Non‑syndromic first case of pediatric rhabdomyosarcoma originating from the umbilical left medial ligament: A case report

Abstract

. Rhabdomyosarcoma (RMS) is the most common soft‑tissue sarcoma in children. The present study reports the case of a 2‑year‑old female who presented with abdominal pain and a palpable abdominal mass.
