Neoplasms of the Pelvic Cavity in Pediatrics. Features of Differential Diagnosis

The frequency of detection of stromal gastrointestinal tumors in children and adolescents is about 0.4% of the total number of diagnosed GISTs. These tumors can occur throughout the gastrointestinal tract. During the instrumental research, misinterpretation of tumor origin is possible. For this reason, the consistent use of a variety of non-invasive diagnostic methods is extremely important in the preoperative period. We present a case report of a rare GIST detection in pediatrics, which at the stage of noninvasive diagnostic studies was determined as a pelvic tumor. It was possible to accurately determine its origin only after diagnostic laparoscopy. We also provide a description of instrumental and laboratory research methods for the differential diagnosis of the abdominal and pelvic cavities neoplasms
