We previously reported that dynamic contrast-enhanced MRI parameters and time–signal intensity curves (TICs; also known as contrast index curves) are useful for the differential diagnosis of jawbone lesions. In particular, odontogenic fibroma and ossifying fibroma, which possess similar histopathological features (i.e., a mixture of hard and soft tissue components), display unique TIC patterns, and we consider that the TIC patterns of these lesions reflect their hard and soft tissue components. Therefore, fibrous dysplasia, which contains fibrous tissue and immature isolated trabeculae composed of woven bone, is expected to display an interesting TIC. The purpose of this study was to assess the utility of TICs for differentiating between the abovementioned lesions, which have similar histopathological components. 相似文献

INTRODUCTIONSkeletal muscle metastases from carcinomas, especially to intercostal muscles, are rare. Most metastatic chest wall tumors from hepatocellular carcinoma (HCC) result from disseminations through needle tracts of intrahepatic HCC treatments.PRESENTATION OF CASEWe report the case of a 65-year-old man with chronic viral hepatitis B whose intrahepatic lesions were stabilized by repeated radiofrequency ablations and transcatheter arterial chemoembolization. Follow-up computed tomography demonstrated a well-enhanced mass in the right chest wall. Because α-fetoprotein and des-γ-carboxy prothrombin levels were elevated and no other tumors were detected, we diagnosed the mass as an extrahepatic metastasis from the HCC and resected it along with the surrounding ribs. There was no involvement of the bone, pleura, and lung.DISCUSSIONThe tumor was microscopically diagnosed as an intercostal muscle tumor metastasized from HCC, which has not been documented previously. The resection rate of extrahepatic tumors of HCC is low in literature. No other apparent extrahepatic recurrence has been observed for more than 20 months after the surgery.CONCLUSIONWe report the case of HCC patient who underwent surgical resection of an intercostal muscle tumor that had metastasized from HCC. Pathological examination of the tumor revealed the tumor cells in the blood vessels, and we speculate it hematogeneous metastasis. 相似文献

This study reports the first well-documented case of adult T-cell leukemia (ATL) successfully treated with unrelated cord blood transplantation (UCBT). A 49-year-old woman was diagnosed with acute-type of ATL. Chemotherapy induced complete remission, but the human T-cell leukemia virus type 1 (HTLV-1) proviral load was detected in mononuclear cells of her peripheral blood. The patient received UCBT with a conditioning regimen consisting of total body irradiation, cytarabine, and cyclophosphamide. She remains in remission 30 months after UCBT and the HTLV-1 proviral load has fallen to undetectable levels. This result suggests that UCBT should be a therapeutic option for ATL patients who do not have suitable donors and those who urgently require treatment. 相似文献
