[Nonchromaffin neurogenic tumors of the intestinal tract. A report of 2 cases and their relation to von Recklinghausen's neurofibromatosis]. / Tumores neurogénicos no cromafines del tracto intestinal. Aportación de dos casos y estudio de su relación con la neurofibromatosis de von Recklinghausen.

Two patients with neurogenic gastrointestinal tumors are reported. One of them was a gangliocytic paraganglioma of the duodenum. The second one, a jejunal tumors in a patient with Von Recklinghausen's disease (ganglioneuroma). The neural crest origin of these tumours is discussed.

[Adenocarcinoma of the kidney pelvis]. / Adenocarcinoma de pelvis renal.

We present a case of primitive renal pelvis and calix adenocarcinoma. The clinical evaluation was carried out by means of UIV, echography and TC. Although the tumoral type diagnosis is histologic, the clinical manifestations of chronic renal infection-inflammation, whether associated with obstruction and/or lithiasis or not, are suggestive of this possibility.

[Primary tumors of the small intestine]. / Tumores primarios del intestino delgado.

We made a retrospective analysis of 43 cases of primary tumor of the small intestine, 28 benign and 15 malignant, diagnosed and treated in our hospital over a period of 18 years. A preoperative diagnosis was reached in 13 cases (30%), while in 37.2% the tumor was a casual finding during operation by other methods. The remaining 32.5% debuted as acute abdomen and were an emergency surgical indication. Simple tumoral resection was practiced in 19 cases (44.1%) of benign tumor, intestinal resection with end-to-end anastomosis in 22 cases (51%) and only biopsy in two cases (4.6%). Coadjuvant chemotherapy was given to five patients (11.5%) and radiotherapy to one (2.3%). The one-year survival for malignant tumors was 73%, and only 18% (2 cases) survived more than 5 years after the operation).
