title: Fibrous hamartoma of infancy. Case report.
abstract: BACKGROUND
  Fibrous hamartoma of infancy (FHI) is an infrequent benign proliferation of the soft tissues. Ninety one percent of cases occur during the first year of life. FHI is characterized as a subcutaneous lesion with characteristic morphology with a triphasic organoid growth pattern.
  
  
  METHODS
  We present the case of a 6-month-old male infant with a tumor in the medial plantar region of the left foot, which was completely withered. Histopathological study reported a fibrous hamartoma of infancy.
  
  
  CONCLUSIONS
  Fibrous hamartoma of infancy most frequently affects males. It may be localized at any anatomic site, although 5-10% of cases affect the lower limbs. Few cases are reported in the foot. This is a lesion with a characteristic morphological pattern; however, in small biopsies, its differential diagnosis is important with other fibroadipose lesions for appropriate treatment. Ample surgical resection with lesion-free borders confers a good prognosis for these patients.
