Polyarteritis nodosa and acute myeloid leukaemia

Rheumatological manifestations of the leukaemias and graft versus host disease

Bone and joint involvement in the leukaemias is discussed. Particular emphasis is placed upon osteoarticular presentations which may predate the haematological changes or divert attention from the primary pathology. A description of acute and chronic graft versus host disease is presented with particular emphasis on the rheumatological manifestations.
