A 52-year-old man was admitted to our hospital with the complaints of chronic pain and swelling from the right shoulder to the precordial chest, which had started one month ago. He also exhibited cervical lymphadenopathy. Cervical lymph node biopsy revealed adenocarcinoma. Chest computed tomography (CT) showed a small nodule in the left upper lobe. Fluorodeoxyglucose positron emission tomography (FDG-PET) revealed multiple uptake of FDG in the right pectoralis major muscle, as well as the cervical, axillary, and thoracic lymph nodes. Based on these findings, we diagnosed the patient as having advanced lung adenocarcinoma with metastasis to the right pectoralis major muscle. The patient was treated with bevacizumab combination chemotherapy, which induced tumor regression and improved the symptoms. This is a rare case in which bevacizumab combination chemotherapy proved effective for lung adenocarcinoma metastasis to the skeletal muscles.
