Última Comparative study of histopathology and immunohistochemistry of indefinite round cell cutaneous tumors and characterization of canine lymphoma Arq. Bras. Med. Vet. Zootec. Machado,L.H.A.; Palumbo,M.I.P.; Zahn,F.S.; Amorim,R.L.; Farias,M.R.; Werner,J.; Torres Neto,R.; Rodrigues,J.C.; Oliveira,F.C.. 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...

Vet. Zootec. Palumbo,M.I.P.; Rossetto,V.J.V.; Torres Neto,R.; Brandão,C.V.S.; Amorim,R.L.; Fabris,V.E.; Machado,L.H.A.. Several types of tumors affect dogs' skin. Simultaneously occurring neoplasms with different histological patterns might be rarely present in the same animal. This paper describes the occurrence of epitheliotropic cutaneous T-cell lymphoma and melanoma in a dog. The animal had nodular lesions in the abdominal region and serpiginous plaques on the dorsal region of the trunk. Cytology evidenced malignant fusiform cells from the abdominal lesions as well as few round cells from the dorsal. The histopathological examination of the abdominal lesions showed dermis with polygonal to spindle-shaped neoplastic cells. The lesion of the dorsal region evidenced neoplastic round cells with generally distinct cell borders and a moderate amount of eosinophilic cytoplasm....

Bras. Med. Vet. Zootec. Loures,F.H.; Conceição,L.G.; Lauffer-Amorim,R.; Nóbrega,J.; Costa,E.P.; Torres Neto,R.; Clemente,J.T.; Vilória,M.I.V.; Silva,J.C.P.. ABSTRACT Soft tissue sarcomas (STS) comprise a heterogeneous group of malignancies derived from extra-skeletal mesenchymal tissues that may show similar histopathological changes. Histopathologic patterns suggestive of perivascular wall tumors (PWT) and peripheral nerve sheath tumors (PNST) have been described. This study investigated the histogenesis in a series of 71 cases of canine STS that showed morphological compatibility with what is described for PWT and PNST. Immunohistochemistry analysis were done to CD56, S100, SMA, Desmin, Von Willebrand Factor, NSE and GFAP. Twenty-one cases (29.6%) showed histopathologic features compatible with PWT, 23 cases (32.4%) with PNST and 27 cases (38.0%) shared both histopathological features. By...
