Pleomorphic peripheral T-cell lymphomas (PPTL) arising primarily in the skin are uncommon. The observation of pleomorphic T-cell lymphoma composed of 100% CD30+ cells is rare. We report the case of a woman in whom such a tumor manifested itself with a single cutaneous lesion. It was composed of medium to large cells expressing markers of helper/inducer T-lymphocytes, as well as activation (CD30) and proliferation antigens (Ki-67), but not the CD25 activation antigen. The lesion was excised and the patient is alive and disease free 2 years after the diagnosis. This case confirms previous reports about the favorable course of some cutaneous pleomorphic lymphomas, and shows that the activation antigen expression and proliferation antigen (Ki-67) expression do not seem to worsen the prognosis.
