title: Basaloid carcinoma of the lung presenting concurrently with cutaneous metastasis.
abstract: Basaloid carcinoma of the lung is a rarely occurring form of lung cancer morphologically resembling the basal cell carcinoma of the skin. Although various histologic types of lung cancers have metastasized to the skin, basaloid carcinoma of the lung that shows cutaneous metastasis has yet to be reported. A 48-year-old man was admitted to our pulmonology department with mild dyspnea and a solitary cutaneous mass on the left portion of his chin. Chest radiography and computed tomography of the thorax revealed an irregular infiltrative mass confined to the central portion of the left lower lobe bronchus, which is a compatible finding of primary lung cancer. Microscopically, both a cutaneous mass and fine-needle aspirate material in the lung revealed the identical findings of basaloid morphologic patterns.
