Cutaneous adult T-cell leukemia/lymphoma mimicking primary cutaneous anaplastic large-cell lymphoma

摘要

Tumor cells of adult T-cell leukemia/lymphoma (ATLL), which are likely derived from cells with the T-regulatory phenotype, sometimes express CD30 and such cases are clinically and pathologically almost indistinguishable from anaplastic large-cell lymphoma. Here, we report a case of ATLL mimicking primary cutaneous anaplastic large-cell lymphoma (pcALCL).
