  • Author: Talib Najjar, DMD, MDS, PhD; Chief Editor: Dirk M Elston, MD  more...
 
Updated: Jun 27, 2016
 
 

Diagnostic Considerations

Also consider the following:

  • Brucellosis
  • Botryomycosis
  • Blastomycosis
  • Histoplasmosis
  • Toxoplasmosis
  • Osteomyelitis
  • Multiple myeloma
  • Central giant cell granuloma
  • Fibrous dysplasia
  • Hodgkin lymphoma
  • Burkitt lymphoma
  • Bisphosphonate

Consider actinomycosis infection in the differential diagnosis of any acute, subacute, or chronic cutaneous or soft tissue swelling of the head, face, or neck.
