Benign tumors of stomach and duodenum are not common and constitute only 5–10% of all stomach tumors, and 10–20% of all duodenal tumors. Though these lesions are benign, some of them can become malignant.
Therefore, early diagnosis, correct treatment and proper longterm follow-up are important. Over the recent years, the incidence of these lesions is rising due to a higher level of suspicion exhibited by clinicians, and the availability and wide application of diagnostic tools, such as gastrointestinal endoscopy.
