This unique presentation often leads to delayed diagnosis and misdiagnosis as orthopedic or neurological problems. Key Differences: Location and Invasion: Pancoast tumors: Grow in the upper part of the lung (apex), above the first rib, and extend outward to directly invade surrounding structures like the brachial plexus (nerves), subclavian vessels, ribs, and vertebrae. Other Lung Carcinomas: More commonly occur in the central or peripheral parts of the lungs, away from the thoracic inlet. Symptoms: Pancoast tumors: Characterized by Pancoast-Tobias syndrome, which includes severe shoulder and arm pain radiating to the hand, and Horner's syndrome (drooping eyelid, constricted pupil, reduced sweating). Other Lung Carcinomas: More likely to present with classic symptoms such as persistent cough, shortness of breath (dyspnea), coughing up blood (hemoptysis), and chest pain, especially in the early stages. Diagnostic Challenge: Pancoast tumors: The absence of typical lung symptoms and the presence of pain often lead to misdiagnosis as musculoskeletal or neurological issues, delaying cancer detection. Other Lung Carcinomas: Symptoms are more directly related to the lungs, allowing for earlier diagnosis through standard methods like bronchoscopy. Tumor Growth Pattern: Pancoast tumors: Their large, peripheral, and plaquelike extension is a key feature, affecting the chest wall more than the underlying lung parenchyma. Other Lung Carcinomas: Tend to originate in the lung and may spread to the lymph nodes or distant organs, but do not necessarily invade the apical chest wall directly. --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to the perks: Sign up now on our website at https://members.drnajeeblectures.com/ Follow us on Facebook:-   / drnajeeb   Follow us on Instagram:-   / drnajeeblectures
