About 75% of cutaneous lymphomas belong to the group of T-cell lymphomas, M
ycosis fungoides is the most common entity in this group. Granulomatous sla
ck skin is a rare form of cutaneous T-cell lymphoma closely related to myco
sis fungoides, We present here a patient with areas of lax skin for several
years who developed a generalized erythroderma with associated immunoactiv
ation and a deterioration in his general condition, This report discusses c
linically and histologically the differential diagnoses, namely granulomato
us slack skin and granulomatous mycosis fungoides, and suggests that these
2 disorders are only variants in the broad spectrum of a single disease.
