Abstract
A 53-year-old male with gastric leiomyosarcoma was reported, in which growth process of the tumour was traced by the review of the findings at the annual gastric mass surveys. The tumour grew from 2.6cm to 5.5cm in diametre during the observation period of 730 days. The doubling time was 631 days. Six cases, including the present one, have been reported, in which the growth process of gastric leiomyosarcoma was observed; in the cases with the long doubling time (631 day and 1090 days), no ulceration was found in the lesion, while in the cases with shorter doubling time (40, 175, 410 and 435 days) the lesion was always ulcerated. The present case had, in addition, an independent leison of Borrmann III type gastric carcinoma. Such a case is extremely rare in the literature.
