Overview

Other diagnostic studies for glomus tumor include immunohistochemistry staining, which demonstrates glomus cells positive for vimentin and alpha-smooth muscle actin and negative for desmin.[1]

Other Diagnostic Studies

  • Other diagnostic studies for glomus tumor include immunohistochemistry staining, which demonstrates the following:[1]
    • Glomus cells stain positive for:
      • Vimentin
      • Alpha-smooth muscle actin (~100%)
    • Glomus cells stain negative for:
      • Desmin
      • CD34 (rarely positive)
      • S100
