A 12-year-old, spayed female, Toy-poodle dog presented in progressive, pruritic carpal mass and mandibular papule. The skin lesions and enlarged superficial lymph nodes were surgically removed. According to histopathology and immunohistochemistry, the patient diagnosed as cutaneous epitheliotropic T-cell lymphoma with lymph node metastasis. Chemotherapy with L-asparaginase, lomustine and prednisolone was initiated. The patient deteriorated despite treatment and was admitted to the hospital. Blood tests revealed significant leukocytosis. Circulating large lymphocytes with convoluted and cerebriform nuclei seen in peripheral blood led to presumption of Sézary cells. Thus, considering skin, lymph nodes and blood involvement, Sézary syndrome was diagnosed.

A 7-year-old spayed female Shih Tzu dog was presented for evaluation of recurrent hypoglycemia. Serum insulin levels during hypoglycemia were 35.3 µIU/mL. Ultrasonography and computed tomography showed a mesenteric nodule between the kidney and the portal vein, but no pancreatic mass was observed. During surgery, the nodule had neither anatomical adhesions nor vascular connections to the pancreas. Pancreatic inspection and palpation revealed no abnormalities. Hypoglycemia improved after resection of the nodule. Histopathological examination confirmed the nodule to be an islet cell carcinoma. Although extremely rare, ectopic insulinoma should be considered as a possible cause of insulininduced hypoglycemia in dogs.

An 11-year-old spayed female Maltese dog presented with mass in oral cavity. On conscious oral examination, the right maxillary canine tooth was not visible, and a lesion has been suspected of mass existed in canine tooth area. The adjacent maxillary first premolar was buried in the lesion, with a little part of the tooth exceptions. On radiographic examination, the canine tooth was buried horizontally in the lesion, and the root part was adjacent to the first premolar tooth. Extraction was performed for a treatment. When the lesion was incised, the canine tooth was horizontal with the concave surface facing the palatal, and formed double teeth by fusing with the premolar tooth at the roots parts of the teeth. This report described the double teeth in the dentigerous cyst rarely reported in dogs.

Among benign proliferation of the urinary bladder, polypoid cystitis is a rare disease in dogs. It is characterized by epithelial proliferation, chronic inflammation in lamina propria, and development of a polypoid mass or masses without evidence of neoplasia. This report describes histopathologic features of polypoid cystitis in dog. A 10-year-old spayed female shihtzu-dog was presented with two-month history of hematuria. Abdominal ultrasonography confirmed the thickened bladder wall and calculi in both kidneys. Surgical biopsy sample was taken from the thickened bladder mucosa for the histopathologic examination. The mass was covered with irregular hyperplastic transitional epithelium with the projection into the lumen in multifocal areas as well as many Brunn's nests in lamina propria. Many inflammatory cells such as lymphocyte, plasma cell, and macrophage and few neutrophils were occupied in lamina propria and submucosa. Proliferated fibrous tissues in lamina propria were clarified by using special staining methods. These collagens were stained blue with Masson's trichrome and red with van Gieson, but negative for alcian blue. Based on the clinical, gross, and histopathologic examinations, this case was diagnosed as polypoid cystitis in a dog. In our best knowledge, this is the first report of polypoid cystitis in dog in Korea.

A fifteen-year-old spayed female Pug was referred to Veterinary Medical Teaching Hospital of Seoul National University. The clinical sign was a restriction of the movement of the headneck and acutely presented for 5 days ago. On the basis of physical, laboratory and radiological examinations, the dog was diagnosed acute torticollis (wry neck). We treated two times the dog with acupuncture therapy for 2 weeks. The acupuncture points BL10, BL11, LU7 and SI3 were used. When the dog was rechecked at three weeks after the therapy, torticollis was disappeared and voluntarily head movement found. Thus, it is suggested that traditional acupuncture might be effective therapy for acute torticollis.

A 6-year-old, spayed female Miniature Pinscher dog with chronic vomiting lasted for 7 weeks was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Physical examination, complete blood counts, serum chemistry, gastroscopy, upper gastrointestinal series, endoscopic biopsy and histopathological examination were performed for the diagnosis. The complete blood counts and serum biochemistry revealed no remarkable effect to the patient's general condition. Gastroscopy revealed erosion, erythema in mucosal surface of gastric lesions and endoscopic biopsy performed. No significant findings in upper gastrointestinal series were observed, and histopathologic examination revealed infiltration of lymphocyte in the gastric mucosa. Based on these findings, the dog was diagnosed with lymphocytic gastritis. The dog were treated by metronidazole and ranitidine with hypoallergenic diet, and then the patient showed no vomiting or other complications.

A 7-year-old spayed female Shih-tzu dog with 4-month history of anorexia and weight loss was diagnosed with splenic hemangiosarcoma. One week after splenectomy, the dog developed severe, multifocal, coalescing erosive and ulcerative dermatosis with epidermal collarettes and crusts on the dorsal trunk. The dog was prescribed systemic antibiotics comprising cephradine and enrofloxacin postoperatively. Histopathological examination of skin biopsies from haired skin lesions revealed changes consistent with pemphigus foliaceus (PF). Tentative diagnosis for this patient was pemphigus-like drug reaction resulting from cephradine treatment. However, given the dog's history of hemangiosarcoma, paraneoplastic pemphigus (PNP), a rarely reported cancer-related pemphigus in dogs, was also considered for tentative diagnosis. Significant clinical remission of dermal lesions was achieved with four weeks of prednisolone and mycophenolate mofetil (MMF) treatment. Drugs were gradually tapered and eventually discontinued with concurrent reduction of dermal lesions, and no further recurrence was noted.

A 13-year-old spayed female Miniature Schnauzer was presented with complaints of intermittent syncope. Pericardial effusion was confirmed based on the physical examination, thoracic radiographs and echocardiography. Subsequently, prompt pericardiocentesis was performed. Clinical abnormalities were immediately improved after pericardiocentesis. However, the clinical signs associated with acute collapse recurred. After the second pericardiocentesis, thoracic radiographs revealed pleural effusion, and the clinical signs resolved rapidly. The dog underwent pleural aspiration. Analysis of pleural fluid revealed almost similar features as the previous pericardial fluid. It was possible that a pericardial-pleural fistula was created during the pericardiocentesis. The pericardial and pleural effusion disappeared after the procedures.

An 11-year-old, spayed female poodle presented with fever and shifting lameness. Physical examination revealed hyperthermia ($40.6^{\circ}C$), and proteinuria was detected upon urinalysis. Increased neutrophils (83%) and decreased viscosity were revealed upon synovial fluid analysis. Serum antinuclear antibody was positive at 1 : 80. Based on these findings, the dog was diagnosed with systemic lupus erythematosus. Immunosuppressive therapy was initiated with prednisolone and cyclosporine, and the condition was markedly improved after the treatments. This case report describes the clinical and laboratory findings, imaging characteristics and successful outcomes after prednisolone plus cyclosporine therapy in a canine systemic lupus erythematosus case.

A 10-year-old spayed female Cocker spaniel weighing 6.64 kg was presented with a sign of syncope. Electrocardiographic findings revealed pathologic atrioventricular (AV) block alternating 3rd degree AV block, non-responsive to atropine. Before pacemaker implantation, several anti-hypertensive medications were administered, but there was no improvement. After pacemaker implantation, the heart rate and systemic arterial systolic blood pressure were immediately improved. This is the first report on the resolution of an AV block and malignant systemic hypertension after a pacemaker implant in veterinary medicine.
