A flow cytometric study of the significance of DNA aneuploidy in cutaneous lesions.
Aneuploidy has not to date been demonstrated in any entirely benign condition and thus is held to be implicit of neoplasia. DNA flow cytometry can be used to detect DNA aneuploidy rapidly. A technique has been developed to make possible flow cytometric analysis of formalin-fixed skin. The technique was validated by study of benign and pre-malignant dermatoses. Further studies were performed on skin conditions of questionable malignant potential. DNA aneuploidy was demonstrated in lichen sclerosus et atrophicus. Flow cytometry was unable to distinguish keratoacanthomas from squamous cell carcinomas.
