1/414. Palliative sclerosis of intra-abdominal cystic ovarian or peritoneal carcinoma.Three patients with platinum- and paclitaxel-resistant predominantly cystic intra-abdominal recurrences of ovarian or peritoneal carcinoma were treated with CT-guided percutaneous catheter drainage and subsequent sclerosis. This relieved colonic or ureteral obstruction and provided significant relief from symptoms. In one case repeated sclerosis was performed. sclerosis of cystic recurrences may provide additional palliation.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/414. Pseudomyxoma retroperitonei with spontaneous skin fistula.We describe the imaging features in a patient with pseudomyxoma retroperitonei arising from a mucinous carcinoma of the appendix with spontaneous development of a skin fistula. The thick wall and septa characteristic of pseudomyxoma were best demonstrated on gadolinium-enhanced magnetic resonance imaging. This patient illustrates (a) the potential of pseudomyxoma to cause skin fistula and (b) the possibility that this intraabdominal process can first present as a dermatologic complication.- - - - - - - - - - ranking = 0.2keywords = carcinoma (Clic here for more details about this article) |
3/414. dermatomyositis and peritoneal papillary serous carcinoma.We describe an unusual case of peritoneal papillary serous carcinoma (PPSC) arising in a female patient with dermatomyositis (DM). Despite periodic extensive searches for an underlying malignancy, no malignancy had been detected in this patient during the first 2.5 years after the diagnosis of DM. It was only when the patient presented with pleural effusion and ascites that the underlying intra-abdominal malignancy was detected by laparoscopy. Treatment with four cycles of pre-operative chemotherapy (taxol and cisplatin) resulted in tumor regression with amelioration in the muscular manifestation of the DM, but without parallelic amelioration in the skin manifestations of the DM. Explorative laparotomy confirmed the presence of papillary serous carcinoma in the omentum, surface of the left ovary and the retroperitoneal lymph nodes, and established the diagnosis of PPSC. Following two cycles of postoperative chemotherapy, the patient is alive with no evidence of internal malignancy. However, although muscle strength and enzymes have remained normal, no effect on the skin manifestation of DM has been observed. This case illustrates that, alongside the more frequently occurring ovarian carcinoma, PPSC should also be considered in the differential diagnosis of the underlying malignancy that may occur in the female patient with DM.- - - - - - - - - - ranking = 1.4keywords = carcinoma (Clic here for more details about this article) |
4/414. 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 = 0.2keywords = carcinoma (Clic here for more details about this article) |

6/414. Peritoneal mucinous carcinomatosis after laparoscopic-assisted anterior resection for early rectal cancer: report of a case.Minimally invasive colon surgery has been shown to be both technically feasible and a safe alternative to laparotomy. Its efficacy for the curative resection of colorectal cancer, however, remains controversial. Of major concern are the increasing reports of port-site recurrence after use of laparoscopic techniques in malignant disease. In this article a heretofore unreported complication of peritoneal mucinous carcinomatosis after laparoscopic-assisted anterior resection for early stage rectal cancer is presented. Isolated peritoneal recurrence is rare after curative resection of Stage I rectal cancer. The effect of pneumoperitoneum on tumor dissemination is discussed.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
7/414. Urinary undiversion for pelvic actinomycosis: a long-term follow up.BACKGROUND: A 43-year-old woman who had been using intrauterine contraceptive devices for the past 10 years underwent an emergency operation for bowel and urinary obstruction. methods/RESULTS: Frozen section analysis showed undifferentiated adenocarcinoma. Incomplete tumorectomy, ileal resection, partial cystectomy, colostomy and bilateral ureterocutaneostomy were palliatively performed. Postoperatively, periodic acid-Schiff and Grocott-Gomori methenamine tests revealed actinomyces and the final diagnosis was pelvic actinomycosis. Treatment with penicillin g administered intravenously relieved her symptoms and the lesion was dramatically improved. The patient underwent colostomy closure and urinary undiversion. CONCLUSIONS: Five years after urinary undiversion, the patient's renal function has been maintained and she can void without incontinence and dysuria.- - - - - - - - - - ranking = 0.2keywords = carcinoma (Clic here for more details about this article) |
8/414. Extraosseous metastases of hepatocellular carcinoma detection and therapeutic assessment with Tc-99m PMT SPECT.Owing to recent advances in imaging technology and radiologic intervention, survival rates in patients with hepatocellular carcinoma have improved markedly. However, such prolonged survival has resulted in an increase in extrahepatic metastases. Tc-99m (Sn)-N-pyridoxyl-5-methyltryptophan (Tc-99m PMT), developed for hepatobiliary scintigraphy, has been used to visualize extrahepatic metastases, with most related reports limited to osseous metastases. The authors report two cases of hepatocellular cancer presenting as a hypopharyngeal metastasis and intraperitoneal dissemination along the tract of a fine-needle biopsy. Lesions undetectable on planar imaging could be visualized by Tc-99m PMT SPECT.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
9/414. Conservative surgery in a young patient with peritoneal psammocarcinoma.Psammocarcinoma is a rare epithelial neoplasm of the ovary and peritoneum. The reported management of patients with this tumor includes radical surgery and chemotherapy. We report the case of a young woman with metastatic psammocarcinoma treated with conservative surgery who is alive 6.5 years following positive second-look laparotomy.- - - - - - - - - - ranking = 1.2keywords = carcinoma (Clic here for more details about this article) |
10/414. Primary peritoneal psammocarcinoma: A case presenting with an upper abdominal mass and elevated CA-125.Primary peritoneal serous adenocarcinoma with predominating psammoma bodies, psammocarcinoma, is a very rare tumor with only seven cases documented in the English literature. Pathological classification of this entity was established in 1990 and clinical behavior of this tumor is uncertain. Based on limited data these tumors appear to behave similarly to low malignant potential tumors of the ovary. This case describes a 59-year-old woman who underwent exploratory laparotomy for a large upper abdominal cystic mass. Findings included a large tumor mass involving the gastrocolic omentum and dense small bowel adhesions. The patient had normal ovaries and was debulked to no macroscopic disease. Final pathologic diagnosis confirmed a stage IIIC primary peritoneal psammocarcinoma. The patient has received no adjunctive therapy and is without evidence of disease 2 years after surgery. Primary peritoneal psammocarcinoma is a neoplasm which can mimic serous adenocarcinoma of the ovary. In contrast, primary peritoneal psammocarcinoma appears to behave in an indolent fashion. Primary surgical debulking should be attempted, while the utility of postoperative chemotherapy remains unknown.- - - - - - - - - - ranking = 2keywords = carcinoma (Clic here for more details about this article) |
