[Merkel cell carcinoma of the skin. Two clinical cases]

In this study are described two clinical cases of Merkel cell tumor treated in the first half of 1991. The MCC is a rare primary skin tumor with an aggressive biologic nature. The elective therapy of primary sites is surgical management with lymphadenectomy although this kind of treatment is debated. Local recurrence high incidence requires a frequent and careful follow-up with possibility of second surgical treatment in the cases without metastasis and a radiochemotherapy in the patients affected by systemic recurrences.
