Osteoclastic giant cell carcinoma, Pancreas, Gall bladder
A 71-year-old woman was admitted to our hospital with complaints of appetite loss and icterus. Ultrasonography showed hypoechoic masses at the pancreatic head and in the gall bladder. Surgical resection of the tumors was performed and a histological examination revealed that these tumors both consisted mainly of osteoclast-like giant cells which contained 5-40 nuclei. In this paper, we report a very rare case of giant cell carcinoma (osteoclastic type) of the pancreas with gall bladder metastasis.
