When initially described, it was believed to be a distinct clinical entity with a pathognomonic histopathologic picture. Through the years we have come to know that, like syphilis, MF is a great masquerader and can present clinically and histopathologically in many ways. This review is an attempt to cover the many faces of MF that have evolved through the years. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.
