Primary cutaneous blastic natural killer cell lymphoma.

چکیده
Sir, Blastic natural killer-cell lymphoma, also called “agranular CD4+ CD56+ haematodermic neoplasm” is an uncommon type of tumour, which is included in the new World Health Organization (WHO) classification as a malignancy derived from natural killer (NK) cells. It is very aggressive, affecting many organs, and skin involvement is highly characteristic. Several origins have been proposed, but recent studies have shown a relationship with plasmocytoid monocytes. We report here a new case of this rare lymphoma, with skin infiltration as the first manifestation, and with early dissemination to bone marrow and central nervous system (CNS).
