“…Few previously reported cases originated from the inferior turbinate, 9 , 10 , 11 , 12 but Caylakli et al reported cavernous hemangioma in the middle turbinate, 13 Nakahira et al reported in vomer, 14 Graumüller et al demonstrated a case in lamina perpendicular is ossi ethmoidalis, 15 Engels et al reported a case in the sinus maxillaris, 16 and recently Yeon et al published a case report on the lateral wall of the inferior nasal meatus. 17 Extremely rare conditions are seen in patients with concomitant malformation or benign or malignant lesions in the sinonasal sinus anatomical site. Our patient had a history of progressive right and left‐sided nasal obstruction without a history of excessive bleeding and experienced endoscopic sinus surgery removing polypoidal masses from both sides with quite excessive intraoperative bleeding from the right side that has been proven to be a cavernous hemangioma, whereas the left side polyp was proven to be an inverted papilloma.…”
