Distribution of Langerhans cells in spinocellular epitheliomas

: The authors perform and study about Langerhans cell's distribution on squamous cell carcinomas and on one ecrine porocarcinoma. We used OKT6 and HLA-Dr antigens with fluorescein. We observed a higher density of these cells on the tumors more differentiated. On the other hand, we have seen that tumoral cells of the ecrine porocarcinoma display HLA-Dr antigens.
