    Abstract

    We describe the clinical and pathologic observation of a 50-year-old man with superficial disseminated porokeratosis who developed a squamous cell carcinoma on the dorsum of his right thumb and Bowens disease on his right upper arm. The tumors were surrounded by lesions of superficial disseminated porokeratosis and were thought to develop from the dysplastic epidermal cells located under the comoid lamellae.
