Gastric leiomyoma is the most common benign tumour of the stomach occurring in middle age. Most leiomyomas of stomach are asymptomatic but ulceration may cause pain and signs of gastrointestinal bleeding.
The tumour is normally characterised as:
- solitary mass
- in the lower half of the stomach but may also be seen in the fundus
- smaller than 3 cm, but occasionally may be large at the time of diagnosis
- with ulceration of the mucosa overlying the tumour in 50 to 70%
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.
