In nasopharyngeal carcinoma, which presenting symptoms are commonly observed?

• A. Severe neck pain and seizures
• B. Nasal congestion and epistaxis
• C. Facial swelling and loss of smell
• D. Chronic cough and hoarseness

Answer: (B)

In nasopharyngeal carcinoma, the commonly observed presenting symptoms include nasal congestion and epistaxis. This type of cancer often arises in the nasopharynx, which is located behind the nose and above the back of the throat. As it develops, individuals may experience nasal obstruction due to tumor growth, leading to a sensation of congestion. Moreover, the tumor may invade local blood vessels, resulting in frequent nosebleeds, or epistaxis. These symptoms are particularly salient because they directly relate to the cancer's location, affecting normal nasal and pharyngeal function.

The other symptoms presented in the other options, while they may occur in various other conditions or cancers, are not typical for nasopharyngeal carcinoma. Severe neck pain and seizures tend to suggest more advanced disease or invasion of surrounding structures rather than primary presenting symptoms. Facial swelling and loss of smell can occur but are not as specific to nasopharyngeal carcinoma; they might instead suggest other nasal or sinus conditions. Chronic cough and hoarseness may be associated with other upper respiratory or thoracic issues, rather than being classic presenting symptoms for this particular type of cancer.
