Induration (in'doo rā'shən, -dyoo-), a noun, means, in terms of pathology, (a) hardening of an area of the body as a reaction to inflammation, hyperemia, or neoplastic infiltration, or (b) an area or part of the body that has undergone such a reaction.[1] Most often this term is used to describe dermatologic findings.
