Squamous cell carcinoma arising from a lesion of disseminated superficial actinic porokeratosis.
We report a 69-year-old man with disseminated superficial actinic porokeratosis (DSAP) who developed a hyperkeratotic lesion on the distal third of the right forearm with the characteristic histopathological findings of squamous cell carcinoma and DSAP. A review of the literature revealed only four similar cases.
