We describe a patient with a disseminated nodular cutaneous B-cell lymphoma, whose diagnosis was finally made after a long series of biopsies in different institutions in Europe and the United States. The differential diagnosis between lymphoma and pseudolymphoma was the recurrent problem throughout the patient's history because histologic and immunophenotypic criteria alone were not sufficient for differentiation. Molecular biology inconsistently detected clonal immunoglobulin rearrangements, which proves that careful clinicopathologic correlation remains mandatory. In contrast to a claimed "high-grade" malignant histology, this lymphoma responded with remission to PUVA therapy combined with intralesional corticosteroids, which is uncommon in the management of cutaneous B-lymphomas.
