Vocal cord nodule, also vocal cord polyp, vocal fold nodule and singer's nodule, is a benign pathology of the head and neck.

General

  • Benign.
  • Etiology: overuse, mechanical trauma (?).

Clinical:

Microscopic

Features:[2]

  • Early:
    1. Edema.
    2. Fibroblasts proliferation.
  • Late:
    1. Subepithelial hyaline / stromal hyaline.
    2. Blood vessels - dilated.

Notes:

  • No inflammation.
