T-Cell Lymphoblastic Lymphoma/Leukemia Presenting as a Diffuse Viral Exanthem-like Reaction: A Clinical and...

Cutaneous involvement by leukemia, or leukemia cutis, is a rare manifestation of leukemic disorders, most frequently occurring in children. The skin findings, which usually include multiple violaceous or erythematous nodules on the face, most often follow the classic presenting signs and symptoms of leukemia and occur in patients with an established primary diagnosis. Patients with T-cell acute lymphoblastic leukemia and associated leukemia cutis typically present with a solitary firm red to bluish nodule, often with an accompanying mediastinal mass, that can produce respiratory symptoms. In this article, we report a case of a patient with primary T-cell acute lymphoblastic leukemia/lymphoma presenting with a diffuse exanthem mimicking a viral illness with an associated SET-NUP214 translocation.
