title: Bone lesions in chronic granulocytic leukaemia.
abstract: Radiographic abnormalities in bone are unusual during the stable phase of chronic granulocytic leukaemia (CGL). A rare situation is reported in which a patient developed three distinctive skeletal lesions simultaneously in different anatomical sites. Firstly, in both fibulae symmetrical punched out and permeative lesions were present throughout much of the shafts, being most prominent in the mid-diaphyseal regions. Secondly, the tibiae were slightly porotic and showed localized periosteal reactions, whereas in the fibulae there was extensive cloaking by a similar but much more intensive reaction. Thirdly, multiple osteosclerotic lesions were present in the pubic bones and in the proximal ends of the femora and humeri. Concurrently, fluctuant, culture negative swellings were present on the extremities. Histological examination of the material from the subcutaneous and lytic lesions showed only areas of fibrosis with islands of haematopoietic tissue, including scanty megakaryocytes. Bone marrow trephine biopsy showed the presence of myelofibrosis with islands of haematopoietic tissue typical of CGL without any evidence of blastic transformation.
