Koebner phenomenon caused by bloodletting and cupping therapy in a patient with psoriasis

Stoyan Pavlov, Milka Dimitrova


The Koebner phenomenon refers to the appearance of isomorphic lesions on areas of cutaneous injury in otherwise healthy skin areas. This is a common skin reaction presented by the German dermatologist Heinrich Koebner (1838–1904) in 1872. In addition to the name Koebner phenomenon, it is also called the isomorphic response. We report a case of a 26-year-old man with a 10-year history of psoriasis vulgaris. The patient had been treated with bloodletting and cupping therapy for chronic back pain and developed psoriatic papules and plaques in the places of injuries. The presented case confirms the role of iatrogenic trauma as a trigger for the formation of psoriatic plaques in patients with clinically manifested disease.
