Abstract:
Axillary lymph node metastasis (ALNM) is a rare mode of lung cancer (LC) metastasis. We present two LC cases with ALNM, including one case of sarcomatoid carcinoma and one of squamous cell carcinoma. Both cases were diagnosed by positron emission tomography-computed tomography and needle biopsy. A literature review indicates that the most likely route for ALNM from LC is through retrograde diffusion of supraclavicular lymph nodes.
