48 - Evaluation of Bone Lesions Around the Hip

Abstract

Characteristics that make an osseous lesion more likely to be malignant include an associated soft tissue mass, periosteal elevation, a permeative appearance, large size, and rapid growth. A well-planned biopsy is critical and should be undertaken (or at least directed) by the surgeon performing the definitive procedure. Metastatic disease and hematopoietic disease (multiple myeloma, lymphoma) are far more common than is primary disease (such as sarcoma) in an adult. Most active and aggressive benign osseous tumors are treated by extensive curettage with or without adjuvants (e.g., liquid nitrogen, argon beam coagulator, or phenol). Among bone sarcomas found in the hip, Ewing sarcoma is most common in children and chondrosarcoma is most common in adults.
