title: Bilateral ductal carcinoma in situ (DCIS) in a male breast: a case report.
abstract: OBJECTIVE
  This case is presented to emphasize the importance of recognizing nipple discharge as a clinical sign of male ductal carcinoma in situ and an opportunity for early diagnosis.
  
  
  METHODS
  A 68-years old gentleman presented with bilateral bloody nipple discharge. Clinical examination of breasts showed no masses in either breasts and no axillary lymphadenopathy. He was investigated with bilateral mammogram, ultrasound scan and magnetic resonance imaging of the breasts. All were leading to a diagnosis of intraductal papilloma on the left retroareolar region and suspicious microcalcifications on the right retroareolar area. Retroareolar excision under general anesthesia confirmed the presence of DCIS in both specimens. Completion mastectomy was performed which showed no residual disease in either breasts.
  
  
  CONCLUSIONS
  DCIS in male breast is very rare and hard to diagnose due to male breast morphology. It is best treated with mastectomy without axillary dissection.
