Text Extraction

In the last three years, fifteen papillated carcinomas in situ with the appearance of irritated wart have been seen at the Skin Cancer Center in Campinas, Brazil. These are tumours that arise de novo in sun-damaged, hairy skin of older Caucasians. The patients refer that these lesions appear suddenly and grow rapidly, as elevated keratotic papules, present particularly on the face and neck and the dorsum of hands and forearms. They are excised with a clinical suspicion of keratoacanthoma, squamous cell carcinoma or cutaneous horn, and the final diagnosis is made by the pathologist. There seems to be no gender predilection for this condition.
