Salmon-colored area and serpentine blood vessels in primary cutaneous marginal zone 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.[1] Although not specific, the most common dermoscopic features are salmon-colored background/area and blood vessels, most frequently serpentine (linear irregular) vessels.[1] White circles were also reported to be a common finding.[2] 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.
