Can psoriasis develop around the site of an injury? Yes. If you have
psoriasis, lesions have been known to occur on parts of skin that have been
injured. This may include areas of scrapes and scratches, sunburns, or places
where you've received a vaccination. This tendency for psoriasis to appear around
injured areas of skin is called the
Koebner phenomenon. Injuries don't
act as a "trigger" for everyone who has psoriasis; nevertheless, this
phenomenon presents another good reason why you should resist picking and scratching
at psoriais lesions.
