11/74. leiomyosarcoma of the gallbladder: a case report.Primary sarcoma of the gallbladder is a rare disease. The tumor occurs more frequently in women. Usually gallstones are present. Symptoms resemble those of cholelithiasis or cholecystitis. The diagnosis is rarely made preoperatively. The patient was a 51-year-old woman with a 2-month history of right upper quadrant pain, nausea, vomiting, and a 10-pound weight loss. Ultrasound showed cholelithiasis and cholecystitis. Laparoscopic cholecystectomy was converted to open as a result of dense tissue in the middle to distal gallbladder. Exploration by a right subcostal incision revealed multiple implants on the surface of the liver and the peritoneum of the upper abdomen. The wall of the gallbladder was very thick and inflamed. cholecystectomy with liver biopsy was performed. pathology revealed poorly differentiated epithelioid leiomyosarcoma of the gallbladder with extension to the liver. The disease followed a very aggressive course and the patient died 3 weeks after the procedure. Recommended treatment is extensive surgical resection that can be followed by radiotherapy or chemotherapy. The tumor follows a very aggressive course, which often lasts a few weeks. prognosis is poor with rare reported 5-year survivals.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
12/74. Xanthogranulomatous cholecystitis mimicking gallbladder cancer: report of a case.A 61-year-old woman was admitted to our hospital with abnormal findings of abdominal computed tomography. Whereas she had neither fever nor abdominal pain, a cholecystitis was suspected. ultrasonography showed a mass in the gallbladder with several stones, and an unclear border between the gallbladder and liver. Computed tomography showed a large-mass in the gallbladder with findings that seemed to indicate hepatic invasion and para-aortic lymph node metastasis. On the basis of these findings, we made a diagnosis of gallbladder cancer associated with hepatic invasion and lymph node metastasis. We treated this gallbladder tumor by hepatic arterial infusion chemotherapy via catheter with cisplatin and 5-fluorouracil. Four weeks after administration of the anti-cancer drugs, the tumorous lesion of the gallbladder could not be detected by abdominal imagings, and the gallbladder wall revealed no irregular findings. During laparotomy, the gallbladder showed signs of chronic cholecystitis, and a cholecystectomy was performed. Findings of the resected specimens showed severe inflammation, fibrosis, and bleeding in the gallbladder wall with infiltration by many foamy cells. Histopathological diagnosis was xanthogranulomatous cholecystitis. We report here a case of xanthogranulomatous cholecystitis mimicking gallbladder cancer and review the literature.- - - - - - - - - - ranking = 10.928654444835keywords = abdominal pain (Clic here for more details about this article) |
13/74. Inflammatory malignant fibrous histiocytoma of the gallbladder: report of a case.We describe herein a case of inflammatory malignant fibrous histiocytoma (IMFH) of the gallbladder that subsequently metastasized to the ascending colon and later to the stomach. A 70-year-old Japanese man with a palpable mass in the right upper quadrant of the abdomen was referred to our hospital for investigation and treatment. Laboratory data showed severe leukocytosis and elevated serum granulocyte colony-stimulating factor (G-CSF) concentrations. A laparotomy was performed, and the tumor was excised en bloc with the gallbladder and part of the liver bed. Histopathologically, the tumor was composed of ordinary malignant fibrous histiocytoma (MFH) components characterized by pleomorphic tumor cells, bizarre giant cells, and conventional spindle cells in a storiform growth pattern, as well as a xanthogranulomatous component, including inflammatory cells, foamy histiocytes, and plasma cells. Immunohistochemical study revealed that the pleomorphic tumor cells and bizarre giant cells were positive for antibodies against alpha1-antitrypsin and alpha1-antichymotrypsin. The final pathologic diagnosis was IMFH. The tumor cells were diffusely positive for anti-G-CSF monoclonal antibody, and the inflammatory reaction subsided immediately after tumor resection, strongly suggesting that the primary tumor cells produced G-CSF. This patient is still alive with no signs of recurrence more than 3 years after his primary operation, which to our knowledge is the longest survival period ever reported. Therefore, visceral IMFH is manageable in some cases by resecting the primary and isolated metastatic lesions.- - - - - - - - - - ranking = 0.5keywords = upper (Clic here for more details about this article) |
14/74. Malignant stromal tumor of the gallbladder with interstitial cells of cajal phenotype.Malignant mesenchymal tumors of the gallbladder are exceedingly rare. We report a malignant stromal tumor of the gallbladder with a phenotype of interstitial cells of cajal. To our knowledge, only the benign counterpart of this tumor has been described previously. A 34-year-old woman presented with right upper quadrant abdominal pain. At the time of cholecystectomy, the gallbladder was noted to have a thickened wall and a polypoid mass arising in the neck of the gallbladder. Histologic sections showed a cellular proliferation of spindle neoplastic cells that were arranged in short fascicles. Numerous mitotic figures and foci of necrosis were noted. The neoplastic cells expressed CD117 (c-Kit protein) and vimentin. They were negative for smooth muscle actin, desmin, myoglobin, cytokeratin, S100 protein, and CD34. Our case demonstrates that a malignant stromal tumor that is histologically and immunohistochemically identical to gastrointestinal stromal tumor can occur in the gallbladder, and that the expression of CD117 may be of therapeutic importance.- - - - - - - - - - ranking = 11.428654444835keywords = abdominal pain, upper (Clic here for more details about this article) |
15/74. Double cancer of gallbladder and bile duct associated with anomalous junction of the pancreaticobiliary ductal system.We report a case of double cancer of the gallbladder and the common bile duct associated with anomalous junction of the pancreaticobiliary ductal system, and review the literature of similar case reports. A 66-year-old woman was admitted to an associated hospital complaining of upper abdominal pain, and was diagnosed as having pancreatitis. Abdominal imaging revealed an irregularly protruding mass at the body of the gallbladder and an intraluminal protrusion at the lower third of the common bile duct. Endoscopic retrograde cholangiopancreatography also revealed anomalous junction of the pancreaticobiliary ductal system with congenital biliary dilatation of 14 mm in the largest diameter. She underwent surgical resection of the gallbladder, the extrahepatic bile duct and the gallbladder bed of the liver with a dissection of the regional lymph nodes for double cancer of the gallbladder and the bile duct associated with anomalous junction of the pancreaticobiliary ductal system. She is still alive 33 months after surgery without any signs of recurrence. There were 12 patients (including our case) reported in the literature who had double cancer of the gallbladder and the extrahepatic bile duct associated with anomalous junction of the pancreaticobiliary ductal system. Only 33% of these 12 patients had jaundice. Tumors of the 12 patients were commonly early-stage cancer both in the gallbladder (36%) and in the extrahepatic bile duct (73%). Therefore, we concluded that precise preoperative imaging of the total biliary tract should be required in order to detect early-stage cancer in patients with anomalous junction of the pancreaticobiliary ductal system before planning surgical procedures, and consideration should be given to the possibility of multiple occurrences of biliary tract cancers.- - - - - - - - - - ranking = 355.03653083184keywords = upper abdominal pain, abdominal pain, upper (Clic here for more details about this article) |
16/74. Gingival metastasis from gallbladder cancer.gallbladder cancer is generally diagnosed at an advanced stage. The liver is the most commonly invaded organ by direct extension and/or metastasis, followed by regional lymph nodes. Oral soft tissue metastasis is extremely unusual. This report describes the case of a 62-year-old woman diagnosed with advanced metastatic gallbladder cancer, who initially presented with abdominal pain. diagnosis of gallbladder cancer was made about 3 months after her symptoms developed, when a laparoscopic cholecystectomy was performed because of the suspicion of gallstones. liver metastasis was also discovered during surgery. A postoperative investigation revealed additional lung and bone metastases. A visible left gingival tumor was found on physical examination and was confirmed as gallbladder cancer metastasis by compatible histopathology 1 month after surgery. The patient responded poorly to chemotherapy and unfortunately died 5 months after the diagnosis. The clinical presentation of gallbladder cancer was relatively typical, apart from the unusual gingival metastasis. The medical literature contains quite a few examples of metastatic lesions located strictly in the oral soft tissue, however no case of gallbladder cancer metastasizing to the oral soft tissue has been previously reported.- - - - - - - - - - ranking = 10.928654444835keywords = abdominal pain (Clic here for more details about this article) |
17/74. Covered expandable metallic stent placement for hemostasis of colonic bleeding caused by invasion of gallbladder carcinoma.A 72-year-old Japanese man was admitted to our hospital complaining of right upper-quadrant abdominal pain, blood in his stool, and symptoms of anemia. On physical examination a hard mass, about 6 cm in diameter, was palpable in the right upper quadrant of the abdomen. Computed tomography revealed a gallbladder carcinoma which had invaded the transverse colon, with liver metastasis. We diagnosed gallbladder carcinoma, stage IVB. colonoscopy was performed for persistent blood in the stools. This revealed an elevated lesion which appeared to be an invasion of gallbladder carcinoma, with diffuse bleeding from the right-side of the transverse colon. It proved difficult to stop this bleeding by ordinary therapeutic endoscopy. In order to achieve hemostasis we therefore inserted a covered Ultraflex metallic stent to compress the tumor. After stent placement, blood was no longer seen in the patient's stools, he became able to eat soft food and was discharged. This treatment was uninvasive and effective. Covered stent placement appears to be a new and useful method in the management of bleeding from malignant gastrointestinal tumors.- - - - - - - - - - ranking = 11.928654444835keywords = abdominal pain, upper (Clic here for more details about this article) |
18/74. Coexistent gallbladder carcinoma in mirizzi syndrome.A 52-year-old woman presented with right upper quadrant pain and obstructive jaundice. Computed tomographic scan showed mirizzi syndrome type 1 and a thickened and calcified gallbladder wall, raising the possibility of coexistent gallbladder carcinoma that was later confirmed on histology post-cholecystectomy.- - - - - - - - - - ranking = 0.5keywords = upper (Clic here for more details about this article) |
19/74. Symptomatic adenomyomatosis of the gallbladder--report of a case.Adenomyomatosis of the gallbladder is a benign and degenerative condition of the gallbladder, characterized by proliferation of the mucosa of the gallbladder wall, forming invaginations and diverticula, penetrating a thickened muscular layer: the so-called Rokitansky-Aschoff sinuses (RAS). Most of the patients with adenomyomatosis remain asymptomatic. Hence adenomyomatosis is usually an incidental finding, either on ultrasonography performed for the detection of stones or by histologic examination of surgical gallbladder specimens. Only occasionally does adenomyomatosis not associated with cholelithiasis cause right upper quadrant pain. We report a case of symptomatic adenomyomatosis of the gallbladder. Clinical findings, etiology, diagnosis and therapy are discussed.- - - - - - - - - - ranking = 0.5keywords = upper (Clic here for more details about this article) |
20/74. Atypical courses of serum tumor markers--4 case reports.We report on 4 cancer patients with transient unspecific elevations of the serum tumor markers CA 19-9, CEA, CA 125 and CA 72-4, respectively. In one patient cholangitis due to biliary obstruction induced a significant transient increase of CA 19-9, in another patient HUS, probably as a severe complication after mitomycin-C Gemcitabine therapy resulted in a significant increase of serum CA 125. One patient demonstrated an extensively elevated and inexplicable serum CA 19-9 concentration (9450 u/ml) during a period of abdominal pain with continuous decrease and finally normalization within the following 5 years. Also inexplicable is an unexpected remittent increase of serum CA 72-4 in the course of chemotherapy after gastrectomy for gastric carcinoma. The presented data underline the necessity of interpreting serum courses of tumor markers only in the light of all available clinical data, imaging data and other laboratory tests in order to avoid misinterpretations.- - - - - - - - - - ranking = 10.928654444835keywords = abdominal pain (Clic here for more details about this article) |
