[Digestive polyposis. Retrospective study of 20 cases]. / Les polyposes digestives. Etude rétrospective d'une série de 20 patients.

BACKGROUND: Three main polyposis syndromes are transmitted as an autosomal dominant disorder: familial adenomatous polyposis (FAP), juvenile polyposis syndrome (JPS) and Peutz-Jeghers syndrome. AIM: Evaluate this management of digestive polyposis. METHODS: Our study included 20 patients which were collected in th departements of pathology surgery and garstroenterology of MT Maarmouri's Hospital, Nabeul city. RESULTS: We reported 15 cases of adenomatous polyposis with 2 family groups. We identified a family group of JPS with 3 members and 2 cases of Peutz-Jeghers syndrome. We found 11 cases of colonic adenocarcinoma out of the 15 patients affected by adenomatous polyposes. FAP is a generalized disorder involving the entire colorectum segment with numerous extra-colonic manifestations. The risk to develop colonic cancer is 100%. JPS is characterised by the development of numerous gastrointestinal juvenile polyps and occurs usually before 20 years old, the progression to cancer is rarely observed. CONCLUSION: Peutz-Jeghers syndrome consists in hamartomatous polyps associated to a characteristic mucosal pigmentation. The patients are usually young adults and have an increased incidence of cancer in extradigestive sites.

[Comparative study of appendical mucocela and pseudomyxoma peritonei. About 25 cases]. / Etude comparative des mucoceles simples et des mucoceles compliques de pseudomyxome. A propos de 25 observations.

AIM: to study the clinicopathological features of the different types of appendical mucocele and to compare them with those of pseudomyxoma peritonei. METHODS: 25 cases of appendical mucocele were operated in the Cap-Bon region in Tunisia during a period of 13 years from 1994 to 2006. RESULTS: 9 retentionnal cysts, 13 mucinous cystadenomas, one serrated adenoma, one hyperplasia of the mucosa and one cystadenocarcinoma were diagnosed. Five cystadenomas as well as the only case of cystadenocarcinoma were associated with pseudomyxoma peritonei. Pseudomyxoma peritonei occurred 20 years later than in simple appendiceal mucocèle and complicated 5 cases of cystadenoma with low grade dysplasia and 1 case of cystadenocarcinoma. CONCLUSION: Preoperative diagnosis of appendical mucocele and pseudomyxoma peritonei should be made on scannographic features in order to assess the adequate surgical management.

[Krukenberg tumor: a clinico-pathological study of 5 cases]. / Tumeur de Krukenberg: etude anatomo-clinique de cinq cas.

BACKGROUND: Krunkenberg tumor is defined as the ovarian metastases of a primary digestive tumor composed of a signet ring cells. AIM: Describe the different characteristics of Krukenberg's tumor to improve diagnostic criteria and the therapeutic approche. METHODS: Five cases of Krukenberg tumor are diagnosed in 5 year period between 2002 and 2005. The clinico-pathological feature are reported. RESULTS: The patient age was ranged from 31 to 58 years. Most ovarian tumors were diagnosed synchronously (3 cases). It was a gastric carcinoma in 3 cases and a colonic carcinoma in 2 patients. Histological diagnosis wass easy. We found in 2 cases a metastasis of colonic mucinous adenocarcinoma with signet ring-cell, in 2 other cases it was a gastric adenocarcinoma with exclusively signet ring cell and in the later case it was a gastric moderately differentiated adenocarcinoma with signet ring cell component. Surgical treatment was given in only 3 patients. CONCLUSION: Prognosis is always unfavourable. The only hope for improved prognosis is to search for ovarian metastasis in all cases of digestive tumor.
