Congenital infiltrating lipomatosis

Area of Science:

• Pathology
• Oncology
• Pediatrics

Background:

• Congenital infiltrating lipomatosis (LCI) is a rare, benign soft-tissue neoplasm.
• Characterized by mature adipocytes infiltrating surrounding tissues, nerves, and vessels.
• Often presents with adjacent bone hypertrophy, distinguishing it from other lipomatous tumors.

Observation:

• This article presents a rare case of congenital infiltrating lipomatosis affecting the face of a child.
• The clinical presentation and pathological features of facial LCI are described.
• Diagnostic challenges and therapeutic approaches for this condition are discussed.

Findings:

• LCI is defined by non-encapsulated mature adipocytes with infiltration into muscles and soft tissues.
• Key features include absence of malignancy, lipoblasts, and presence of fibrous elements.
• Observed bone hypertrophy in adjacent structures is a significant characteristic.

Implications:

• Accurate diagnosis of LCI is crucial to differentiate it from malignant liposarcomas.
• Understanding LCI's infiltrative nature guides surgical and therapeutic planning.
• This case contributes to the limited literature on pediatric facial LCI, aiding future management.
