Sinonasal Angiomatous Polyp a subtype of sinonasal polyp, is a benign and non-neoplastic lesion rarely reported in the literature. We recently came across a middle aged female who presented to us with right sided nasal blockage with episodic bleeding for 6 months. On nasal endoscopy polypoidal nasal mass was seen occupying the nasal cavity, maxillary sinus and the nasopharyngeal region with bleeding areas. Histopathology confirmed to be as Sinonasal Angiomatous polyp. Here, we are discussing the presentations of the sinonasal angiomatous polyp, its diagnosis and the line of management for the patient.
