The mantle zone (or just mantle) of a lymphatic nodule (or lymphatic follicle) is an outer ring of small lymphocytes surrounding a germinal center.[1]

It is also known as the "corona".[2]

It contains transient lymphocytes.[3]

It is the location of the lymphoma in mantle cell lymphoma.

Pathology

Intermediate magnification micrograph of Castleman disease showing the characteristic expansion of the mantle zone. H&E stain.

Mantle zone expansion may be seen in benign, such as Castleman disease, and malignancy, i.e. Mantle cell lymphoma.
