Gallbladder carcinoma with choledochoduodenal fistula: a case report with surgical treatment.
A 79 year-old man was admitted to our hospital because of upper abdominal pain and nausea. A mobile tumor was palpable in the right upper abdomen. Abdominal ultrasonography, computed tomography and celiac angiography revealed a gallbladder tumor. Endoscopic retrograde cholangiopancreatography revealed a fistula 1.5 cm oral to the orifice of the papilla of Vater, dilatation of the common bile duct, and a filling defect in the gallbladder. Pancreatoduodenectomy associated with reconstruction using Imanaga's method was performed under a pre-operative diagnosis of gallbladder carcinoma with choledochoduodenal fistula. The gallbladder contained a tumor and two bilirubin stones impacted in the orifice of the duodenal papilla. Histological studies confirmed that the gallbladder tumor was a mucinous adenocarcinoma and had not infiltrated the bile duct. We speculated that choledochoduodenal fistula stimulated the development of cancer due to chronic irritation from pancreatic juice reflux.

Primary omental liposarcoma presenting with torsion: a case report.
An 83 year-old man was admitted because of abdominal pain and distention. A mass measuring 20x10 cm and associated with tenderness and guarding was palpable in the right lower abdomen. Ultrasonography and computed tomography showed a tumor with solid and multiple cystic areas. Celiac angiography showed slight tumor vascularity fed by the right gastroepiploic artery. A malignant tumor of the omentum was suspected. At laparotomy, torsion of the omental pedicle of the tumor was found. Histological examination of the resected tumor revealed characteristics of round-cell liposarcoma, which usually has a poor prognosis. The patient has been alive and well for 2 years. Primary liposarcoma of the omentum has been reported in only seven previous cases. None of these patients presented with torsion, and no report has thus far included a documented survival.

Adult embryonal rhabdomyosarcoma showing marked response to radiotherapy: a case report.
A case of embryonal rhabdomyosarcoma (RMS) arising from adult lower proximal extremity is described. Rhabdomyosarcoma (RMS) is most common among children, but adult embryonal RMS is rare. The patient was a 44-year-old man with a large tumor of the left extremity invading to the pelvis. The histological diagnosis was embryonal RMS. Radiation therapy was delivered a total dose of 50 Gy to the tumor. Although adult RMS, usually pleomorphic type, is considered to be radioresistant, the tumor showed marked response to radiotherapy and local control was achieved easily in this case.

Secondary malignant fibrous histiocytoma following radiation therapy for carcinoma of the uterine cervix: report of two cases.
Two cases of secondary malignant fibrous histiocytoma (MFH) following radiation therapy for uterine cervical cancer are reported. The first case, a 48-year-old woman with a stage IB squamous cell carcinoma of the uterine cervix, underwent a radical hysterectomy with pelvic lymphadenectomy and postoperative radiation therapy. Five years later, she had a poorly differentiated MFH that originated in the right gluteal muscle and lung metastases. The right gluteal tumor and lung metastases were treated with radiation therapy and two courses of cisplatin and etoposide-based chemotherapy. One year after treatment the patient died of multiple pulmonary metastases, although there was no evidence of recurrence in the irradiated field. The second case, a 39-year-old woman with a stage IIB squamous cell carcinoma of the uterine cervix underwent radiation therapy alone. Eighteen years later, well differentiated MFH occurred in the right gluteal muscle with pain on elevation. External radiation therapy was performed because the tumor invaded widely to the right gluteal muscle and pelvic bone. Although the right gluteal pain improved, the tumor showed poor response to radiation. Ten months after treatment, the patient died of multiple pulmonary metastases. These two cases of postirradiation MFH demonstrated different responses to radiation.

Metastasis and invasion of hepatocellular carcinoma mimicking a right adrenal tumor.
A 60-year-old man presented with a large right adrenal mass. Adrenal primary carcinoma invading the liver and retrohepatic inferior vena cava was suspected after preoperative imagings, which included ultrasonography, computed tomography, selective hepatic and adrenal angiography, and magnetic resonance imaging. An en bloc resection of the right kidney, right adrenal gland, posterior hepatic segment, and laterodorsal of the vena cava was performed using an active veno-venous bypass. The defect of the inferior vena cava was closed using a 6 x 10 cm patch of horse pericardium. The cut surface of the resected specimens revealed a smaller necrotic intrahepatic tumor as well as a large extrahepatic tumor which involved the right adrenal gland and extended continuously to the liver, mimicking an adrenal tumor. As the histological features of the two tumors disclosed the same moderately differentiated hepatocellular carcinoma with a trabecular or pseudoglandular pattern, a huge mass of the right adrenal gland with invasion into the right lobe of the liver, which mimicked a primary adrenal tumor, was diagnosed as metastatic hepatocellular carcinoma from a primary hepatic tumor.
