Ultrasound of Common Non-vascular Benign Cutaneous Lesions

  • Ximena Wortsman
Chapter

Abstract

This chapter reviews the sonographic appearance of common non-vascular benign cutaneous lesions, focusing on the ultrasound patterns for each entity. Both cutaneous benign tumors and pseudotumors are characterized and the relevant points for each condition are provided.
