title: Multifocal skin basal cell carcinomata 57 years after topical dry ice treatment.
abstract: We report a rare case of simultaneous multiple basal cell carcinomata occurring on the back of a patient who had received dry ice treatment to this area almost 6 decades previously. This is also one of the longest recorded disease-free intervals between skin trauma and basal cell carcinoma development. We discuss the aetiopathology of multiple skin cancers in our patient and the propensity for destructive skin events to predispose to malignancy.
