  • A 9-year-old, intact female Jindo dog weighing 23 kg was presented to the Veterinary Medical Teaching Hospital of Chungnam National University with a history of two months of ocular discharge. Initial ocular examination showed a 2 cm elongated mass arising from the ventral bulbar conjunctiva of the left eye. Ocular ultrasound, performed to rule out any orbital and intraocular involvement, was negative. Thoracic radiographs and abdominal ultrasonography revealed no abnormalities. Fine needle aspiration (FNA) of mass was performed. Aspiration cytology showed the presence of a round cell population mostly characterized. A moderate amount of eosinophils was present among round cells. The mass was excised and identified hitologically as a mast cell tumor. Six months after surgical treatment, thoracic radiographs and abdominal ultrasonography did not reveal any clinical signs of local recurrence or metastatic disease.

  • An 11-year-old, castrated male Yorkshire terrier dog was presented with multiple plaques on right inguinal region. Grade II mast cell tumor was diagnosed. The dog was treated with Vinblastine and prednisone(PDS) initially. Because of poor response of the dog, CCNU was added for more aggressive treatment. After 5 weeks treatment of with CCNU, vinblastine and PDS, the lesion was improved. Moderate leukopenia was shown after 4 cycles of chemotherapy. The chemotherapy was re-administered since the patient recovered from the leukopenia. Though the same protocol was applied, no improvement of the lesion was observed. Moreover, the general body condition of the dog became worse and was euthanized by the owner's request. Necropsy was not permitted. The survival time was 330 days after start of the chemotherapy.

  • A 7-year-old female maltese dog with anorexia and vomiting for a week, and left axillary and perineal mass was admitted to Gyeongsang National University Veterinary Teaching Hospital. CBC revealed mild leukocytosis and severe anemia. Abdominal radiography revealed multiple gas opacities in upper abdomen. On ultrasonography, large amount of echogenic free abdominal fluid were detected. In addition, There are enhanced peritoneal strip sign (EPSS) indicating peumoperitoneum in the upper abdomen. Fine needle aspiration of the mass was performed and the result was mast cell tumor. Duodenal perforation caused by mast cell tumor was identified on laparotomy.

  • Skin tumors and mammary gland tumors have been shown to be the most common neoplasia in most of the strains of dogs. The risk for tumor development increases significantly with age and the prevalence and distribution are various according to individual tumors. The aim of this study is to classify histopathologically the skin and mammary gland tumors for recent two years, 2005 and 2006. A total of 128 skin and 240 mammary gland samples of dogs were selected that were submitted to National Veterinary Research and Quarantine Service and Kangwon National University from January 1, 2005 to December 31, 2006. The excised tissue were fixed in 10 percent neutral buffered formalin and processed routinely to paraffin wax. Sections were cut at $3{\mu}m$, stained with haematoxylin and eosin. The slides were examined based on the morphological criteria of M. H. Goldschmidt and W. Misdorp under a light microscope. The age of the dogs ranged from 1 to 19 years with a median of 8.7 years. The mean age of the skin and mammary gland tumors was 7.4 and 9.3 years. 47 (12.8%) were males and 259 (70.4%) were female with a male to female ratio of 0.18. Yorkshire terrier and maltese were more susceptible breeds, accounting for 44.3% of skin and mammary gland tumors. In skin tumors, epithelial, adnexal, and mesenchymal origin tumors were 18 (14.1%), 53 (41.4%), and 57 cases (44.5%), repectively. Among the epithelial, adenexal, and mesenchymal origin tumors, basal cell tumor (8.6%), sebaceous adenoma (15.6%), and histiocytoma (25.0%) were predominant in the incidence rate, respectively. In case of mammary gland tumors, 201 (83.8%) were benign and 39 (16.3%) were malignant with a benign to malignant ratio of 5.15. The most frequent mammary gland tumor was benign mixed tumor (35.0%) followed by mammary adenoma-complex type (31.7%).
