Summary
A case of leiomyoblastoma of the duodenum is presented with light and electron microscopic observations. This type of tumor is exceedingly rare in this location, and apparently was responsible for a series of bleeding episodes in the patient. Though the origin of the tumor may be in question from the light microscopic studies, the findings on the ultrastructural level support an origin from smooth muscle.
