Step-by-step explanation:
Definition of Pancoast Syndrome
Pancoast syndrome is a condition characterized by a group of symptoms that result from a Pancoast tumor, which is a type of lung cancer that occurs at the top of the lung. The tumors in this location can invade nearby tissues such as the ribs and spine, as well as affect the sympathetic nervous system, leading to a unique set of symptoms. Among these symptoms include severe shoulder pain, Horner's syndrome (which consists of drooping eyelid, smaller pupil size, and lack of perspiration on one side of the face), and weakness or atrophy of hand muscles. Management and prognosis of Pancoast syndrome depend on the stage of the tumor and the overall health of the individual. Early diagnosis and treatment are crucial for better outcomes. Treatments may involve surgery, radiation therapy, and chemotherapy.
