Endobronchial melanoma metastasis 40 years after the excision of the primary cutaneous tumor: A case report.

Rationale: Endobronchial melanoma metastases are rare, comprising 4.5% of all endobronchial metastases. They are diagnosed at a median time of 48 months from primary tumor presentation, and survival of these patients is poorer when accompanied by other metastatic sites or malignant pleural effusion.
