The center of the tumor was mineralized extensively, as noted in radiographic analysis and computed tomography; thus, the tumor was sectioned after demineralization. was enlarged by an amorphous mass with opaque areas, indicative of mineralization. Upon histologic examination, the mass was comprised of malignant mesenchymal cells that produced mucinous matrix. The tumor cells were positive for vimentin and COX-2, but negative for pancytokeratin; the matrix stained positively with alcian blue. Therefore, the mass was diagnosed as a renal interstitial cell tumor, with malignant features. COX-2 may be useful in the diagnosis of canine renal interstitial cell tumors, similar to its diagnostic role in humans. strong class="kwd-title" Keywords: dogs, image, immunohistochemistry, malignant, renal interstitial Rabbit Polyclonal to MLTK cell tumor In dogs, primary renal tumors are relatively uncommon, comprising 0.3C1.5% of…
