  • Abstract
  • Look Inside

Formalin-fixed, paraffin-embedded laryngeal specimens were stained immunohistochemically with anti-cytokeratin 13 (CK13) and anti-CK19 antibodies. The subjects consist of six laryngeal polyp, two dysplasia, and three squamous cell carcinoma.

In normal epithelia, CK13 was uniformly dis-tributed throughout the suprabasal layers, while CK19 was most pronounced in the basal layer and became progressively reduced in proportion to the upper layers.

In dysplasia, non-staining area was enlarged in CK13 staining, while in CK19 staining, stained area was uniformly distributed.

In squamous cell carcinoma, CK19 was posi-tive in carcinoma cells, but staining became weak when the cells were differentiated. On the other hand CK13 was localized only in the well diffe-rentiated cells.

These findings are useful in evaluating epithe-lial disorders and/or carcinoma of the larynx.
