[A woman with a painful swelling of the upper arm]. / Een vrouw met een pijnlijke zwelling van de bovenarm.

A 81-year-old woman presented at the emergency department with a painful right arm due to a comminuted fracture of the humeral head. Operation was postponed because of a wound and vulnerable skin due to a large hematoma. By the time of the operation, the humeral head had migrated subcutaneously which resulted in a solid swelling of the upper arm.
