Bilateral antrochoanal polyp: report of a new case and systematic review of the literature

Abstract

Antrochonal polyp (ACP) is a benign, rare, and generally unilateral tumor which originates from the maxillary sinus mucosa. Bilateral ACP is extremely rare. Only few cases have been documented in the literature until 2018. The authors report the case of a 44-year-old women, who presented with a bilateral progressive nasal obstruction for the past 2 years, slight headache and a decreased sense of smell has been started in last four months. Nasal endoscopy revealed pale polypoidal masses in nasal cavities, arising from each middle meatus and extending to the nasopharynx. Computed tomography of the paranasal sinuses revealed the presence of soft-tissue masses in the maxillary sinuses, passing through the maxillary ostium, and extending into the corresponding nasal cavities, and posteriorly upto the nasopharynx. The other sinuses were normally aerated. The tumors were removed surgically with a nasal endoscopy technique. Histopathology examination the two lesions revealed benign inflammatory nasal polyps.

“…It was observed that all cases operated in our clinic between the years 2012 and 2016 due to anthrocoanal polyp were unilateral. It has been reported that an anthrocoanal polyp is more common in men and under 20 years of age (10,12). The results of our study show that anthrochoanal polyp is seen 2 times more common in men.…”

“…Antrochoanal polyps frequently present as a unilateral nasal mass. Very few articles in the literature have reported bilateral involvement (12,13,14).…”

“…Bilateral forms are very rare [1][2][3][4][5][6][7]. Only 14 cases have been mentioned in the literature [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Diagnosis difficulty is generally due to the scarcity of this disease, and the similar clinical presentation of more frequent differential diagnosis [1][2][3][4].…”

“…Diagnosis difficulty is generally due to the scarcity of this disease, and the similar clinical presentation of more frequent differential diagnosis [1][2][3][4]. Management is generally surgical through functional endoscopic sinus surgery, and outcome is great with clinical improvement and no recurrence in follow-up [8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”
