Metastatic neuroblastoma masquerading as infantile hemangioma in a 4-month-old child.

INTRODUCTION Diffuse liver lesions in an infant have a differential diagnosis including infantile hemangioma (IH), which is common in the first year of life, and neuroblastoma (NBL) which presents at a median age of 18 months. RESULTS We describe the case of a 4-month-old girl with a known superficial/deep IH who presented with new axillary nodules and hepatosplenomegaly, initially suspected to reflect IH but later determined to be widely metastatic NBL. CONCLUSION Hepatic IH and metastatic NBL can present similarly. Clinicians must maintain a broad differential when evaluating new findings in a patient with previously diagnosed IH.
