[Retroperitoneal cystic mass. Giant exophytic gastric leiomyosarcoma].
Presentation of an unusual case of pre-operatively non-striated retroperitoneal cystic mass confirmed to be a gastric leiomyosarcoma after pathoanatomical study. Considering the rarity of the case, we reviewed the literature as well as the epidemiological, clinical, pathoanatomical and surgical characteristics of gastric leiomyosarcomas which, as in the present case, can appear as retroperitoneal mass.
