- For use of the term nodule in dermatology, see Cutaneous condition: Nodule
In
medicine nodules are solid, non-blisterform elevated areas in or under the skin that are larger than 0.5 centimeters. Nodules may form on
tendons and
muscles in response to injury. The
vocal cords may also develop nodules. Nodules are normally
benign and often painless, although they can affect the functioning of the
organ.
