Abstract
Seminoma, a malignant neoplasm originating from germ cells, is a rare diagnosis in pediatric patients and seldom requires surgical intervention. In cases of retroperitoneal lymph node involvement, laparoscopic resection may reduce the invasiveness of the surgical intervention compared to traditional open surgery; however, it raises concerns about the oncological completeness of the procedure. We present a case report of an 11-year-old male patient who was admitted to the hospital for further diagnostic evaluation following abnormal imaging studies prompted by persistent headaches. A computed tomography (CT) scan of the abdomen revealed pathological mass in the left retroperitoneal space. A surgical biopsy of these lesions confirmed the diagnosis of seminoma. The patient was subsequently referred for chemotherapy, and after completing two cycles, a decision was made to proceed with laparoscopic resection of the retroperitoneal lymph nodes. The operation was performed without complications, and the patient continues to receive oncological follow-up. The selection of laparoscopic surgery enabled a reduction in the invasiveness of the surgical procedure while achieving a complete oncological resection of pathological lesions.
