KEY FACTS

  • Terminology

    • Imaging

      • Pathology

        • Clinical Issues

          TERMINOLOGY

          • Definitions

            • Benign smooth muscle tumor that occurs in skin, subcutaneous tissues, or deep soft tissues
            • Clinical groups
              • (1) Cutaneous leiomyoma (leiomyoma cutis)
                • Includes genital leiomyomas and piloleiomyomas
              • (2) Angioleiomyomas (angiomyoma or vascular leiomyoma)
                • Typically subcutaneous
                • From tunica media of vein
              • (3) Leiomyoma of deep soft tissues
                • Deep soft tissues of extremity or retroperitoneum (females)
                • Much less common than superficial types
                • Can be confused with leiomyosarcoma, which is more common
