A 70-year-old man presented with three enlarging, painless skin masses on his scalp and right forearm for more than one month. Physical examination showed a 2 cm and 1.2 cm in diameter, flesh-colored, round, firm nodules with slightly ulcerated surface on the scalp, and a 1.2 cm nodule with the similar morphology on the skin of the right forearm. Histopathological examination revealed a metastatic poorly differentiated squamous cell carcinoma. He was a heavy smoker with a history of lung cancer. that was proven as a poorly-differentiated squamous cell carcinoma in the left upper lung. Based on the history and the similarity of the histologic features between the primary lesion and the cutaneous metastatic lesion, the diagnosis of cutaneous metastasis from lung cancer was made. The patient died one month later.
