Osteoclast-type giant cell tumor of the pancreas. Case report.

Local resection of a 1200 g, apparently inoperable pancreatic mass was performed on an elderly woman. Because she survived for more than 6 years without recurrence or metastases, the specimens were reviewed. They were compatible with giant cell tumor of osteoclast type. Correct diagnosis of this unusual tumor is important because of its seemingly favorable prognosis.
