1/104. Primary malignant fibrous histiocytoma of the ascending colon: report of a case.We report herein an unusual case of primary malignant fibrous histiocytoma (MFH) of the ascending colon. A 47-year-old man was admitted to our hospital for further investigations following the discovery of a mass in the right lower quadrant of the abdomen during a medical checkup. Abdominal ultrasonography (US) and computed tomography (CT) demonstrated a mass extending to the right lateral side from the ascending colon. At laparotomy, a tumor was found originating in the ascending colon and infiltrating the right lateral peritoneum. A right hemicolectomy and partial peritoneal dissection were performed followed by an ileotransverse colostomy reconstruction. The resected specimen contained a tumor measuring 7 x 5 x 4 cm, the cut surface of which was yellowish white, and the mucosa of the colon was intact. Based on histological and immunohistochemical inspection, the tumor was diagnosed as MFH of the ascending colon. We reviewed the total 18 known cases of colorectal MFH documented in the literature including our case. After surgery, 4 of 17 patients died of local recurrence, all within 42 months, indicating that early and complete excision of tumor is essential to achieve cure.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
2/104. A case of primary leiomyosarcoma of the lesser omentum.leiomyosarcoma is a rare tumor that originates in the smooth muscle, usually in the gastrointestinal tract, the retroperitoneum and the genitourinary tract. The omentum has been rarely reported as a primary site of occurrence with leiomyosarcoma. A 72 year-old woman, with palpable mass on the left upper quadrant of abdomen and weight loss, was admitted to St. Paul's Hospital. Abdominal CT scan showed a 12 x 8 x 8 cm-sized cystic mass in the left upper quadrant of the abdomen. Endoscopic ultrasonography showed a large cystic mass between the stomach and the liver, which was 1.6 cm length in wall thickness. laparotomy and resection of the mass was performed. A 12 x 8 x 8 cm-sized mass, originated from the lesser omentum, was discovered near the lesser curvature of the stomach. Microscopic examination revealed spindle-shaped cells with 7-8 mitoses per high power field. She was diagnosed as primary leiomyosarcoma originated from the lesser omentum.- - - - - - - - - - ranking = 2keywords = abdomen (Clic here for more details about this article) |
3/104. pseudomyxoma peritonei in the pleural cavity: report of a case.PURPOSE: pseudomyxoma peritonei is a rare disease characterized by mucinous ascites and associated with ruptured mucocele, cystadenoma, and low-grade carcinoma arising from the appendix, ovaries, or colon. Metastases and extraperitoneal involvement are extremely rare events. METHOD: This is a case report of a patient with pseudomyxoma peritonei with pleural involvement. RESULTS: A 38-year-old male patient with a pseudomyxoma peritonei from appendiceal origin underwent an extensive cytoreduction procedure. During the operation pleural involvement was noted. This was later confirmed by thoracoscopy. An expectant policy was followed until the patient became symptomatic with progressive disease in the abdomen and both pleural cavities. With systemic chemotherapy (5-fluorouracil and leucovorin), a good clinical response was obtained, and the patient was alive with stable disease 2.5 years after the first diagnosis. CONCLUSIONS: Involvement of the pleural cavity by pseudomyxoma peritonei is rare and carries an unfavorable prognosis. Whenever possible, the same guidelines as for intra-abdominal disease should be followed: extensive cytoreductive procedures with local and/or systemic chemotherapy. In our patient we hope to achieve a prolonged palliation with systemic chemotherapy.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |

5/104. Successful surgical treatment for implanted intraperitoneal metastases of ruptured small hepatocellular carcinoma: report of a case.We report herein the case of a 53-year-old man with disseminated intraperitoneal metastases caused by the rupture of small hepatocellular carcinoma (HCC). He was admitted to our hospital in shock after suffering a trauma injury to the upper abdomen. ultrasonography revealed a massive hemoperitoneum. At surgery, 4000 ml of blood was drained from the abdominal cavity and a ruptured tumor, 2 cm in diameter, was found in the right lobe of the liver. The tumor was resected with an adequate surgical margin and subsequent microscopic examination confirmed a diagnosis of moderately differentiated HCC without associated liver cirrhosis. The patient was readmitted 14 months later following the development of right lower quadrant pain. ultrasonography and computed tomography revealed extrahepatic abdominal tumors, and abdominal angiography demonstrated four intraperitoneal tumors. At surgery, four implanted metastases adhered to the greater omentum were found and resected. No other tumors were detected. Microscopically, all four tumors were confirmed as moderately differentiated hepatocellular carcinoma. Ruptured HCC may lead to implanted intraperitoneal metastasis, but rupture of small HCC is very rare. While hepatic resection is the treatment of choice for ruptured HCC, according to our review of the literature, only a few patients have survived long-term after resection of implanted metastasis.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
6/104. Laparoscopic management of pseudomyxoma peritonei secondary to adenocarcinoma of the appendix.pseudomyxoma peritonei is a rare disease in which the abdominal cavity fills with thick mucoid material secondary to either benign or malignant conditions. We discuss a case where pseudomyxoma peritonei secondary to adenocarcinoma of the appendix was diagnosed and managed laparoscopically. The laparoscopic approach allows thorough exploration of the abdomen, as well as irrigation and aspiration of the thick mucinous material using a 10-mm suction cannula and the instillation of mucolytic agents such as 5% dextrose solution. appendectomy or right hemicolectomy can be performed with minimal disturbance of the anterior abdominal wall, thus minimizing future adhesions as well as possible tumor-cell implantation. Intraperitoneal catheters for chemotherapy can be placed easily through the port sites. These measures offer an alternative to radical peritoneal dissection and can be accomplished during the initial laparoscopic exploration.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
7/104. 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.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
8/104. Mucinous epithelial cysts of the spleen associated with pseudomyxoma peritonei.AIMS: We report two rare cases of neoplastic pseudomyxoma peritonei associated with splenic mucinous epithelial cysts and review previously reported cases of splenic mucinous lesions in order to investigate the extent and implications of such an association. methods AND RESULTS: The majority of mucinous lesions of the spleen appear to be associated with pseudomyxoma peritonei. The clinicopathological profile of these cases conforms to that of neoplastic pseudomyxoma peritonei, showing a similar age of onset, outcome and histological features. Most of the cases were associated with a confirmed or suspected appendiceal primary. The immunophenotype (cytokeratin 7 negative; cytokeratin 20 and CEA positive) of the lesions of both our cases, including those in the ovary, was suggestive of a gastrointestinal origin. CONCLUSIONS: splenomegaly due to cystic intrasplenic mucinous epithelial lesions may occasionally be the presenting feature of pseudomyxoma peritonei or herald tumour recurrence. Mucinous epithelial cysts of the spleen may also precede the development of pseudomyxoma peritonei. All cases of pseudomyxoma peritonei should be investigated for splenic involvement and, conversely, a primary mucinous neoplasm sought elsewhere in the abdomen in all cases of splenic mucinous cysts.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
9/104. Multifocal omental mesenteric inflammatory pseudotumor (plasma cell granuloma).Inflammatory pseudotumor (IP) is an uncommon benign tumor during childhood. The most common location is lung, and sporadic cases of IP with extrapulmonary involvement such as liver and abdomen are reported. However, the IP among the reported cases have appeared as solitary masses. A multifocal IP in a 14-year-old girl presumed to result following an entamoeba histolytica infestation is reported.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
