastomosing trabeculae, and packets of neoplastic, round to ovoid, hyperchromatic cells with marked nuclear molding. Surrounding the neoplastic cells was a marked stromal response in which many of the spindle-shaped cells expressed muscle-specific actin and had ultrastructural features consistent with myofibroblasts. A literature search indicates that this is the first report in a peer-reviewed journal of cutaneous metastasis of a nasal neuroendocrine tumor in any domestic animal species.
