Carcinoma, which has predilection for metastasis to hands and feet bones: March 2007

Ans. B: Bronchus In adults, the metastatic lesions generally occur in the axial skeleton and other sites with residual red marrow, although the lesions may be found anywhere in the skeletal system. Common sites for metastases are the veebrae, pelvis, proximal pas of the femur, ribs, proximal pa of the humerus, and skull. Ceain carcinomas may have a predilection for paicular skeletal sites. For example, metastases to the bones of the hands and feet are rare, but 500/0 of hand metastases originate from lung neoplasms Primary tumors arising from the pelvis have a predilection for spread to the lumbosacral spine.
