Rheumatologic manifestations of benign and malignant haematological disorders.

Diseases of blood and lymphoreticular system can have multisystem manifestations. Rheumatologic involvement has been reported in association with many benign and malignant haematological disorders; these patients are equally likely to present to both clinical rheumatologists and haematologists. This review focuses on the well-described rheumatologic features, other occasionally reported rheumatologic manifestations and unusual musculoskeletal complications related to the treatment in patients with underlying haematological conditions. The aim of this review is to help increase the awareness of rheumatologic manifestations seen in the blood disorders and to highlight the potential diagnostic pitfalls.
