title: The head-tilt maneuver: a clinical aid in recognizing head and neck angiosarcomas.
abstract: BACKGROUND
  Cutaneous angiosarcoma is a rare, life-threatening tumor that is often initially misdiagnosed. This delay in diagnosis can affect tumor growth, metastatic potential, and prognosis.
  
  
  METHODS
  We describe the "head-tilt maneuver," which highlights the vascular nature of these lesions and can be of potential benefit in early recognition and better appreciation of the clinical extent of this tumor.
  
  
  CONCLUSIONS
  Early recognition and aggressive management of these tumors can afford the best opportunity for cure.
