Cutaneous B-cell lymphoma
Only few studies evaluated the diagnostic value of dermoscopy in cutaneous B-cell lymphomas. Primary cutaneous B-cell lymphomas are classified into 3 main types: primary cutaneous marginal zone lymphoma, primary cutaneous follicle center lymphoma, and primary cutaneous diffuse large B-cell lymphoma – leg type, and all three types show similar dermoscopic characteristics. Although not specific, the most common dermoscopic features are salmon-colored background/area and blood vessels, most frequently serpentine (linear irregular) vessels. White circles were also reported to be a common finding. Other vascular morphologies, scaling or ulceration can be seen less frequently.
Dermoscopy can assist in distinguishing between cutaneous B-cell lymphoma and other differential diagnoses that present as solitary or grouped pink lesions.
