[A case of leiomyoblastoma of the stomach. Clinical and anatomopathologic considerations]

Gastric leiomyoblastoma or Martin's myoid tumour or Stout's smooth muscle cell bizarre tumour is a rare benign mesenchymal neoplasia that may become malignant. A personal clinical case is reported and the most important anatomopathological and clinical aspects are reviewed, stress being laid on the importance of identifying the macroscopic and histological features that can point with certainty to malignity and so influence the choice of surgery. This, depending on the situation, may tumorectomy, gastric resection or gastrectomy with exeresis of any metastases.
