Canine Cutaneous Mast Cell Tumor: Morphologic Grading and Survival Time in 83 Dogs
Eighty-three cutaneous mast cell tumors in the dog were classified morphologically into three grades. The neoplasms were excised surgically, and the dogs were followed for 1500 days. Comparison ofExpand

  • 1 January 1990
TLDR
Canine extraskeletal osteosarcomas are extremely rare tumors that develop in the visceral organs and are found in the adrenal gland, eye, gastric ligament, ileum, kidney, liver, spleen, testicle, and vagina. Expand
Histologic and Immunohistochemical Studies of Granular Cell Tumors in Seven Dogs, Three Cats, One Horse, and One Bird

  • 1 March 1993
TLDR
Results of these immunocytochemical studies suggest that granular cell tumors, like tumors composed of rhabdoid cells, clear cells, and oncocytes, can have similar morphologic features but be of different cellular origins. Expand
Canine Ovarian Neoplasms: A Clinicopathologic Study of 71 Cases, Including Histology of 12 Granulosa Cell Tumors
TLDR
In a retrospective study of 71 primary ovarian tumors in the dog, epithelial tumors (46%) were more common than sex cord stromal (34%) and germ cell tumors (20%) and adenocarcinomas (50%) had the highest rates, and distant metastasis was more common in malignant teratoma. Expand
Feline Melanoma: A Comparative Study of Ocular, Oral, and Dermal Neoplasms
TLDR
Results of this study indicate that in the cat, ocular melanomas are more common than oral and dermal melanomas, and ocular and oral melanomas arc more malignant than dermal metastasis, with higher rates of mortality and metastasis. Expand
A Clinicopathologic, Histologic, and Immunohistochemical Study of Mixed Germ Cell-Stromal Tumors of the Testis in 16 Dogs
TLDR
Immunocytochemical studies of 18 mixed-cell tumors, testes from five clinically normal dogs, six seminomas, and six Sertoli cell tumors revealed that neuron specific enolase (NSE) and vimentin were useful in demonstrating the dual population of the mixed cell tumors by differential staining of the germ cells and SERToli cells.

Hepatobiliary Neuroendocrine Carcinoma in Cats: A Clinicopathologic, Immunohistochemical, and Ultrastructural Study of 17 Cases
TLDR
Hepatobiliary neuroendocrine carcinoma was diagnosed in 17 cats in a period of 10 years, and in this cat, ultrastructural studies showed neurosecretory granules leading to the diagnosis of Zollinger-Ellison syndrome. Expand
Canine Hepatic Neuroendocrine Carcinoma: An Immunohistochemical and Electron Microscopic Study
TLDR
The results show that neuro endocrine markers commonly used in humans can be used for the diagnosis of hepatic neuroendocrine carcinoma in dogs, preferably a panel of synaptophysin, chromagranin-A, and NSE because chromogran in-A alone is not as useful in dogs as in humans. Expand
A Morphologic and Immunocytochemical Study of Hepatic Neoplasms in Cats
  • A. Patnaik
  • Biology, Medicine
  • Veterinary pathology
  • 1 September 1992
TLDR
The frequency of different types of hepatic neoplasms in cats varied from that seen in dogs and human beings, but the morphologic features were comparable. Expand
Canine Ovarian Tumors of Germ Cell Origin
Fourteen ovarian germ cell tumors were diagnosed in the dog—seven dysgerminomas and seven teratomas. Six of the teratomas had immature components and were judged malignant; three had metastasized.Expand
