Definition / general
  • High grade endometrial adenocarcinomas with a malignant giant cell component and aggressive clinical course (Int J Gynecol Pathol 1991;10:260)
  • Recent case series (Am J Surg Pathol 2010;34:1132), but overall very few cases reported
  • Rare, high grade tumor with poorly cohesive sheets and nests of bizarre, pleomorphic and multinucleated giant cells and mononuclear tumor cells
  • In contrast to osteoclast-like giant cell tumors, giant cells are clustered, and not evenly distributed
  • Usually coexists with endometrial adenocarcinoma
  • Also peritumoral and intratumoral inflammatory cell infiltrate of lymphocytes, plasma cells, eosinophils and neutrophils with emperipolesis

but most of the tumor grows as
solid sheets of anaplastic cells,
many of which are multinucleate
