Solitary nasopharyngeal metastasis from lung primary: a long-term survivor after radiotherapy.

Isolated nasopharyngeal metastasis from lung primary is a rare condition. We report a patient with stage 1B adenocarcinoma of the lung who underwent anatomical lung resection and was subsequently found to have solitary nasopharyngeal metastasis. The patient received radiotherapy to nasopharynx and remained disease-free for 10 years from the date of diagnosis of nasopharyngeal metastasis. We postulate that solitary nasopharyngeal metastasis from lung primary might be a separate entity that responded well to radiotherapy.
