title: Categorization of and comments on isomorphic and isotopic skin reactions.
abstract: Locus minoris resistentiae (lmr) can be defined as a site of the body that offers lesser resistance than the rest of the body to the onset of disease. The well-known Köbner phenomenon is itself a clear example of lmr in dermatology. The new term locus maioris resistentiae (LMR), a site of the body that offers greater resistance than the rest of the body to the onset of disease, defines the opposite condition. Renbök phenomenon (reverse Köbner's isomorphic response) typically represents an example of LMR.
