Fibrous hamartoma of infancy.

Fibrous hamartoma of infancy is an uncommon fibroproliferative lesion that occurs only in infancy and childhood. The present case is unusual for the presence of two separate lesions, infiltration into the superficial muscle, infiltration and entrapment of nerves, and rapid recurrence after initial surgery. Despite these unusual and suspicious features, follow-up evaluations over the 15 months subsequent to the last resection showed no evidence of recurrence.
