Abstract
Merkel cell carcinoma is a rare cutaneous neuroendocrine malignancy that usually presents as a small (<2 cm) skin lesion without evidence of regional or distant disease. The diagnostic evaluation includes a chest radiograph, computed tomography of the regional lymph nodes, and positron emission tomography. Treatment consists of excision of the primary lesion and any positive regional nodes followed by postoperative radiotherapy to the primary site and regional lymphatics. The efficacy of adjuvant chemotherapy is unproven and it is not routinely employed. The 5-year local-regional control rate is approximately 80–90 %. The dominant mode of failure is distant. The 5-year cause-specific and overall survival rates are approximately 40–50 %. The likelihood of severe treatment complications is relatively low.
