Which of the following conditions gives a positive Pathergy test?
Correct Answer: Behcet's disease
Description: The pathergy test is the hyper-reactivity of the skin to trauma. A skin trauma like needle prick will produce a papule or a pustule, surrounded by an erythematous reaction, at the site of the trauma. This curious phenomenon is almost unique to Behcet's syndrome.
