Incidence and characteristics of CD4(+)/HLA DRhi dendritic cell malignancies.

Abstract

We show that DC-derived malignancies can present as either cutaneous lymphoma or acute leukemia, although their incidence is extremely low (<< >1%). While most of these DC neoplasias probably correspond to the malignant counterpart of DC2/lymphoplasmacytoid DC, neoplasias of myeloid DC might also exist, chemotherapy followed by consolidation with ASCT is apparently the most effective strategy for achieving a durable remission in these individuals.
