The tumor is of interest for two reasons： first, there still exists considerable dispute as to the origin of the lesion and recent reports reveal that the condition is more malignant than had previously been supposed. Although cases of adamanti- noma located to the axial skeleton have been reported, this is the first case of adamantinoma located to pelvic bone in Iran. Here we present the clinical, radiological ＆ histopathological features of a 19 year-old male with painful lesion located to the right pelvic bone which was morphologically and immunohistochemically diagnosed as adamantinoma. In general, metastasis is seen in 15%-20% of patients. The spread can occur to regional nodes, lung and infrequently to skeleton, liver and brain . Several weeks after surgery, our patient＇s condition gradually worsened. A CT-scan of abdomen revealed widespread liver metastasis and the patient died due to acute liver failure. This case demonstrates that the mortality rate from adamantinoma is not always low.展开更多
