Skin lesion is a bumpy painless nodule, with size less than 2 cm. Skin surface is red or purple. Merkel cell carcinoma develops faster and spread easily. Approximately 50% of patients have lymph node metastasis within 1-2 years. 35% patients have distant metastases. Liver, lung and skin metastases are the most common. Treatment: During the early stage, local excision combined with radiotherapy. If there is recurrence or regional lymph node metastasis, expand the excision scope, combined with radiotherapy and chemotherapy.
