Abstract
Over the last 20 years, substantial knowledge has been developed in Veterinary oncology, and tumors previously reported only in humans have been identified in animals. Primary paragangliomas of the tongue are extremely rare tumors in human beings and have never been reported in animals. A Chow Chow dog showed an ulcerated nodule at the lingual body, deeply infiltrated, which extended to the base of the tongue. A full clinical and pathological investigation was conducted, and a post-surgical follow-up of 6 months did not detect recurrence. Cytological, histological, and immunohistochemical features are presented and support the diagnosis of lingual paraganglioma. The paraganglioma of the tongue reported in this Chow Chow dog shares many similarities with the human counterpart.

Abstract
An 11-year-old female French Bulldog was presented with a mass at the base of the heart, detected by X-ray and echocardiography. Clinical abnormality included abdominal retention by
ascites. Radiation therapy was performed for 5 weeks. The mass volume didn’t change during the radiotherapy. The condition became worse and the dog died 6 months after the initial
presentation and necropsy was performed. Grossly, the mass, 12.5 × 6.5 × 6.0 cm in size, was found at the base of the heart. Histopathological examination revealed that cardiac mass was
composed of alveolar, bundle and diffuse proliferation of neoplastic cells. Most of the neoplastic cells showed a spindle morphology; in some areas small round or polyhedral neoplastic cells
were observed. Occasional cartilage metaplasia was seen multifocal in the mass, and it was surrounded by the sarcomatoid proliferation. Electron microscopy revealed a few neuroendocrine
granules in the cytoplasm of spindle and polyhedral neoplastic cells. Metastatic cells in the lungs which had not irradiated demonstrated typical morphology of aortic body tumors. Based on
these findings, the case was diagnosed as an aortic body carcinoma with sarcomatoid morphology and chondroid metaplasia.

Abstract
A 3.5-year-old female Chihuahua was presented with complaint of neck pain, intermittent
cough and dysphagia. Physical examination and diagnostic imaging of neck region revealed a
solid and highly vascularized mass involving the retropharyngeal region. Histologically,
the mass showed an atypical zellballen pattern which comprised of high density of type I
chief cells with high nuclear cytoplasmic ratio and separated by delicate fibrovascular
stroma. Immunoreactivity for neuroendocrine markers was diffusely positive in cytoplasm of
tumor cells. Disseminated tumor emboli in external jugular vein were detected 6 months
after initial surgery. An electron microscopic study revealed numerous electron-dense
intracytoplasmic neurosecretory granules. Based on these findings, carotid body carcinoma
was diagnosed.
