Skin Pseudocyst


A skin pseudocyst is a pocket of fluid that forms under the skin. The most common areas for a skin pseudocyst to form are a finger or toe. The ear is possible but less common. A skin pseudocyst may develop after long-term irritation or repeated injury to the area.


Return to the emergency department if:

  • You have red streaks or extreme pain near your wound.
  • Blood soaks through your bandage.

Call you doctor or dermatologist if:

  • Fluid builds up again in the same area.
  • Your incision becomes red, swollen, or painful.
  • You cannot bend your finger or toe.
  • You have questions or concerns about your condition or care.


may include any of the following:

  • Pressure may be recommended if the skin pseudocyst is on your finger or toe and you do not have symptoms. Apply firm pressure on the skin pseudocyst every day for several weeks as directed.
  • Procedures to drain the fluid will be done if the skin pseudocyst is on your ear. Drainage may be done if the skin pseudocyst is on your finger or toe and causes pain or stiffness. Your healthcare provider may use a needle, or he or she may make a small incision to drain the fluid. A sample of the fluid may be sent to a lab for testing.
  • Medicine may be injected into the pocket of fluid to reduce swelling and help the skin pseudocyst heal.

Follow up with your doctor or dermatologist as directed:

You may need to return to have your incision checked or stitches removed. Write down your questions so you remember to ask them during your visits.
