Cutaneous T-cell lyrr,iphomas other than mycosis fungoides and S6zary syndrome are heterogeneous : they deseve further scientific attention about their natural history and effective therapy. Pleomorphic T-cell lymphoma is a recently defined lymphoma type that can occur in the skin. We report the case of a man in whom such a tumor manifested itself with mult,iple subcuta- neous lesions. The skin b!opsy specimen showed diffuse dermal infiltration of atypical lymphocytes with highly pleomorphic nuclei. Testing for the antibody against HTLV-1 was negative and immunohistochemical staiiiing was compatible with pleomorphic T-cell lymphoma. (Korean J Dermatol 1997;35(6): 1258-1262)
