Undifferentiated testicular pleomorphic sarcoma: A case report

Figure 1 Hematoxylin and eosin-stained pathology slides. A: Tumor cells show patchy positivity for vimentin and are negative for other markers such as pankeratin, CK5/6, GATA binding protein 3, etc. These findings are consistent with undifferentiated pleomorphic sarcoma. Magnification 10 ×; B: Final hematoxylin and eosin (HE) stained pathology slides showing pleomorphic sarcoma (Federation of the French Cancer Centres grade 3), 9.5 cm in size and was limited to the testicle. The tumor cells do not invade beyond the testicular layers, as shown. The surgical margins were therefore negative. Magnification 10 ×; C: On pathologic staining with HE, sections show haphazardly growing sheetlike proliferation of spindle cells exhibiting marked nuclear pleomorphism. This morphology was consistent with a pleomorphic sarcoma. Magnification 40 ×; D: HE-stained slides showing an example of the large, bizarre, atypical cellular forms and tumor giant cells noted with the diagnosis of sarcoma. Magnification 40 ×.
