title: [Gastric leiomyoblastoma].
abstract: Three cases of gastric leiomyoblastomas are presented (according to Stout's denomination) or epithelioid leiomyomas (according to Appelman). The subject is actualized and the low malignant potential of these tumors is pointed out. Leiomyoblastomas have to be classified among the leiomyomas (absolutely benign) and the leiomyosarcomas (malign). The lack of reliable criteria to determine the future of the patient is established, being the evolutive control the only way to make that clear. The mitotic counts--more than 5 for each 50 high-power dry objective field--is the most important isolated criterion to predict the probable malignancy of the lesion.
