FATAL KERATOMAS DUE TO DEEP HOMOGRAFTS OF THE BENIGN PAPILLOMAS OF TARRED MOUSE SKIN

Abstract

Six out of eight epidermal papillomas, induced with tar in mice of homogeneous strain, have grown after transfer to the subcutaneous tissue of sucklings and weanlings. Five of them have been thus maintained for nearly or quite a year and a half, and in seven to nine successive groups of mice. The tumor studied longest has been kept going in five parallel lines since its primary implantation.
