title: Radiological reasoning: male breast mass with calcifications.
abstract: OBJECTIVE
  We encountered a mammographically calcified breast mass in a 30-year-old man. It was initially thought to be comedo-type ductal carcinoma in situ because of the dense calcifications, but sonography and MRI suggested a highly vascular lesion. The final pathologic diagnosis was hemangioma.
  
  
  CONCLUSIONS
  Vascular tumors of the breast occur infrequently and are even more rare in males. The clinical and radiologic diagnosis of breast hemangioma is often difficult, but different imaging techniques, when used together, can provide important information for differential diagnosis and management. A biopsy is required.
