Pathological Condition of a Newborn Child

This case challenge deals with a pathological condition of a newborn child.

A new born female presented at birth with a paranasal mass which appeared to be hemangiomatous. An ultrasound and aspiration biopsy of the lesion performed at the time of initial exam were not diagnostic. Due to the rapidly increasing size of the mass, the patient was referred for further evaluation to the Department of Oral and Maxillofacial Surgery at a major northwestern children's hospital. The clinical work up included a bone scan, chest and abdominal CT, and soft tissue biopsy.

After you have finished reviewing the available diagnostic information, make the diagnosis.
