[Bleeding gastric leiomyoma: diagnostic error solving an emergency case].

Although rare, benign gastric tumours are frequently encountered in the recent years thanks to the greater accuracy of diagnostic investigations. The Authors report their experience in a case of bleeding gastric leiomyoma which caused preoperative diagnostic problems due to the extraluminal development of the tumor and to diagnostic investigation errors. An easy diagnosis of this type of tumor is not therefore a rule, but, as in the case reported, may be rather insidious especially in small leiomyomas with an extra or intraparietal development and aspecific symptomatology masquereding other more frequent pathologies.
