Bone changes in primary myogenic limb sarcomas

Of 55 patients with histologically varified primary myogenic limb sarcomas the authors observed 5 patients with rhabdomyosarcoma (RMS) and 2 with leiomyosarcoma (LMS) of the limbs accompanied by bone changes. RMS was characterized by an infiltrative type of bone involvement by a tumor (inhomogeneous edge destruction of varying depth), and bone atrophy was noted in the zone of contact with a tumor in LMS
