1/165. 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 = 1keywords = carcinoma (Clic here for more details about this article) |
2/165. 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 = 5keywords = carcinoma (Clic here for more details about this article) |
3/165. Primary appendiceal adenocarcinoma.Adenocarcinoma of the appendix is rarely encountered and is usually discovered at the pathology examination of the surgical specimen. Adenocarcinoma of the vermiform appendix is a rare neoplasm and constitutes <0.5% of all gastrointestinal neoplasms. There is no symptom of appendiceal cancer, and it is very difficult to diagnose preoperatively. Most female patients are diagnosed as having a gynecologic disease. Second primary synchronous and metachronous neoplasms, especially in the gastrointestinal tract, are found in up to 35% of patients with appendix adenocarcinoma. We report a case of adenocarcinoma in a 56-year-old woman misdiagnosed as having right ovarian carcinoma, and we review the literature.- - - - - - - - - - ranking = 9keywords = carcinoma (Clic here for more details about this article) |
4/165. Adenocarcinoid of the appendix presenting as a disseminated ovarian carcinoma: report of a case.The occurrence of disseminated tumors of the appendix is a rare event. Usually appendix tumors are very small, located on the inside of the appendix, and can be pathologically diagnosed. Adenocarcinoid is an uncommon variant of carcinoid tumors that usually arises in the appendix. This report describes a case of a primary adenocarcinoid of the appendix in a patient who was preoperatively diagnosed to have uterus myomatosus but was intraoperatively found to instead have disseminated ovarian carcinoma. This case demonstrates that the clinical picture can be misleading, and that surgeons therefore always have to wait for the final pathological report before making a final diagnosis.- - - - - - - - - - ranking = 5keywords = carcinoma (Clic here for more details about this article) |
5/165. Mucinous cystadenocarcinoma of the appendix. A rare tumour of the right iliac fossa.A case of mucinous cystadenocarcinoma of the appendix is presented. The clinical feature is a painful syndrome of the right iliac fossa. In our observation, the diagnosis was not allowed by preoperative imaging. appendectomy was initially performed and completed by right hemicolectomy and lymphadenectomy after histological diagnosis of the appendicular malignant tumour was forwarded. The prognosis of this tumour is generally excellent providing early diagnosis and wide enough surgery.- - - - - - - - - - ranking = 5keywords = carcinoma (Clic here for more details about this article) |
6/165. Synchronous mucinous tumors of the ovary and the appendix associated with pseudomyxoma peritonei: CT findings.BACKGROUND: To present the computed tomographic (CT) findings of synchronous mucinous tumors of the ovary and the appendix associated with pseudomyxoma peritonei (PMP). methods: Imaging studies, mainly abdominal CT scans, of three women aged 49-75 years were reviewed. attention was directed to the ovarian masses, peritoneal seeding, and the presence of an appendiceal mucocele. RESULTS: The ovarian tumors and the appendiceal mucocele were clearly demonstrated in two cases, and they were part of the extensive PMP in the third patient. ascites was found in all cases, with internal septation in one. Associated scalloping of the liver margins and hypodense peritoneal implants, with extensive bowel involvement, were seen in another one. Pathologically, there was one case of right ovarian mucinous cystadenoma and villous adenoma of the appendix, one case of right ovarian and appendiceal mucinous cystadenocarcinoma, and one case of bilateral metastatic ovarian implants of appendiceal mucinous cystadenocarcinoma. PMP was found in all. In the case with benign tumors of the ovary and the appendix, the PMP was classified as a benign mucinous spillage. This patient returned 33 months after surgery with PMP, in which epithelial cells were found. CONCLUSIONS: Radiologists should be familiar with the clinical occurrence of synchronous mucinous tumors of the ovary and the appendix associated with PMP and with the typical CT findings of the latter two entities. Alternatively, when the imaging findings suggest ovarian cystic tumor with PMP, the radiologist should be alerted to the probability of a clinically unsuspected appendiceal mucocele and should search for it.- - - - - - - - - - ranking = 2keywords = carcinoma (Clic here for more details about this article) |
7/165. Metastasis from small cell carcinoma of the lung producing acute appendicitis.A case of acute gangrenous appendicitis with perforation caused by metastatic small cell carcinoma of the lung in a 65 year old man is reported. The manifestation of appendicitis occurred more than 4 years after the diagnosis of the bronchogenic carcinoma. With longer survival of patients with disseminated tumors it is probable that new manifestations of those malignancies will be discovered. Acute appendicitis due to metastasis from a distant neoplasm should be considered in the differential diagnosis of right lower abdominal pain in the oncology patient.- - - - - - - - - - ranking = 6keywords = carcinoma (Clic here for more details about this article) |
8/165. Primary appendiceal malignancy mimicking advanced stage ovarian carcinoma: a case series.BACKGROUND: Primary appendiceal malignancy metastatic to the ovaries is a rare condition that may mimic late stage ovarian cancer. This condition is rarely diagnosed preoperatively. CASES: Three patients referred to our institution from 1994 to 1999 for presumed late stage ovarian cancer were found to have primary appendiceal adenocarcinoma, adenocarcinoid, and mucinous cystadenocarcinoma metastatic to the ovaries at laparotomy. We describe the clinical course of these patients and review the relevant literature. CONCLUSION: It is important for the gynecologic oncologist to be aware of the clinicopathological features and surgical management of these malignancies, as the incidence, prognosis, and recommended treatment vary with histological subtype.- - - - - - - - - - ranking = 6keywords = carcinoma (Clic here for more details about this article) |
9/165. Primary adenocarcinoma of the jejunum and coexisting primary adenocarcinoma of the vermiform appendix: a case report.An unusual case of primary adenocarcinoma of the proximal jejunum with coexisting primary adenocarcinoma of the appendix is presented. The symptomatology, diagnosis, surgical management, and prognosis are also presented. To our knowledge, this is the only such case reported in the medical literature of English-speaking countries.- - - - - - - - - - ranking = 10keywords = carcinoma (Clic here for more details about this article) |
10/165. Primary mucinous adenocarcinoma of the appendix: a rare entity in the differential diagnosis of ovarian cancer.We report a 58-year-old female patient with the suspected diagnosis of ovarian cancer. Upon surgical exploration, examination of the appendix revealed the histological diagnosis of primary mucinous adenocarcinoma. This is an unusual consideration in the differential diagnosis of the ovarian cancer. We discuss the diagnosis, classification and treatment of the cancer of the appendix in relation to ovarian cancer.- - - - - - - - - - ranking = 5keywords = carcinoma (Clic here for more details about this article) |
