Manifestation of Abdominal Lymphoma as Retroperitoneal Fibrosis in a Child: A Case Report

[摘要] Non-Hodgkin’s lymphoma includes 60% of lymphoma cases in children and adolescents. Burkitt’s lymphoma and diffuse large B-cell lymphoma (DLBCL) patients usually have intra-abdominal tumors. Non-Hodgkin’s lymphoma (NHL) may present as retroperitoneal fibrosis (RF). In the present paper, a 7-year-old boy was reported who was hospitalized in our hospital because of stomachache, vomiting, and weight loss. In the patient’s history, it was found that 3 weeks ago, the patient complained of flank pain and suspected kidney stones, but urethroscopy revealed that he did not have kidney stones. After admission to our hospital, upon the examination of the abdomen, we noticed a palpable mass in the patient’s epigastric region. Diagnostic laparoscopy was performed, and a large number of hard lesions similar to fibrosis were detected in the mesogastric region, the first part of the small intestine, the head of the pancreas, and the liver. Finally, DLBCL was diagnosed in this patient.
