[A case of Merkel carcinoma with facial localization]

A case of Merkel carcinoma is reported. It concerns a 40-year-old lady, who had first noticed the lesion one year before she came to our observation. The authors point out the rarity of this tumour, whose not distinctive gross appearance (firm, sessile tumour with well circumscribed margins; hyperhemic overlaying skin; slowly increasing volume) may suggest other macroscopic diagnoses such as intradermal nevus or nodular basalioma. The authors also point out the usefulness of a prompt correct clinical diagnosis of this lesion, whose clinical behaviour may be highly aggressive.
