Angiofollicular hyperplasia

The original description of angiofollicular hyperplasia was of a case of localised mediastinal lymph node hyperplasia in 1954 and later described in more detail in 1956 resulting in the alternative names Castleman disease and Castleman's disease.[1] Now taken to refer, more broadly, to a more heterogenous group of lymph node hyperplasia. Also known as giant lymph node hyperplasia.

It is regarded as a lymphoproliferative disorder, although infective agents such as HHV-8 may be implicated in some cases where production of a viral homologue of interleukin 6 is thought to drive the disease.[2][3][4][5]

The disorder can be unicentric or multicentric, the latter having a stronger association with HHV-8. However, the histological classification appears to correlate better with systems and is divided into the hyaline vascular variant (90% unicentric) and the plasmacytic variant (more likely to be multicentric),[6] though a mixed cellularity variant is also described. TAFRO syndrome a form of multicentric angiofollicular hyperplasia has been recently described[7].

Treatment consists of excision in the unicentric type, but various drugs have been tried including steroids and various cytokine inhibitors, in particular IL-6 inhibitors, e.g. tocilizumab or siltuximab.[8] Rituximab and other chemotherapeutic drugs have also used.
