title: Anaplastic large-cell T-cell lymphoma.
abstract: A 64-year-old woman presented with 2 years of pruritic and ulcerated nodules and tumors on the trunk and arms. Histopathologic examination showed a diffuse infiltrate that consisted of predominantly small lymphocytes and scattered large atypical multinucleated cells positive for CD30. These findings were consistent with a diagnosis of anaplastic large-cell T-cell lymphoma, which is a CD30+ cutaneous lymphoma. This case highlights the importance of considering both histopathologic and clinical criteria in diagnosing a patient with a CD30+ cutaneous lymphoma.
