We describe a patient with a 2-month history of right shoulder monoarthritis and fever as the presenting symptoms of a subsequent diagnosis of chronic myeloid leukemia in blast crisis. Imaging studies showed changes consistent with leukemic infiltration of the soft tissues around the right shoulder joint and the proximal humerus. Immunophenotypic and morphologic analysis of the large number of cells obtained from the synovial fluid confirmed the shoulder synovitis to be an extramedullary manifestation of myelomonocytic blast crisis of chronic myeloid leukemia. The patient was not a candidate for aggressive chemotherapy treatment because of her poor overall condition, and she had no compatible donor for allogenic bone marrow transplantation. Her painful arthropathy was refractory to standard pain management but she achieved excellent pain relief with palliative radiation therapy. We conclude that the involvement of extramedullary sites by chronic myeloid leukemia blast cells can predate hematological blast crisis in some of chronic myeloid leukemia cases. Also, painful leukemic synovitis can be managed by low dose radiotherapy in a candidate who is refractory to chemotherapy and other medical therapy.

We present a previously unreported case of rapidly progressing, destructive shoulder arthropathy as an initial presentation of chronic phase chronic myeloid leukaemia. This patient initially presented to clinic for consideration of an arthroplasty for symptom relief; however, her loss to follow-up yielded a rapid progression of her symptoms. Bone marrow aspirate and targeted biopsy of the humeral head excluded blast cell crisis, in contrast to previously reported cases. She was treated conservatively with medical management of her underlying disease. Although leukaemic arthritis is a recognized phenomenon, chronic myeloid leukaemia is not known to cause bone destruction of this kind, particularly in the absence of blast crisis. Medical treatment with a tyrosine kinase inhibitor provided a dramatic improvement in our patient's pain, without the risk of attempted arthroplasty in unknown bone quality. We describe a unique presentation of severe bone destruction as a manifestation of chronic myeloid leukaemia in the absence of blast crisis. This should be considered as a rare differential diagnosis in joint arthropathy and may be appropriately managed initially with medical therapy, whereas future arthroplasty comprises uncharted territory in unknown bone quality.
