title: Extramammary Paget's disease of the penis: a case report and review of the literature.
abstract: BACKGROUND
  Extramammary Paget's disease is a rare cutaneous, slow growing, intraepithelial adenocarcinoma developing in the apocrine gland-bearing areas. Isolated Paget's disease of the penis is extremely rare.
  
  
  METHODS
  We describe the case of an 87-year-old Caucasian male who presented with a non-healing erythematous plaque on the shaft of the penis previously misdiagnosed as Bowen's disease. The diagnosis was made histologically on the excised specimen and was supported by immunohistochemical staining.
  
  
  CONCLUSIONS
  Extramammary Paget's disease is a rare disease which can mimic various types of dermatosis. A high index of suspicion is required, combined with biopsy and immunohistochemical staining in order to make the correct diagnosis. Long-term follow-up is mandatory in these patients in order to identify and treat any subsequent recurrence or concurrent malignancy.
