Malignant tumors of the small intestine are rare. An uncommon finding of leiomyosarcoma located in the fourth part of the duodenum was diagnosed by gastrointestinal contrast studies, CT and angiography. Although malignant lesions of the small bowel are usually diagnosed late and thus are far advanced, curative resection was possible in our case. The location and histology of the tumor permitted a ‘pancreas-preserving segmental duodenectomy’. The operative approach and exposure using the Cattell maneuver is described. It is emphasized that the more extensive pancreatoduodenectomy should be reserved for adenocarcinomas or lesions situated in the proximal part of the duodenum. Thirteen years following the operation, the patient is asymptomatic while CT and gastrointestinal contrast studies reveal no evidence of disease.

“…The symptoms were not characteristic and gastrointestinal symptoms were often poor and delayed because of slow and often exoluminal development of the tumor [4]. It was characterized also by the development of a rich vascular supply from adjacent organs which contrasted with central necrosis.…”

“…This can be explained by two reasons: firstly, there are no specific radiological signs of the tumor and secondly, the distal location in the duodenum makes tumor inaccessible to endoscopy. In addition, even if endoscopic visualization of the tumor is possible, its extra mucosal development makes biopsies often negative [4,7].…”

“…Indeed, on one hand the anatomical complexity of the duodenum imposes different procedures adapted to the location of the tumor, and on the other hand, the rarity of lymph node metastases arouses debate for the need for node dissection. Among the published cases, only 52 cases had a curative surgery [2][3][4][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The review of the various procedures carried out (Table 1) found that the choice of surgical procedure depended much more on the location and the size of the tumor that on the need for node dissection.…”

The duodenal leiomyosarcoma is a rare tumor. Its location in the duodenum makes diagnosis difficult and often delayed. Surgical treatment is not consensual because it must take into account anatomical imperatives which vary depending on the duodenal portion and oncological requirements that are not currently well known especially with regard to the utility of lymphadenectomy. We report 2 cases of leiomyosarcomas located at the angle of Treitz. This location is exceptional and only few cases were reported in the literature. From these 2 new cases and a review of the literature, we analyze the clinical features, diagnosis and treatment of duodenal leiomyosarcoma.

EinleitungGastrointestinale Stromatumoren (GIST) des Duodenums sind seltene Tumoren, aufgrund einer Regression können sie ein zystisches Erscheinungsbild aufweisen [1]. Beim Vorliegen eines zystischen GIST kann dieses anhand der laborchemischen und radiologischen Ergebnisse leicht mit einer Pankreaspseudozyste verwechselt werden [2]. Die Therapie besteht in der radikalen Exstirpation des Tumors, was bei Lokalisation im Duodenum häufig mit ausgedehnten Oberbaucheingriffen einhergeht. Vorgestellt wird eine 71-jährige Patientin mit einem zystischen GIST, der sich klinisch wie eine infizierte Pankreaspseudozyste präsentierte. FallberichtDie Patientin stellte sich bei seit längerer Zeit bestehenden Oberbauchschmerzen mit Fieber bis 39,8 8C vor, die körperliche Untersuchung zeigte einen diffusen Druckschmerz im Oberbauch. Bei der Computertomographie zeigte sich ein monströses, gekammertes zystisches System, das sich von der Cauda pancreatis Abstract Cystic gastrointestinal stromal tumors are rare and can mimick a pancreatic pseudocyst if the stomach or the duodenum are affected. A case of a 58 year old woman is reported. Amylase levels and radiological signs suggested an inflammatory pancreatic pseudocyst. At laparotomy with frozen sections a cystic GIST of the duodenum was diagnosed. Total resection of the tumor with partial resection of the duodenum was performed. The patient remained symptom-free for 24 months follow-up.
