Spontaneous chest wall haematoma in chronic myeloid leukaemia

Chronic myeloid leukaemia can have different presenting signs. Here, we present a case of nontraumatic spontaneous chest wall haematoma in an 84-year-old man under investigation for myeloproliferative disorder before his admission. He was admitted with a 2-day history of sudden onset posterior chest wall pain and progressive bruises. Computed tomography showed a chest wall haematoma, while blood tests found a mild coagulation abnormality. He required fresh frozen plasma and red blood cell transfusions as part of his management, but his symptoms improved after starting hydroxycarbamide.
