10,090 dissections of dogs exhibited 2631 neoplastic processes of which 309 involved the heart in the form of eu- and heteropic tumours. The most common primary and/or secondary heart tumour type was hemangiosarcoma (n = 187), followed by paraganglioma (n = 46), carcinoma (n = 33), malignant lymphoma (n = 12), thyroid heart base tumour (n = 9), melanoma (n = 7), mast cell tumour (n = 3) and blastoma (n = 2). The tumour diagnoses were immunohistochemically proved by various antibodies to cytokeratins, vimentin, GFAP, NSE, von Willebrand factor, CD3, CD45RA, S100, thyroglobulin as well as histochemically with argyrophilic, Fontana-Masson and heterochromatic reactions. The odds ratio (OR) for breed and tumour prevalences were determined: German shepherds showed the highest OR for hemangiosarcomas and boxers for paragangliomas.

Functioning paraganglioma and gastrointestinal stromal tumor (GIST) are uncommon tumors that occur mostly in a sporadic and isolated form, occasionally as components of multiple neoplasia syndromes, either separately or together. Separately, they occur in several inherited syndromes including multiple endocrine neoplasia 2, and the GIST, lentigines, and mast cell tumor syndrome. Together, they are variably prominent components of three syndromes: the familial paraganglioma and gastric GIST syndrome, neurofibromatosis type 1, and the Carney triad. The two former conditions are inherited as autosomal dominant traits; the latter does not appear to be inherited and affects young women predominantly. This article reports the nonfamilial occurrence of functioning paraganglioma and GIST of the jejunum in 3 women, 1 young (22 years) at initial presentation. The occurrences were unexpected because of the infrequency of the tumors. The neoplasms, respectively, did not show germline SDHA, SDHB, SDHC, and SDHD, and KIT mutations associated with familial paraganglioma and familial GIST. The paraganglioma-jejunal GIST combination may be the harbinger of a rare genetic syndrome, a variant of the Carney triad or the paraganglioma-gastric stromal sarcoma syndrome, or be coincidental.

We describe a pulmonary mast cell tumor in a subsistence-harvested free-ranging Pacific walrus (Odobenus rosmarus divergens). Neoplastic cells effacing a focal area of pulmonary parenchyma were characterized by rare metachromatic granules and positive staining for C-kit. We also report co-occurrence of a peribronchial mass with a morphologic and immunohistochemical profile compatible with paraganglioma.
