A patient presents with pain in the pharyngeal area and has been diagnosed with nasopharyngeal carcinoma. What is the most likely diagnosis?

Explanation

The symptoms of pharyngeal pain in a patient with nasopharyngeal carcinoma are most commonly associated with Horner's syndrome, which results from sympathetic nerve involvement. Glossopharyngeal neuralgia, Trotter's syndrome, and Eagle's syndrome present with different clinical features and are less likely in this context.
