Encyclopedia
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 center

s. Conditions included in this group are:
Germinal center

- PlasmacytomaPlasmacytomaPlasmacytoma refers to a malignant plasma cell tumor growing within soft tissue or within the skeleton. The skeletal forms usually have other occult tumors and frequently disseminate to multiple myeloma over the course of 5–10 years. The soft tissue forms most often occur in the upper respiratory...
