Papillary lesions of the nasal cavity and paranasal sinuses. Part II: Inverting papillomas. A study of 29 cases

Inverted papilloma of paranasal sinuses

“…The frequency of recurrence after surgical removal is reported as 28-74% (Alford and Winship, 1963;Norris, 1963;Hyams, 1971;Snyder and Perzin, 1972;Batsakis, 1987;Ganzer et al, 1992). The observation that IP tends to recur after incomplete surgical removal supports investigations suggesting that IP is a true neoplasm arising from a single progenitor cell and that recurrence represents growth of the residual clone (Califano et al, 2000).…”

“…Ringertz (1938) recognized the characteristic endophytic growth pattern and coined the term 'inverting papilloma'. Synonyms for the same entity were 'genuine papilloma of the nasal cavity' (Kramer and Som, 1935), 'inverting papilloma' (Norris, 1963), and 'inverted papilloma' (Fechner and Alford, 1968;Hyams, 1971). Berendes (1966) noted the tendency towards destructive growth, recurrence, and epithelial metaplasia and named it 'malignant papilloma'.…”

Nasal Endoscope: An Armamentarium in the Management of Sinonasal Inverted Papilloma

“…Malignancy was noted predominantly in men and increased with increasing age [21,28,30,31]. Reported recurrence rate after exculsive endoscopic removal was 28-74 % [7,9,12,32]. Krouse's [23] reviewed published data of 30 years on 1426 patients of Inverted Papilloma and found recurrence rate of 18 % after aggressive open surgery (lateral rhinotomy, midface degloving, maxillectomy) and the recurrence rates of 11.8 % after endoscopic surgery.…”

“…This emphasizes the need of endoscopy in clearing the disease even in the open surgical approach. The advantage of using endoscopy is well established in the previous studies in the management of SIP [7,9,12,23,[32][33][34][35][36][37][38].…”

“…The characteristic endophytic growth pattern and the term 'inverting papilloma' was coined by Ringertz in1938 [4]. It has many synonyms e.g., 'genuine papilloma of the nasal cavity' [5,6], 'inverting papilloma' [7], and 'inverted papilloma' [8,9], epithelial papilloma, fungiform papilloma, transitional cell papilloma, squamous cell papilloma, papillary sinusitis, soft papilloma, cylindrical cell carcinoma, polyp with inverting metaplasia, Ewing's papilloma and benign transitional cell growth. Vrabec suggested the term 'inverted Schneiderian papilloma' as these tumours originated from schneiderian membrane, which was derived from ectoderm of nasal placode [10].…”
