  • Natural killer/natural killer-like T-Cell lymphoma, CD56+, presenting in the skin: An increasingly recognized entity with an aggressive course JOURNAL OF CLINICAL ONCOLOGY Mraz-Gernhard, S., Natkunam, Y., Hoppe, R. T., Leboit, P., Kohler, S., Kim, Y. H. 2001; 19 (8): 2179-2188

    Abstract:

    To describe and identify the clinical and pathologic features of prognostic significance for natural killer (NK) and NK-like T-cell (NK/T-cell) lymphoma presenting in the skin.This study was a retrospective review of 30 patients with CD56+ lymphomas initially presenting with cutaneous lesions, with analysis of clinical and histopathologic parameters.The median survival for all patients was 15 months. Those with extracutaneous manifestations at presentation (11 patients) had a shorter median survival of 7.6 months as compared with those without extracutaneous involvement (17 patients), who had a more favorable median survival of 44.9 months (P =.0001). Age, gender, extent of cutaneous involvement, and initial response to therapy had no statistically significant effect on survival. Seven patients (24%) had detectable Epstein-Barr virus (EBV) within neoplastic cells. The patients with tumor cells that coexpress CD30 (seven patients) have not yet reached a median survival after 35 months of follow-up as compared with those with CD30- tumor cells (20 patients), who had a median survival of 9.6 months (P <.02). Routine histopathologic characteristics had no prognostic significance nor did the presence of CD3epsilon, EBV, or multidrug resistance.NK/T-cell lymphoma is an aggressive neoplasm; however, a subset with a more favorable outcome is identified in this study. The presence of extracutaneous disease at presentation is the most important clinical variable and portends a poor prognosis. The extent of initial skin involvement does not reliably predict outcome. Patients from the United States with NK/T-cell lymphoma presenting in the skin have a low incidence of demonstrable EBV in their tumor cells. Patients with coexpression of CD30 in CD56 lymphomas tend to have a more favorable outcome.
