Fibrous hamartoma of infancy (FHI) is an uncommon, benign lesion with a distinctive histologic appearance, usually occurring as a small, rapidly growing soft tissue swelling developing in the first two years of life. Apart from one publication, there appear to be few descriptions of the fine needle aspiration biopsy (FNAB) features of this lesion. Detailed information on the clinical and FNAB findings in a patient with FHI is presented.
