title: Pyoderma gangrenosum-like oral ulcerations in an elderly patient.
abstract: OBJECTIVE
  To present a case of pyoderma gangrenosum (PG)-like oral ulcerations in an elderly patient.
  
  
  BACKGROUND
  PG is an uncommon idiopathic, ulcerative, chronic inflammatory cutaneous disorder of unknown etiology, which is associated with systemic diseases found in more than 50% of patients. Oral lesions of PG are extremely rare and have not been previously reported on chronic leukemia patient.
  
  
  METHODS
  This report presents the first case of a 73 year-old man who had PG-like oral ulcerations which offered the possibility of an initial finding of chronic myeloid leukemia.
  
  
  CONCLUSIONS
  Clinicians should always take into consideration that PG in the oral mucosa is a recalcitrant ulcer and can precede the development of underlying clonal malignancy.
