Article: Auricular Rhabdomyosarcoma in a Rat[Show abstract] [Hide abstract]
ABSTRACT: An ear (auricular) neoplasm from a 1-year-old male rat was removed surgically and examined histologically. Macroscopically, the neoplasm was firm, white and measured (0.5 x 0.5 cm). Microscopically, the neoplasm was expansile, non-encapsulated, and composed of large, pleomorphic, polygonal to spindle-shaped cells containing multiple nuclei. Using immunohistochemical and chemical stains, the neoplastic cells were positive for vimentin, myoglobin, phosphotungstic acid haematoxylin and desmin, but had no immunoreactivity for cytokeratin or alpha-smooth muscle actin. On the basis of histopathological, immunohistochemical and histochemical stains, a diagnosis of auricular rhabdomyosarcoma was made. Although reported infrequently in human, this is, to the author's knowledge, the first report that describes the detailed gross, histopathological, histochemical and immunohistochemical findings of auricular rhabdomyosarcoma in a rat.Journal of Veterinary Medicine Series A 07/2006; 53(5):246-8.

ABSTRACT: In this study, the authors have analyzed equine skin samples received at the Department of Pathology and Forensic Veterinary Medicine of the Faculty of Veterinary Scienc, Szent István University, between January 2000 and April 2007, from the aspect of breed, gender, age and anatomical region. During the histopathological examination the 85 samples were divided into two groups: skin tumours 62 (72.94%) and tumour-like lesions 23 (27.06%). The most frequently diagnosed tumour proved to be equine sarcoid (43.55%), followed in order by papilloma (17.74%), melanoma (16.13%), dermatofibroma (11.30%), squamosus cell carcinoma (4.83%) and cutan hemangioma (3.23%). The most frequently diagnosed tumour-like lesion proved to be perivascular dermatitis (50%), followed in order by eosinophilic dermatitis (50%) and bothryomycosis (20%). The authors compare the results of the study with the statistical results of the foreign studies. The authors detail the frequency of the sarcoid, its macro- and microscopical morphology, clinical characteristics, as well as the existing therapeutic methods.Magyar Allatorvosok Lapja 01/2007; 129(9):515-524. · 0.19 Impact Factor
