A Quantitative Study of Changes in the Human Corpus Luteum Microvasculature during the Menstrual Cycle1
Uterine MĂĽllerian adenosarcoma with histiocytic (xanthomatous) mesenchymal component
We present an endometrial MĂĽllerian
adenosarcoma in which the sarcomatous component
showed prominent nests of foamy cells that accounted
for 50% of the neoplastic mesenchyma. Such foamy cells
showed occasional cytological atypias and immunohistochemical
features of histiocytic (macrophagic
differentiation in the absence of changes that could
substantiate the presence of an inflammatory infiltration
of foamy histiocytes. These facts suggest histiocytic
differentiation from neoplastic mesenchymal cells. Such
differentiation has been reported in association with
malignant mixed mesodermal tumor, but not in
MĂĽllerian adenosarcom
