Protein S-100 immunostaining as a diagnostic tool for DMBA-induced melanotic lesions.

Abstract

In the present study we demonstrate immunohistochemically the presence of S-100 protein in numerous melanotic and amelanotic lesions (benign, premalignant and malignant) induced in albino guinea-pigs on topical application of the carcinogen. Positive staining was also present in all their amelanotic metastases. We reiterate the value of this stain in the… (More)
