Primary hepatic epithelioid angiomyolipoma: A malignant potential tumor which should be recognized

Figure 3 Histology of hepatic epithelioid angiomyolipoma. A: The tumor comprised of sheets of large polygonal cells with abundant granular eosinophilic cytoplasm (HE, × 200); B: The tumor cells were arranged radial around blood vessels (HE, × 40); Microscopic features signifying aggressive behavior were observed: C: Cytologic atypia (black arrow) (HE, × 200); D: Coagulative necrosis (HE, × 40); E: Increased mitotic count (black arrow) (HE, × 200); F: Tumors mainly consisted of epitheli¬oid cells that comprised approximately 95% of the total neoplastic mass (HE, × 40).
