Preface A Contemporary Approach to Soft Tissue Tumors

摘要

Soft tissue sarcomas are a diverse and diagnosti-cally challenging group of malignancies that may arise at any anatomic site. Classification of these tumors relies on morphology (e.g. spindle cell, round cell, epithelioid, or pleomorphic), line of differentiation (e.g. smooth muscle, vascular, adipo-cytic, skeletal muscle, nerve sheath, or unrelated to normal tissue lineages), and genomic features (specific gene-fusion, mutation driven, complex karyotype), and the differential diagnosis may vary depending on the tumor site, patient age, and sex.
