Multiple genomic mutations, especially those involving the NF-κB pathway, have been characterized in primary cutaneous large B-cell lymphoma, leg type. However, its genomic profiling remains limited given its rarity. In a recent study, Mareschal et al. performed next-generation sequencing and whole-exome sequencing, identifying new driver genes while also confirming the role of myeloid differentiation primary response gene 88 in the molecular pathogenesis of the disease.
