Metastatic Neuroblastoma Mimicking Multiple Infantile Hemangiomas Diagnosed With Ultrasound.

Neuroblastoma is a malignant tumor derived from the neural crest cells that often involves the adrenal glands and rarely metastasizes to the skin. Here, we present a case of a nine-month-old male infant who presented with multiple noncompressible blue-purple subcutaneous nodules, initially suggestive of atypical deep hemangiomas. The ultrasound revealed a lack of increased vascularity of the masses and an adrenal mass, leading to a biopsy and diagnosis of a neuroblastoma involving the adrenal gland, liver, and skin. We demonstrate that metastatic neuroblastoma can mimic infantile hemangiomas and that noncompressible skin masses warrant further workup with ultrasonography to rule out neuroblastoma.
