  • An 8-year-old, female Pointer dog was presented with weight loss, hematochezia, and dyschezia. For the diagnosis, physical examination, complete blood counts, serum chemistry, radiography, ultrasonography, computed tomography, colonoscopy, cytology and histopathological examination were performed. The complete blood counts and serum biochemistry results were within the reference range. Ultrasonographic findings were presented with the thickened wall of the colon and rectum. Colonoscopy revealed irregular and ulcerated mucosal surface, mass and luminal narrowing of colorectal lesions. There were thickened wall and contrast enhancement of the lesion in colorectal region on the computed tomography. The cytologic examination suggested the adenocarcinoma. Postmortem histopathologic examination revealed adenocarcinoma. Based on these findings, the dog was diagnosed with annular colorectal adenocarcinoma.

  • Objective: To explore the clinical manifestations and imaging characteristics of gliomatosis cerebri to raise the awareness and improve its diagnostic accuracy for patients. Materials and Methods: Clinical data, imaging characteristics and pathological examination of 12 patients with GC from Jan., 2008 to Jan., 2012 were analyzed retrospectively. Results: Patients with GC were clinically manifested with headache, vomiting, repeated seizures, fatigue and unstable walking, most of whom had more than 2 lesions involving in parietal lobe, followed by temporal lobe, frontal lobe, periventricular white matter and corpus callosum. Magnetic resonance imaging (MRI) showed diffuse distribution, T1-weighted images (T1WI) with equal and low signals and T2-weighted images (T2WI) with bilateral symmetrical high diffuse signals. There was no reinforcement by enhancement scanning and signals were different in diffusion-weighted images (DWI). The higher the tumor staging, the stronger the signals. Pathological examination showed neuroastrocytoma in which tumor tissues were manifested by infiltrative growth in blood vessels and around neurons. Conclusions: In clinical diagnosis of GC, much attention should be paid to the diffuse distribution of imaging characteristics, incomplete matching between clinical and imaging characteristics and confirmation by combining with histopathological examination.

  • An elective laparoscopic ovariectomy on a healthy dog revealed a cystic structure in the left ovary. The surgical procedure was successful. Histopathological examination showed the presence of a teratoma adjacent to the ovary. To the best of the authors' knowledge, this is the first reported case of an ovarian teratoma removed by laparoscopic ovariectomy in a dog by using a multiport laparoscopic ovariectomy technique.

  • Plasma cell granuloma of the lung is very rare and most commonly detected in routine chest films. The prognosis of this disease is usually good with surgical resection. Recently, we experienced a case of this, the diagnosis of which was confirmed by postoperative histopathological examination. The operation was right upper lobectomy under the impression of benign tumor of the lung. The postoperative course was uneventful and the patients was discharged without any complication. Now we report this with literature reviews.

  • Squamous cell carcinoma of the skin was diagnosed in an 11-year-old, Australian shepherd dog with a hard mass on the right rump area. On histopathological examination of the tumor showed laminated keratin "pearls" surrounded by proliferated squamous cells, and mitotic figures. The dog was treated by surgical excision and chemotherapy with vinblastine sulfate, cyclophosphamide and prednisolone for 4 weeks. The tumor was effectively treated with a combination of surgery and chemotherapy.motherapy.

  • We report a rare case of vaginal amelanotic melanoma. Malignant melanomas are cutaneous and extracutaneous tumors that arise from embryological remnants of neural crest cells/melanocytes. Amelanotic melanomas at such rare locations can be misdiagnosed both clinically and radiologically. Therefore, histopathological examination and immunohistochemistry are mandatory for the diagnosis of these tumors. We diagnosed this case using histopathology and confirmed the diagnosis based on the presence of immunohistochemical markers human melanoma black 45 (HMB45) and S-100.

  • The incidence of diastematomyelia associated with teratoma is extremely rare. We present a case of sacrococcygeal teratoma in a neonate with split spinal cord malformation[SSCM]. Magnetic resonance imaging[MRI] showed a heterogenous mass lesion with cyst in the sacrococcygeal region and multiple spinal anormalies [diastematomyelia, tethered cord, hydromyelia, and hemivertebrae]. The mature teratoma was confirmed on histopathological examination. In SSCMs, the potential for coexisting congenital anomalies at separate levels of the spinal cord must be considered in radiological investigations.

  • A 3.5kg, 3-year-old castrated male Japanese domestic cat withpelvic limb ataxia and dysuria was referred to the Veterinary Medical Center of the Tokyo University. On the neurologic examination findings, both pelivic had a LMN paresis. The cat was FeLV positive and FIV negative. Radiographic findings did not identify the spinal lesions. In magnetic resonance images(MRI) of the lumbar spinal cord, the cat had the lesions in the lumbar(L) 1 and L3, characterized by hyperintensity on a transverse T2-weighted and T1-weighted images, and contrast enhancement was evident. The mass removed by dorsal laminectomy. Histopathological examination of the mass revealed spinal lymphoma. Three weeks after the surgery, the cat administered chemotherapy protocol for lymphoma by current protocol. Two weeks after chemotherapy, the cat had a metastasis to bone marrow and died.

  • An 11 kg, 7-year-old male pug dog with lameness and tumor of the 2-3rd interdigital portion of the right forelimb was referred to the Veterinary Medical Center of the Tokyo University. On the clinical examination findings, the tumor size was $3{\times}3 cm but alopecia and necrosis were not found. On the radiological findings, a bone lysis was found in the phalanges of digit II of the right forelimb but pulmonary metastasis was not found. The mass was removed with metacarpal bone. Histopathological examination of the mass revealed highly differentiated hemangiopericytoma. Two weeks after the operation, the dog was irradiated by orthovoltage radiation. The source of irradiation was 300 kV, 4mA, 4Gy and a focal spot to skin distance of 40 cm using 1.0 Cu, 1.0Al filter. The radiation therapy was performed twice a week for 5 weeks. The dog showed no recurrence and no metastasis. It was thought that the surgery and radiation therapy treatment was quite a useful method to treat a canine heman-giopericytoma.
