Dermoscopy of the Month: Dermoscopy of Primary Cutaneous B-Cell Lymphoma


Primary cutaneous B- cell lymphomas (PCBLs) are B-cell malignant neoplasms that originate in the skin, and have no extracutaneous manifestations of disease at the time of diagnosis. PCBLs are classified into three main types: primary cutaneous marginal zone lymphoma (PCMZL), primary cutaneous follicle center lymphoma (PCFCL), and primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL- LT). Dermoscopic characterization of PCBLs has been limited and dermoscopy may help to augment the clinical recognition of PCBLs with the most common dermoscopic findings of salmon colored areas and serpentine vessels. Recognition of dermoscopic features of primary cutaneous B- cell lymphomas can improve the early diagnosis of these tumors and their proper management.
