John Updike and Blue Light: From Psoriasis to Photodynamic Therapy

Arch Dermatol. 2012;148(3):407. doi:10.1001/archdermatol.2011.2826

“Fritz Fleischer's epidermis —plagued by psoriasis in childhood, then by sun damage in old age — ” develops actinic keratoses. With these words of his alter ego, John Updike (1932-2009) summarizes the consequences of the treatment for his almost lifelong psoriasis.1 Because his old dermatologist had died, Fleischer sought help from a young dermatologist “who gave the impression that all of the things that exist  .  .  .  the one that interested him least was human skin. ” He explained to Fleischer in detail the new technology of photodynamic therapy to “flush out precancerous cells. Before they turn cancerous. ”
