Congenital and genetic skin disorders with tumor formation.
There are a great number of genetic and congenital disorders with skin manifestations ("genodermatoses") with tumor formation. Some of these tumors are benign (hamartomas, in part) and others are malignant. There is a large group of heredodegenerative disorders with such complications as lymphosarcoma and leukemia. There are congenital tumors with malignancy developing. Lastly, there are the chromosomal abnormalities with skin manifestations and tumors, usually malignant. This will be an ever increasing field and the use of fibroblast and virus cultures will become more important in ascertaining the cause of malignancy.
