Differential Diagnosis for Infection in the Temple Area

• Single most likely diagnosis
  • Cellulitis: This is a common skin infection that can occur in any area of the body, including the temple. It is characterized by redness, swelling, warmth, and tenderness of the skin.
• Other Likely diagnoses
  • Folliculitis: An infection of the hair follicles, which can occur in the temple area, especially if there is a history of shaving or other forms of hair removal.
  • Furuncle (Boil): A localized skin infection, usually starting as a folliculitis, that can occur in the temple area.
  • Impetigo: A highly contagious skin infection that can occur in the temple area, characterized by red sores on the face.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
  • Meningitis: Although less common, infections in the temple area can, in rare cases, spread to the meninges, leading to meningitis, which is a medical emergency.
  • Osteomyelitis: An infection of the bone, which, if occurring in the skull, could be life-threatening and requires prompt diagnosis and treatment.
  • Brain Abscess: A rare but potentially life-threatening complication of an infection in the temple area, where the infection spreads to the brain.
• Rare diagnoses
  • Erysipelas: A type of skin infection that can occur in the temple area, characterized by a bright red, raised rash, and is usually accompanied by fever.
  • Periorbital or Orbital Cellulitis: While not exclusively a temple infection, these conditions can involve the area around the eye, including the temple, and are serious infections that require prompt treatment.
  • Actinomycosis: A rare chronic infection that can affect the skin and tissues of the face, including the temple area, often presenting with abscesses or sinus tracts.
