Haematological features of angioimmunoblastic lymphadenopathy with dysproteinaemia.

A study of seven patients with AILD has confirmed previously reported cytological and immunological changes in the peripheral blood. In themselves these changes should not be considered as specific. Histological examination of the bone marrow may show more characteristic lesions which involve haemopoietic, lymphoid, and stromal cells. Three patients had bone marrow features similar to myelofibrosis, which are considered to be diagnostic of AILD.
