title: [Malignant gastrointestinal stromal tumor arising in a duodenal diverticulum].
abstract: Malignant gastrointestinal stromal tumor arising in a duodenal diverticulum. The authors describe the case of a 74-year-old male patient who was operated on for a GIST found in a large duodenal diverticulum, co-using gastrointestinal bleeding. This diverticulum--including the tumor--was removed by resection the distal part of the stomach and proximal third of duodenum. The histology revealed malignant gastrointestinal stromal tumor (GIST). 6 months after the operation he remained tumor free according to the control examinations. On the basis of new pathologic classification we summarise the signs, the diagnostic and therapeutic possibilities and the histologic characteristics of gastrointestinal stromal tumors.
