In adult T-cell leukemia/lymphoma, the cutaneous nodules show a superficial or more diffuse infiltration of medium to large T cells with pleomorphic or multilobated nuclei, often with marked epidermotropism. The histologic picture may be the same as that seen with mycosis fungoides. In the smoldering type of adult T-cell leukemia/lymphoma, dermal infiltrates may be sparse, with only slightly atypical cells.
