The Pancoast tumor is an uncommon type of lung cancer that arises from within the superior sulcus. With most clinical manifestations occurring due to mass effect, Pancoast syndrome is a known complication that includes shoulder and arm musculoskeletal pain, Horner's syndrome and neurological complications of the upper extremities, including weakness and atrophy. Even though adenocarcinoma is the most common cause of Pancoast syndrome among lung cancers, other malignancies can be responsible as well. Treatment is similar to that of other standard NSCLC treatments that include chemotherapy, radiation, immunotherapy and surgery. Here we report a patient with Pancoast syndrome secondary to a poorly differentiated malignant neoplasm composed of anaplastic cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
