[Bone lesions in hairy cell leukaemia (author's transl)].

Between 1959 and 1978, 150 patients with tricholeucocytic leukaemia were seen, 5 having radiological bone lesions. This has been reported only once in the literature, its significance and therapeutic consequences remaining ill-defined. One of the commonest sites of bone involvement is the neck of the femur. The usual appearances are those of demineralisation, lysis and pathological fracture. The true prevalence of such lesions could be determined only by routine studies for the presence of such lesions.
