We present the case of a 64-year-old male patient who reported right shoulder radiculopathy, right-hand weakness, and 3 kg weight loss. Physical examination revealed restricted active shoulder mobility. Magnetic resonance imaging showed a massive septated lesion in the glenoid that infiltrated adjacent tissues, indicating sarcoma. Core needle biopsy revealed metastatic poorly differentiated squamous cell cancer. Positron emission tomography scan results showed a primary lung tumor (stage IVB) with metastases to the left adrenal gland and a large mass in the right glenoid. This case describes the first documented case of metastatic lung squamous cell carcinoma to the shoulder glenoid, an uncommon metastatic location.
