Histological features of pancreatic undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) under 100X (H&E, a). UC-OGC associated with poorly differentiated ductal adenocarcinoma component under 100X (H&E, b). The UC-OGC composed of anaplastic carcinoma and intermixed with pleomorphic neoplastic mononuclear cells and multinucleated osteoclast-like giant cells under 200X (H&E, c and d). Osteoclast-like giant cells of the tumor were stained positive for CD68 (IHC, e). Staining was positive for CK7 diffusely in the PDAC component of the tumor (IHC, f)
