[Parapapillary leiomyoma of the second duodenal portion: anatomo-clinical considerations]

The authors describe a rare case of leiomyoma situated in the second duodenal portion near the Vater papillary diagnosed for over eight years. The preoperative investigation isn't able to explain certainly the characteristics and the anatomo-topographic relations of the lesion besides the anatomo-pathologic dates have left a border of uncertainty about the benignity of the lesion. These considerations, as agreed with the greater part of authors, show the necessity of early surgical treatment.
