Cutaneous B-cell lymphomas constitute a group of diseases that occur less commonly than
cutaneous T-cell lymphoma
Cutaneous T-cell lymphoma (CTCL) is a class of non-Hodgkin lymphoma, which is a type of cancer of the immune system. Unlike most non-Hodgkin lymphomas (which are generally B-cell-related), CTCL is caused by a mutation of T cells. The cancerous ...
