This case involves a fifty-two-year-old male patient. He had a history of progressive left nasal obstruction and foreign body sensation that developed acutely. The patient underwent several endoscopic procedures to evaluate for possible obstruction. An endonasal excision of a left nasal polyp was conducted and a sample was sent to pathology for evaluation. For eleven months, the patient did not receive a follow-up and, during that time, a small mass went unrecognized and untreated. A year after the original presentation, the mass was finally resected, but the pathology reports showed that irregular margins were present and the mass fully invaded surrounding tissue. By the time the mass was identified and resected, the patient had developed metastatic squamous cell carcinoma.
