Malignant melanoma is one of the most common and aggressive tumors in the oral cavity of dog. The tumor has a poor prognosis, and methods for diagnosis and prediction of prognosis after treatment are required. Here, we examined metabolite profiling using gas chromatography-mass spectrometry (GC-MS) for development of a discriminant model for evaluation of prognosis. Metabolite profiles were evaluated in healthy and melanoma plasma samples using orthogonal projection to latent structure using discriminant analysis (OPLS-DA). Cases that were predicted to be healthy using the OPLS discriminant model had no advanced lesions after radiation therapy. These results indicate that metabolite profiling may be useful in diagnosis and prediction of prognosis of canine malignant melanoma.

A 7-year-old, miniature dachshund was referred for examination and treatment of persistent anorexia, deep yellow-coloured urine and leucocytosis. The clinical sign of jaundice, results from a serum biochemistry profile and ultrasonographic images suggested a biliary tract obstruction. A cholecystectomy was performed to remove the obstruction. Histopathological assessment of the resected gallbladder and partial common bile duct indicated diffuse large B-cell lymphoma. Twelve days after the initial operation, a second procedure was performed due to bile leakage into the abdominal cavity. Chemotherapy was administered twice after the second operation but discontinued, because the dog showed adverse effects. The dog is still alive 24 months after the surgery. To the authors’ knowledge, this is the first description of canine gallbladder lymphoma.

A 9-year-old spayed female cat was examined for cheek skin drainage. The skin lesion did not respond to medical therapy; thereafter, facial deformity developed. A computed tomography revealed an intranasal mass and maxillary osteolysis. The mass was histopathologically diagnosed as suppurative granulomatous inflammation caused by filamentous bacteria. The lesion responded well to radiation therapy. Although actinomycosis was suspected histopathologically, no actinomycetes were detected in the nasal lesion by a bacterial culture conducted at a commercial laboratory. The submandibular lymph node and subcutaneous tissue exhibited swelling. Microbiological examination and genetic analysis based on 16S rDNA gene sequence revealed that Nocardia spp. were isolated from both lesions.

An 11-year-old cat presented with nasal discharge and lacrimation and was diagnosed with nasal lymphoma. Although the cat showed favorable progression after undergoing chemotherapy, CT imaging demonstrated enlarged pulmonary nodules caused by Toxoplasma gondii. Following the cessation of chemotherapy, the cat was prescribed clindamycin hydrochloride for toxoplasmosis treatment; however, the cat developed kidney lymphoma and died. No T. gondii organisms were observed in the whole body necropsy specimens. It is known that immunocompromised human patients, including those who undergo chemotherapy, are considered at risk for toxoplasmosis. However, the risk of developing toxoplasmosis in cats undergoing chemotherapy is currently unknown. Findings from this case report suggest that cats with chemotherapy-resistant pulmonary masses might have a T. gondii infection rather than metastatic disease.

A 4-year-old, male Bernese mountain dog was evaluated for a 1-year history of right hemiparesis. Computed tomography revealed a large hypoattenuating mass severely deforming the C5 vertebral arch, invading the C6 spinal canal, and causing spinal cord compression. The signal characteristics of magnetic resonance imaging indicated a lesion composed of adipose tissue. The mass was removed via right hemilaminectomy, and histopathological examination confirmed it was an infiltrative lipoma. The compressive lesion remained unresolved, so the dog underwent a second operation, after which he regained some ambulatory function. Although postoperative adjunctive radiation therapy was performed, the dog died 201 days after the first operation.

We analyzed the status of tumor development in dogs by breed based on tumor cases that presented to the Department of Veterinary Pathology of the Gifu University for diagnostic examinations over eight years (2005–2012). We also calculated the crude incidence of tumors in dogs by breed based on the results of a survey conducted in 2011 in Gifu Prefecture. The most common sites of tumor development included the skin, digestive organs, and mammary glands. Smaller dogs showed a tendency to have a higher incidence of breast tumors. We thus identified dog breeds with a higher crude incidence of tumors (Bernese mountain dog, golden retriever, corgi, etc.) and those with a lower crude incidence of tumors (Pomeranian, poodle, Chihuahua, etc.). Unlike the current trends for domestic dogs in the US and Europe, Japan has a higher number of small dogs as pets; it is therefore necessary to develop a policy for canine cancer specific to Japan.

A 7-year-old cat was referred with pelvic limb ataxia. Radiography and CT revealed bone resorption of the L1 vertebral arch, and myelography identified a compressive extradural lesion. The mass was surgically removed and histopathologically diagnosed as giant cell osteosarcoma. Three years later, the recurrent tumor resection and vertebral fixation were performed. Six months later, vertebrectomy was performed to radically excise the recurrent mass and a titanium spinal cage was placed. The cat is alive approximately 5 years after the first surgery. This case report describes vertebrectomy and vertebral body replacement as a radical treatment for feline vertebral osteosarcoma.

A 2.5-year-old male French Bulldog was evaluated for seizures. Cranial magnetic resonance imaging (MRI) suggested a glioma in the left piriform area. Radiation therapy (RT) and continuous chemotherapy were administered. Although the lesion had regressed significantly 2 months after RT, a follow-up MRI revealed meningeal enhancement in the left piriform area, which expanded further, with hydrocephalus, by day 310 (8 months after RT). Because of the poor prognosis, the dog was euthanized on day 356 and necropsy was performed. Histopathological examination confirmed anaplastic oligodendroglioma with leptomeningeal dissemination. This case suggests that the possibility of leptomeningeal dissemination and hydrocephalus should be considered even after RT and chemotherapy for anaplastic oligodendroglioma.

Aspergillus udagawae and A. viridinutans are members of the section Fumigati; both cause invasive aspergillosis in humans. These two Aspergillus species are discriminated from A. fumigatus by molecular methods. Herein, we report two cases of feline orbital aspergillosis, one caused by A. udagawae and the other by A. viridinutans. To our knowledge, Case 1 represents the first reported case of treatment of A. udagawae with a high dosage of itraconazole, and Case 2 represents the first reported case of A. viridinutans infection associated with sarcoma. Identification of the etiologic agents of these cases was confirmed by comparative analyses of the sequences of β-tubulin-encoding genes. With the spread of non-fumigatus aspergillosis, increasing emphasis should be placed on molecular identification of the infecting Aspergillus species and the use of in vitro drug susceptibility tests to ensure the selection of appropriate antibiotics.

MicroRNA-145 (miRNA-145; miR-145) is aberrantly expressed in most of human cancers and plays a significant role in carcinogenesis and cancer progression. In the current study, we focused on how miR-145 plays a role in canine and human malignant melanomas. MiR-145 was significantly downregulated in canine malignant melanoma tissues and canine melanoma cell lines, as well as human melanoma cell lines tested. The ectopic expression of miR-145 showed a significant growth inhibition in both canine and human melanoma cells tested, and the effect was achieved partly by suppressing c-MYC in canine melanoma LMeC and in human melanoma A2058 and Mewo cells. At the same time, a suppressive tendency on cell migration in canine melanoma KMeC cells and significant suppression of cell migration in human melanoma A2058 cells by suppressing FASCIN1 were also found. These findings suggest that miR-145 acts as a tumor suppressor in both canine and human malignant melanomas.
