title: Cutaneous extranasal NK/T-cell lymphoma.
abstract: Malignant neoplasm from natural killer (NK) cells are characterized by their positivity for CD56 and absence of monoclonal TCR gene rearrangement. We present the case of a 54-year-old man with a fungous mass in his left flank whose histological examination was consistent with cutaneous extranasal T/NK cell lymphoma. We review the literature and also discuss the prognosis and treatment of this variety of lymphoma.
