A nodule is morphologically similar to a papule, but is greater than 1 cm in diameter, and most frequently centered in the dermis or subcutaneous fat.^{[1][nb 1]} On examination, however, depth of involvement and/or substantive palpability, rather than frank diameter, differentiate a nodule from a papule.^[2]

1. ^ With regard to the quote "...but are greater than 1 cm in diameter," depending on which text is referenced, different authors state different diameters for defining a nodule. Therefore, for this article, the 1cm cutoff is used which is discussed in Andrews' Diseases of the Skin: Clinical Dermatology (see references), a work considered by some dermatologists^[who?] as an authority on this subject matter.
