Nasal Fibrolipomatous Hamartoma, an Idiosyncratic Connective Tissue Malformation in an Infant

ABSTRACT

We describe a congenital mass in the nasopharynx of an infant presenting with dyspnea and feeding difficulties. Magnetic resonance imaging demonstrated 2 separate polypoid nasal cavity masses that were endoscopically resected. Histologically, both lesions were composed of mature adipose tissue with broad fibrous bands and several foci of brown fat. PLAG-1 and HMGA-2 were negative by immunostains. The best diagnosis was a fibrolipomatous hamartoma.
