Is it true that getting a skin scrape can lead to a psoriatic lesion?
Yes. Psoriasis patients can develop lesions at the site of significant skin trauma, especially during a period of active disease. Psoriasis worsens in areas of skin scrapes, scratches, and cuts (such as surgical wounds). That’s why it is so important not to pick, scratch, or scrub the lesions and scales. The development of a psoriatic lesion at the site of skin trauma is called Koebner’s phenomenon.
