Angiocentric lymphoma

Angiocentric lymphoma (also known as "Extranodal natural killer cell lymphoma," "Nasal-type NK lymphoma," "NK/T-cell lymphoma," and "Polymorphic/malignant midline reticulosis" ) is a cutaneous condition which in Korea, is reported to be the most common form of cutaneous lymphoma after mycosis fungoides.

Extranodal NK-T-cell lymphoma is a type of lymphoma.

It is called "extranodal" to emphasize that the location is not in the lymph node. It is sometimes further qualified as "nasal type".

It can be associated with Epstein Barr virus.
