title: Mixed mesodermal tumor of urinary bladder: a light and electron microscopic study.
abstract: Light and ultrastructural findings in a mixed mesodermal tumor of the urinary bladder are reported. The mesenchymal component of the tumor contained undifferentiated mesenchymal cells and cells with chondroblastic differentiation. The neoplastic chondrocytes displayed an abundance of cytoplasmic microfilaments and had a scalloped cell surface.
