      2. Yellow, purulent discharge
    2. Thoracic
    3. Abdominal
  4. Diagnosis
    1. Histopathology
    2. Cultures
4. Parasites
Non-infectious
1. Idiopathic OFG
  1. = restricted to oral cavity with no known granulomatous disease
2. Crohn's disease
  1. Clinical features
    1. Oral
      1. Angular cheilitis
      2. Cobblestone mucosa
      3. Aphthous-like oral ulcers

    1. Fissured tongue
    2. Facial paralysis
    3. Facial swelling (lips)
      1. Most common = lower lip
    4. Rare for all to occur at the same time
  2. Management
    1. Elimination of diet
    2. Topical Steroids
    3. Weekly local injections of triamcinolone acetonide
