We report two extremely rare cases of primary malignant fibrous histiocytoma (MFH) of the gallbladder. The first case occurred in a 70 year old woman who presented with a large tumor of the gallbladder and multiple liver metastases. The second case involved a 74 year old man with a small submucosal tumor of the gallbladder and a single large liver metastasis. Histologically, these tumors consisted of spindle cells in a storiform pattern intermingled with bizarre giant cells. Both of these patients died of liver failure 3 months post-operatively.
