Pathophysiology of Pancoast Tumor<\/h4>\n

Pancoast tumor is:<\/p>\n

1)<\/strong> caused by growth of tumor in lung apex
\n2)<\/strong> extends into eighth cervical and first and second thoracic nerves
\n3)<\/strong> can also selectively affect the cervical sympathethic nerves<\/p>\n

<\/p>\n

Signs and Symptoms<\/h4>\n

1)<\/strong> shoulder pain radiating down the arm
\n2)<\/strong> numbness in fourth and fifth fingers
\n3)<\/strong> weakness of intrinsic muscles of the hand
\n4)<\/strong> Horner’s syndrome on affected side
\n5)<\/strong> cough
\n6)<\/strong> hemoptysis
\n7)<\/strong> dyspnea
\n8)<\/strong> chest pain<\/p>\n

Characteristic Test Findings<\/h4>\n

\"pancoast<\/p>\n

Radiology<\/em> – chest radiograph shows mass in apex of lung, pleural effusion, destruction of first and second ribs<\/p>\n

Histology\/Gross Pathology<\/h4>\n

Pancoast tumor is usually squamous cell carcinoma<\/p>\n

Associated Conditions<\/h4>\n

obstructive pneumonia<\/p>\n

Treatment<\/h4>\n

1)<\/strong> preoperative radation (30 Gy in 10 treatments) followed by en bloc resection of tumor and chest wall
\n2)<\/strong> higher doses of radiation as single modality<\/p>\n

Tips for USMLE<\/h4>\n

1)<\/strong> Horner’s syndrome – ptosis (drooping) of upper eyelid, miosis (constriction of pupil), anhidrosis<\/a> (lack of sweating), and sometimes enophthalmos (depression of eyeball)
\n2)<\/strong> Pancoast tumor has a 10% cure rate with aggressive surgical resection<\/p>\n","protected":false},"excerpt":{"rendered":"
