Infantile Abdominal and Pelvic Lipoblastomas: A Case Series

Abstract

Lipoblastomas are rare benign mesenchymal tumors that arise from embryonal fat cells.They are usually discovered in infants and children under 3 years of age, and mostly occur in the trunk (from 10 to 60%, depending on the study) and extremities (from 40 to 45%), while head and neck localizations are rare, with only five cases described to date.We report on three cases of lipoblastomas in infants younger than 4 years, with unusual localizations: one intra-abdominal, discovered during a laparotomy for an intussusception; one pelvic, misdiagnosed as an ovarian mass; and one gluteal with a pelvic extension.All children underwent magnetic resonance imaging as preoperative workup. All tumors were completely resected with free surgical margins and ultrasonographic follow-up was uneventful for all patients.

Pelvic Lipoblastoma with Extension into Ischiorectal Fossa and Abdominal Lipoblastoma - Complete Excision by Laparoscopy in Children - A Report of Two Cases

“…More than 90% of lipoblastoma occurs in those below 3 years of age. [ 7 ] It occurs mostly in trunk (10%–60%) and extremities (40%–45%);[ 7 ] however, abdomen and pelvic lipoblastomas are rare. Abdominal tumors are usually detected incidentally, while pelvic tumors can present with mass effects such as constipation or urinary disturbance.…”
