Biology professor Leo Buss often warned us that association did not imply causation. While some experienced with basic statistics would recognize that these words are not necessarily linked, this tenet may not be entirely clear to some dermatologists.

Clearly the word association should not be abandoned. It aptly describes an important relationship between two disease states.
