Why wasn't primary cutaneous marginal zone extranodal B-cell non-Hodgkin's lymphoma mentioned?
It actually was mentioned! Primary cutaneous marginal zone B-cell lymphoma is a recognized subtype of cutaneous B-cell lymphoma (CBCL). It's described as an indolent (slow-growing) disease that typically forms red skin lesions on the torso and arms.
This type falls under the broader category of marginal zone lymphomas, which are extranodal (meaning they occur outside the lymph nodes). In this case, it specifically affects the skin.
Primary cutaneous marginal zone B-cell lymphoma is one of the less aggressive forms of CBCL and may not always require immediate treatment. Some people with this subtype are managed through active surveillance (watch-and-wait approach).
Because it's a skin lymphoma, it's present only in the skin at the time of diagnosis, not in other parts of the body.
