Case Discussion:

Gastric Leiomyoma is the most common benign tumor of the stomach occurring in middle age. Most leiomyomas of stomach are asymptomatic but ulceration may cause pain and signs of gastrointestinal bleeding.

The tumor is normally solitary and frequently develop in the lower half of the stomach but may also be seen in the fundus. They are usually smaller than 3 cm but occasionally may be large at the time of diagnosis. Ulceration of the mucosa overlying the tumor is reported in 50 to 70% of tumors larger than 2 cm in diameter. Most gastric leiomyomas present as endogastric submucosal lesions and may be pedunculated but some, originating from the serosa, develop mainly as exogastric masses.

Case confirmed by endoscopy and pathology.
