Cutaneous-type adult T-cell leukemia/lymphoma presenting as a solitary large skin nodule: A review of the literature

Abstract

Adult T-cell leukemia/lymphoma (ATLL) often involves the skin. Cases with skin lesions without either leukemic nor lymph node involvement have been categorized into a cutaneous type. While the clinical manifestations of the cutaneous-type ATLL are variable, including multiple papules, nodules, plaques, or erythroderma, a solitary skin nodule alone is rare, and only 2 cases have been reported in the literature. We present a 58-year-old Japanese patient with cutaneous-type ATLL that presented as a large, solitary skin nodule as the sole clinical feature. The skin tumor was completely resolved after treatment with x-ray and electron beam irradiation.
