Granulomatous slack skin (GSS) is a subtle variant of mycosis fungoides that is easily overlooked on initial biopsy due to its well-formed granulomatous appearance (1). The initial clinical presentation is similar to that of conventional mycosis fungoides in that patients present with erythematous-to-violaceous patches and plaques. As the lesions progress, however, pendulous folds develop on flexural surfaces of extremities, especially the axillae and inguinal regions (Figure 3.1). Less commonly, the skin on the trunk is affected. At this point in the course of the disease, the clinical appearance is similar to that of cutis laxa. This extremely rare variant of mycosis fungoides affects middle-aged adults with a slight predilection for women in some, but not all, series (2–5). It is most common in Caucasians.
