Cutaneous B-cell lymphoma

Cutaneous B-cell lymphomas constitute a group of diseases that occur less commonly than cutaneous T-cell lymphoma, and are characterized histologically by B-cells that appear similar to those normally found in germinal centers of lymph nodes.^[1]^:741 Conditions included in this group are:^[1]^:740–743
