A Pancoast tumor is a cancer that begins in the upper part of the lung.[2] It often spreads to nearby tissues such as the ribs and vertebrae.[2] Symptoms on the affected side may include shoulder pain, arm numbness, large pupil, dropping of the upper eyelid, and shinkage of muscles in the hand.[1] Later in the course of the disease shortness of breath may occur.[1]
More than 95% of Pancoast tumors are non-small cell lung cancers, with most of the rest being small cell lung cancer.[1] Uncommonly it may occur as a result of thyroid cancer, lymphoma, or metastasis.[1] An upper lung abscess may also cause similar symptoms.[1] The underlying mechanism involves compression or invasion of structures in the area.[1] Diagnosis is by medical imaging and tissue biopsy.[1]
Treatment generally involves chemotherapy, radiation therapy, and surgery.[1] Pancoast tumors represent about 4% of lung cancers.[1] It was first described in 1838 by Edward Hare and is named after Henry Pancoast, an American radiologist, who described the condition in 1924.[3]
