A cross breed dog (6-year-old, 6 kg, intact male) was referred with hematuria. The dog had been treated for years owing to the urinary bladder calculi. On abdominal radiography, prostatic calculus was demonstrated in the prostatic area. In addition, ultrasonography and computed tomography (CT) scan would confirm that the part of calculus protruded within the prostatic urethra. The patient underwent a prostatolithotomy and traumatic prostatic urethra was carefully sutured and the omentum was filled with the prostate lumen. A crystallographic analysis of the stone showed 80% magnesium ammonium phosphate (struvite) and 20% carbonate apatite. The leakage of the urine was not observed post-operation and the hematuria improved and there was no specific problem at the 6 months follow-up.

Gastrointestinal stromal tumor (GIST) is one of the mesenchymal tumors originated from gastrointestinal submucosa. A 10 year-old, male, mixed breed dog with persistent diarrhea, anorexia and lethargy was referred to Haemaru Animal Referral Hospital. Large mass originated from the transverse colon was observed and large amount of ascites and free gas were found on abdominal radiography and ultrasonography. The ascites was septic exudate mixed with bacteria that consisted with intestinal perforation. There was no metastatic lesion. This mass was tentatively diagnosed as adenocarcinoma, leiomyosarcoma (LMS) and lymphosarcoma and surgical resection and histilogical examination were planned. However, according to owner's request, the patient was euthanized and then the necropsy was performed. About 10 cm sized mass originated from the cecum, ascending colon and transverse colon was adhered to surrounding mesentery and the perforation and large amount of ascites were observed. GIST was suspected on histopathologic examination and confirmed according to CD 117 expression in immunohistochemistry. GIST, derived from interstitial cells of Cajal, can be distinguished from LMS and leiomyoma (LM) on the basis of expression of CD117 (KIT) immunohistochemically. GIST has a different biological behavior and clinical course compared with LMS and LM, therefore definite diagnosis for GIST using immunohistochemistry is clinically important to predict the precise prognosis of the patient.

A seven-year-old Yorkshire terrier 2.1 kg was admitted with a 2 months history of sever bilateral forelimb lameness and joint instability. Examination and radiographs revealed caudal luxation of bilateral antebrachiocarpal joint. Luxation of bilateral antebrachiocarpal (ABC) joint in a toy breed dog was treated with pancarpal arthrodesis. Modified external skeletal fixator (ESF) (type IIb) with polymethylmethacrylate (PMMA) was utilized in this case. Porcine cancellous bone graft (PCBG) was inserted to fill the joint space in carpus. The clinical and radiographic assessments of joint after the surgical procedure proved that PCBG can be used a promising alternative to Autogenous cancellous bone graft (ACBG).

This study provides basic indices for the development of a pet dog's dummy. Surveys were conducted with 71 owners of small dogs weighing under 10kg as preliminary research for information on pet dogs, uses and complaints about their clothes and demographic information to investigate wearing conditions. We collected pictures of 30 products sold in 12 brands at home and abroad to analyze size, materials, and patterns and investigate the actual production conditions. The survey results on wearing conditions indicated that 'Maltese' was the breed most often raised in households. Dogs weighing 'between 3kg and 4kg' were most common. Dogs under five years of age took up 53.5%. Most of the clothes were 'S' size, followed by 'M' and 'L' Most responded, 'The overall size does not fit' as an inconvenience when worn for long. Second, most brands developed products in three sizes. The displayed details included neck and chest circumference, back length and dummy height. Cotton and artificial leather were used most often for the outer fabric, cotton for the internal filling along with wire and aluminum for some products to maintain shape and motions. Most dummies consisted of back+outer leg, belly, inner leg and sole. Sometimes, a composition line was added by the chest shape, and an incision was placed between the body and leg for breeds with thick legs. Most patterns had a composition line in the leg connected from the belly.

A 12-year-old, female mixed breed dog presented with a vaginal mass protruding outside the vulva. The patient was non-gravid, with normal defecation and urination. Serum chemistry revealed azotemia and increased alkaline phosphatase. Hematology findings were normal. Blood electrolytes showed mild hypernatremia. Ultrasonography demonstrated severely enlarged uterine horns, a uterine body with anechoic to hypoechoic fluids, and a focal hypoechoic area within the mass of the right uterine tube. On computed tomography, metastasis was not confirmed. Other computed tomography findings suggested a right ovarian cyst, an enlarged, fluid-filled uterus, and an enlarged vagina with a mass. Ovariohysterectomy, episiotomy, and vaginectomy were performed. The case was diagnosed as uterine tube adenocarcinoma, vaginal fibroma, and pyometra. This case is the first reported concurrent occurrence in dogs.

A 10-year-old intact male mixed breed dog was presented with a three-month history of massive oral mass. Physical examination revealed extending mass from the right upper gingiva. No metastasis was found at the time of presentation. Histopathologic examination of biopsied tissue from the oral mass was consistent with a neuroendocrine tumor with generalized epithelioid cells and few spindle cells. There were highly mitoses and no visible melanin granules with H&E staining. Immunohistochemical staining for Melan A was performed on section of tumor and was strongly positive. Diagnosis was made as amelanotic malignant melanoma based on histopathology with Melan A immunohistochemistry. This case study indicates that the Melan A immunohistochemical staining may be valuable to diagnose amelanotic malignant melanoma in dogs.

An 11-year-old, female, Maltese dog was presented with abdominal distension and intermittent slight lameness on left hindlimb. Palpable abdominal pain and purulent vaginal discharge were observed on physical examination. Severe leukopenia with toxic change, and azotemia, hyperphosphatemia, and hyponatremia were identified on blood profile. On radiographs and abdominal sonograms, remarkable soft tissue mass containing echogenic material deviating intestines craniodorsally compatible with pyometra. On stifle radiographs, 4-5 fragmented sesamoid bone (fabella) was identified on both stifle joint with medial patella luxation. Immediate ovariohysterectomy was performed and the patient was recovered well with normal blood work. No specific treatment was attempted to the left hindlimb showing minimal and intermittent lameness. No remarkable abnormal gait was reported for 3-month follow-up period. The fragmented lateral fabella is considered congenital multipartite of lateral fabella not related to the lameness.

A 12-year-old female mixed breed dog receiving a progesterone drug was referred for evaluation of an abdominal mass. Abdominal radiography and ultrasonography revealed a swollen uterus and an associated mass. Serum chemistry revealed hyperglobulinemia consistent with acute inflammation based on the results of serum protein electrophoresis. Fine needle aspiration of the mass guided by ultrasonography was performed for cytological evaluation. The cytological impression was consistent with adenocarcinoma. Exploratory laparotomy identified a uterine body mass, which was surgically removed for histopathology. Histology of the mass identified a uterine adenocarcinoma. Immunochemistry using anti-estrogen and progesterone receptor antibodies was performed and neoplastic cells were negative to both antibodies while some normal elements were reactive to both of them. Computer tomography demonstrated evidence of metastatic disease in the lung one week after the surgery and the dog died about 40 days after surgery.

Nasal tumors have been reported frequently in dogs and nasal discharge has been the primary presenting complaint in nasal tumor patients. A 10-year-old 7 kg male mixed breed dog was presented to the animal hospital for evaluation of severe bloody nasal discharge. After physical examination, blood examination and X-ray examination, magnetic resonance imaging (MRI) examination was also conducted. Based on MRI nasal tumor which does not extend cranial vault was diagnosed. The nasal tumor was confirmed as adenosquamous cell carcinoma by histopathological examination after necropsy. The invasive characteristics of the neoplasm were documented by MRI. MRI was very valuable diagnostic tool for identifying extracranial and intracranial tumor invasion in a small animal.

A 5-month-old female Samoyed dog was presented with primary complaints including exercise tolerance and neurological sign associated with hepatic encephalopathy. The major findings in clinical examination included an intermittent seizure, anemia, elevated pre- and post-prandial serum bile acid, hypoproteinemia and bilirubinuria. Diagnostic imaging studies revealed an intrahepatic portosystemic shunt (IPSS). The shunted vessel was successfully occluded by transvenous coil embolization. Clinical signs were gradually improved after shunt occlusion. This case is a rare case of IPSS in a large breed dog fixed by transvenous coil embolization.
