A Complete Ultrathin Bronchoscopy Blackout.

Ultrathin bronchoscopy (UTB) is increasingly being used in solitary pulmonary nodule (SPN) diagnostics. The increasing capabilities of the bronchoscope in reaching peripheral regions of the lungs have allowed us to examine and understand the bronchoscopic appearance of previously inaccessible SPNs. Melanoma is a tumor produced by the malignant transformation of melanocytes, usually in the skin, and is the most aggressive form of skin cancer with a low survival rate in patients with metastatic disease. The most common site of metastases is the lungs, affecting up to 30% of patients.1
