Exams and Tests

Prior to removal of superficial dermoid cysts on the face, a person should know the difference between cysts and other facial growths.

• Because dermoid cysts stem from birth and grow slowly, a person usually notices them during childhood or early adulthood.
  
  
• Dermoid cysts are firm and painless unless ruptured.
  
  
• Dermoid cysts are not attached to the overlying skin.
  
  

In rare cases, a dermoid cyst extends into a structure deeper than skin, such as a facial cavity or an orbit. Some doctors recommend a CT scan or other imaging studies for these cases. This decision depends on the doctor's suspicion of a deep-level cyst and after a determination of risk versus benefit.
