Utilidad de la tinción con laminina-332 para diferenciar queratoacantoma, queratoacantoma con áreas de carcinoma epidermoide y carcinoma epidermoide crateriforme

Laminin-322 staining is different in keratoacanthomas and SCCs and would thus be a useful test for differentiating keratoacanthomas from both invasive SCCs and keratoacanthomas with areas of squamous cell carcinoma. It would also be of value in diagnosing keratoacanthomas with areas suggestive of SCC or with incipient SCC.
