A pancoast tumor, or superior sulcus tumor, is a tumor of the pulmonary apex i.e. a type of lung cancer defined primarily by its location situated at the top end of either the right or left lung. The growing tumor can cause compression of a brachiocephalic vein, subclavian artery, phrenic nerve, recurrent laryngeal nerve, vagus nerve, or, characteristically, compression of a sympathetic ganglion resulting in a range of symptoms known as Horner''s syndrome.

A pancoast tumor, or superior sulcus tumor, is a tumor of the pulmonary apex i.e. a type of lung cancer defined primarily by its location situated at the top end of either the right or left lung. The growing tumor can cause compression of a brachiocephalic vein, subclavian artery, phrenic nerve, recurrent laryngeal nerve, vagus nerve, or, characteristically, compression of a sympathetic ganglion resulting in a range of symptoms known as Horner''s syndrome. Pancoast tumors are named for Henry Pancoast, a US radiologist, who described them in 1924 and 1932. Aside from cancer general symptoms such as malaise, fever, weight loss and fatigue, pancoast tumor can include a complete Horner''s syndrome in severe cases: miosis (constriction of the pupils), anhidrosis (lack of sweating), ptosis (drooping of the eyelid) and enophthalmos (sunken eyeball). In progressive cases, the brachial plexus is also affected, causing pain and weakness in the muscles of the arm and hand. The tumor can also compress the right recurrent laryngeal nerve, and from this a hoarse voice and bovine cough may occur.
