| With the purpose of shedding light on some doubts in veterinary oncology, the present article intends to compare the results of histopathological and immunohistochemical examinations of unspecific round cell neoplasia, to realize immunophenotyping of canine lymphoma cases, to establish the T or B origin of neoplastic cells, and to determine the degree of proliferation and apoptosis of lymphomas by immunohistochemistry. Of 11 animals presenting immunohistochemical diagnosis of lymphoma, five had been diagnosed as Lymphoma by HE staining of histopathological slides and six had been classified as unspecific round cell neoplasia. All cases submitted to immunohistochemical examination were T-cell lymphomas. There was a positive correlation between cell... |

| The present report describes a case of Sezary syndrome in a canine with lymphadenomegaly, generalized erithroderma, intense pruritus and disseminated cutaneous nodules and plaques. Biopsy samples were taken from cutaneous nodules and plaques and were diagnosed epitheliotropic T cell cutaneous lymphoma by histology and immunohistochemical stain. Bone marrow cytology confirms leukemia. Diagnosis of Sezary syndrome was achieved through clinical, hematological, citopathological, histopathological and immunohistochemical findings. The patient was treated with Madison-Wisconsin chemotherapy protocol, but died after two mouths of treatment. |

| A 12-year-old male English Pointer was examined due to a soft-tissue swelling at the medial canthus of the right orbital region, which was causing facial deformity. The dog had epiphora, purulent nasal discharge, epistaxis, dyspnea, and progressive weight loss. An intraoral mass was observed near the right maxillary premolars. Neoplastic disease was diagnosed based on ancillary tests, which included blood work, skull and intraoral radiographs, ocular ultrasonography and computed tomography. Histopathology revealed transitional carcinoma involving the nasal and oral cavities, maxilla, bony orbit and retrobulbar space. Nasal tumors represent approximately 2% of all tumors diagnosed in this species. Transitional carcinoma is the second most common type of... |
