Rare primary malignant melanoma of the lung

Primary malignant melanoma of the lung is a very rare but very aggressive tumour. We report two patients who had primary malignant melanoma of the lung and underwent surgical resection in our hospital. Both of them had lymph node metastases and received postoperative adjuvant therapy. They died of tumour recurrence in 12 and 37 months. Management of this uncommon tumour is difficult and has not been standardized, but surgical resection is the only treatment option.
