摘要: A 10-month-old male beagle dog had a renal mesenchymal tumor. The tumor tissue invaded into the adjacent in an open-finger-like pattern, and entangled normal glomeruli tubules. In most parts, mass showed myxoid pattern around blood vessels, other small fascicular pattern. cells were spindle or oval shape densely basophilic nucleus scant pale cytoplasm. Immunohistologically, mostly positive for S-100 myoglobin, partially Factor VIII reactions. These findings suggest that have ability to differentiate several kinds of cells.
