Rare presentation of benign retroperitoneal benign and malignant EGIST in young female patients with gynecologycal complaints

Introduction.Gastrointestinal stromal tumors (GISTs) originate from the gastrointestinal (GI) tract, but data from the last 30 years show that there are formations with pathologically and immunohistochemically similar GIST lesions, but located outside the gastrointestinal tract and have been referred to as extra-GISTs (eGIST).There is a rare incidence of eGIST, and information regarding the search for survival is scarce.Information such as tumor markers, tumor size, immunohistochemistry are important to help understand these rare pathologies.Case presentation.We present 2 cases that appeared in the Obstetrics and Gynecology Clinic in 2022, one with a result considered benign with a retroperitoneal tumor and one malignant, both patients benefiting from surgical intervention.The surgical team consisted in both cases of both gynecologists and general surgeons.Conclusions.The publication of these results in the literature will be important for the assessment of the conduct, the treatment.
