Granulomatous slack skin: A rare subtype of mycosis fungoides

We report a case of granulomatous slack skin,a rare and indolent subtype of mycosis fungoides. it affects mainly men between the third and fourth decades. it is characterized by hardened and erithematous plaques that mainly affect flex-ural areas and become pedunculated after some years. histological examination shows a dense infiltrate of small atypical lymphocytes involving the dermis (and sometimes the subcutaneous tissue) associated with histiocytic and multinucleated giant cells containing lymphocytes and elastic fibers (lymphophagocytosis and elastophagocytosis,respectively). patients affected by this entity can develop secondary lymphomas. there are several but little effective therapeutic modalities described. despite the indolent behavior of granulomatous slack skin,its early recognition and continuous monitoring by a dermatologist becomes essential for its management and prevention of an unfavorable outcome. © 2017 by anais brasileiros de dermatologia.
