Updated: Mar 08, 2016

Diagnostic Considerations

Congenital self-healing reticulohistiocytosis should also be differentiated from the following other histiocytic disorders known to spontaneously regress in infancy:

Note the following differential diagnoses reported by Zunino-Goutorbe et al[35] :

  • Congenital fibrosarcoma
  • Infantile fibrous hamartoma
  • Infantile myofibroma
  • Ulcerated hemangioma
