[Intestinal leiomyoma. Case report and discussion of the difficult assessment of grade].

The case of a male patient operated for a leiomyoma of the jejunum is presented. The clinical symptoms, the morphological differential diagnosis and the problems evaluating aggressiveness of this tumour are discussed. We intend to demonstrate that histopathological diagnostic implicate a certain grade of uncertainty too. With the example of leiomyoma we like to show that diagnosis means a tight cooperation of the clinician and his pathologist by collecting clinical and histomorphological data.
