Final answer:
The symptoms described align with Horner's syndrome, which can be a consequence of a lung mass such as a Pancoast tumor pressing on sympathetic nerves. It is characterized by ptosis, miosis, and anhidrosis on one side of the face. The presence of these symptoms alongside typical lung cancer signs such as cough and chest pain is clinically significant.
Step-by-step explanation:
The symptoms of lung mass, unilateral ptosis, miosis, and anhidrosis you've described are associated with Horner's syndrome, which can occur when a lung tumor affects certain nerves. The correct symptoms from your options would be 2) Drooping of one eyelid, constricted pupil, decreased sweating on one side of the face. These symptoms are indicative of disturbances in the autonomic nerve supply, commonly due to the involvement of the sympathetic chain, which may be compressed or invaded by a lung mass such as a Pancoast tumor situated at the apex of the lung.
Lung cancer itself can present with distinctive symptoms like cough, shortness of breath, chest pain, and in advanced stages, symptoms like weight loss, excessive sweating, and fatigue may be observed. Horner's syndrome alongside these symptoms can hint at the presence of a tumor in the thoracic cavity causing pressure on the sympathetic nerve supply, particularly the cervical sympathetic chain that innervates the face and eyes.
