Abstract
A fibrous hamartoma of infancy presented in a 4-month-old girl as three separate masses on her right hand. Magnetic resonance imaging showed that the lesions had indistinct margins, and were infiltrating to the overlying subcuticular layer; there was pathological contrast enhancement and high signal intensity in the bony medulla. The masses were successfully excised. The radiological and physical appearance of fibrous hamartomas in a child may suggest malignancy, but the lesion is typically benign and treatment by local excision is usually successful.
