In this article, we present a 75-year-old male with worsened nasal obstruction on the left side. Nasal endoscopy revealed bilateral grade 2 nasal polyps and a large polyp in the left posterior choana. postnasal space could not be viewed. Urgent computed tomography and magnetic resonance imaging revealed a lesion in the postnasal space. The patient was scheduled for endoscopic excision of the postnasal space lesion and bilateral nasal polypectomy. Histopathological examination of the samples revealed benign nature of polyps and plasmacytoma for postnasal space lesion. The patient is still on radiotherapy.
