RESUMO
Stromal tumors of the digestive tract are undifferenciated connective tissue tumors, identified as stemming of [pace-maker] cells of Cajal related to the immunohistochimical characterization of the phenotype. Report three new cases. We report three observations of the small bowel stromal tumors reveal by anemia in one case and mass formation in two cases. The aim of this study was to discuss the anatomo clinical, prognosis and management of these tumors
RESUMO
A 45-year old woman presented with a recent paroxysmal hypertension and a flush syndrome. Physical examination revealed an abdominal mass with positive left lumbar contact. The urine metanephrine was high. The CT scan and the Magnetic Resonance imaging [MRI] showed a 10 cm retgroperitoneal tumour apart from the left adrenal gland and driving back the left kidney. The diagnosis of ectopic pheochromocytoma was suspected and the patient was operated. A tumour resection widened to the left adrenal gland and to the kidney was performed The specimen histology showed a well-differentiated liposarcoma associated to an adrenal medullary hyperplasia [AMH] Postoperatively blood pressure was stabilizsed at normal levels. The review of literature show that AMH mimicking a pheochromocytoma is rare and its association with a giant retroperitoneal liposarcoma has never been reported before

The authors make a retrospective study of a series of 140 patients aged 59 years in average, followed up from 1995 to 2002 for adenocarcinoma of the stomach. Surgical resection was performed in 79 percent of the patients with total gastrectomy in 15.4%, partial gastrectomy in 50.6%. Resection was considered as curative in 66%. Lymph node metastases were present in 42, 9 percent of the patients. Margins of resection were involved in 24, 5% of the specimens. The mean survival rate was 26.5 months, 13 months and 5 months after curative resection, palliative resection and without resection
