A Transplantable Induced Melanotic Tumor of the Syrian Golden Hamster*

The present paper records the availability of a new transplantable melanotic tumor in the Syrian golden hamster. A previous report (1) described the induction of multiple pigmented tumors in the Syrian golden hamster following the application to the skin of a single dose of the carcinogen 9,10dimethyl-l,2-benzanthracene. These tumors were sharply demarcated and located in the dermis and subcuta...
