Granulomatous slack skin (GSS) represents a rare variant ofmycosis fungoides, histologically characterized by a variably deep T helper lymphocytes infiltrate with alteration of the dermal elastic tissue and consequent elastolysis, elastophagocytosis and numerous giant cells. Clinically, a development of unelastic, slack skin, especially on flexural areas, is observed. Hereby, we describe a man with a 12-year history of GSS. In 2002, for practical (limitation of movement, deambulation) and cosmetic reasons, he underwent the surgical excision of loose and sagging skinfold over inguinal area, and, afterwards, of the opposite affected inguinal skin. The surgical treatment of bilateral inguinal hernia with reposition of inguinal dislocated vasculature is also reported. In both cases the excised material confirmed the former diagnosis of GSS and revealed a very deep, muscular infiltrate of neoplastic lymphocytes. One year later, a new excision of GSS on the axillae was made. Now, after 2 years, deambulation keeps improving, although an initial relapse of the inguinal slack skin has been observed. 展开更多
