- Nodule (medicine)
For use of the term nodule in dermatology, see Nodule (dermatology)
In medicine, a nodule refers to a relatively hard, roughly spherical abnormal structure.
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.
Furuncles and Kaposi's sarcomae are known to cause dermatological nodules.
