Koebner phenomenon due to scratch test in scleromyxoedema

Br J Dermatol. 2001 Aug;145(2):306-8. doi: 10.1046/j.1365-2133.2001.04321.x.


The Koebner phenomenon or isomorphic response was originally described in psoriasis and has subsequently been observed in various other diseases. We report a patient with isomorphic response in scleromyxoedema, a variant of papular mucinosis with diffuse infiltration of the skin. The Koebner phenomenon was due to a scratch test performed 4 weeks before the appearance of streaky, lichenoid infiltrations on the forearms.
