Recurrent Primary Cutaneous Anaplastic Large Cell Lymphoma With T-Cell Receptor-ϒδ Phenotype and DUSP22-IRF4 Unbalanced Rearrangement: A Rare and Diagnostically Challenging Presentation.
ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is an indolent CD30+ T-cell lymphoma, typically of T-cell receptor (TCR)-αβ origin with an excellent prognosis. Rare cases may exhibit a TCR-ϒδ phenotype or rearrangement of the DUSP22 and IRF4 genes on chromosome 6p25.3, but the concurrence of both fea...
