Quizplus · Accepted Answer

Pancoast's tumor, typically a form of lung cancer located at the top of the lung, can cause a range of symptoms due to its location near various nerves and structures. Recognized features include ipsilateral Horner's syndrome (A), wasting of the dorsal interossei muscles (B), and pain radiating to the fourth and fifth fingers (C), which are related to the tumor's impact on the brachial plexus and sympathetic ganglion. Erosion of the first rib (D) can occur due to the tumor's proximity and direct invasion. However, weakness of abduction at the shoulder (E) is not a recognized feature of Pancoast's tumor, as this action primarily involves the deltoid muscle, which is not directly affected by the tumor's typical location and impact on the brachial plexus.
