• Lentigo maligna melanoma developed in a patient with a 41-year history of psoriasis. The patient had received substantial radiation therapy and limited tar and ultraviolet energy therapy to the site at which melanoma developed. We raise the question of whether the carcinogenic modalities used to treat the patient may have influenced the development of melanoma.
