ABSTRACT

BACKGROUND: Intussusception due to lymphoma is a challenging condition for pediatric surgeons. The aim of this study is to report seven cases of this entity and to discuss its management. CASE REPORT: Six boys and one girl, 3-15-years-old, were admitted for intussusception secondary to a lymphoma. All patients underwent laparotomy: biopsy of massive abdominal tumor 6 and 8 weeks following resection of an intussusception (two cases), ileal resection of non-reductible intussusception (one case), right hemicolectomy for tumor of the appendix (one case), tumorectomy of localized ileal tumor (two cases), enlarged mesenteric lymph node biopsy associated with simple reduction of intussusception (one case). All children were successfully treated with protocol chemotherapy with a 15-month to 13-year follow-up. No relapse was observed. CONCLUSION: Surgeons should be aware of operative sights of ileal lymphomas. Diagnosis of lymphoma may be difficult after manual reduction of intussusception. A sample of any abnormality (mesenteric lymph node, peritoneal fluid) should be taken. Intestinal resection allows to reduce the intensity of chemotherapy but must be as limited as possible: ileal resection in cases of complicated intussusception, tumorectomy "in sano" in cases of ileal parietal isolated tumor. Reduction of intussusception alone (with no resection of ileal tumor) seems to be effective if diagnosis of lymphoma is possible from peripheral samples (peritoneal fluid, pleural effusion, mesenteric lymph node, bone marrow biopsy...).

ABSTRACT

INTRODUCTION: Non AIDS-defining cancer would have increased in HIV-patients as suggested by numerous studies. Four cases of adenocarcinoma of unknown primary site with thoracic localization that occurred in HIV-infected patients are described. EXEGESIS: To date, there have been no published data about carcinomas of unknown primary site relating to HIV-infected patients; however, immunodepression could promote them. Carcinomas of unknown primary site account for 0.5 to 10% of all cancer in general population. Primary carcinoma is identified in approximately one third of the cases and often corresponds to lung cancer in case of sus-diaphragmatic metastasis, particularly in case of pleural metastasis. Lung cancer in HIV-infected patients affects mostly young men who smoke and are often intravenous drug addicts. Adenocarcinoma is the most common histological type of cancer. CONCLUSION: Further studies of lung cancer in HIV-infected patients will help evaluate their frequency. In case of increasing frequency, lung cancer should then be included in AIDS-defining cancers.
