“…The histomorphologically based classification formulated by Hyams (1971) [21, 22] divided these polyps (papillomas of the sinonasal tract) due to their pattern of growth into three histological categories and their malignant counterparts [21, 23], and they are classified as follows (see Table 1): fungiform (everted) papillomas (septal papilloma) (50%): arise from the nasal septum and have an exophytic growth pattern, oncocytic Schneiderian papillomas : formerly known as “cylindrical cell papillomas , ” arise from the lateral sinus wall or paranasal sinuses, and lined with a distinctive stratified lining of bright pink granular columnar cells with microcysts, and more often mixed with typical inverted papilloma, rather than presenting in its pure form [24–34], inverted papillomas: arise from the lateral nasal or sinus wall or paranasal sinuses and show an endophytic or mixed exophytic/endophytic growth pattern [35]. …”

Skull Base Inverted Papilloma: A Comprehensive Review

Skull base inverted papilloma (IP) is an unusual entity for many neurosurgeons. IP is renowned for its high rate of recurrence, its ability to cause local destruction, and its association with malignancy. This paper is a comprehensive review of the reports, studies, and reviews published in the current biomedical literature from 1947 to September 2010 and synthesize this information to focus on its potential invasion to the base of the skull and possible intradural extension. The objective is to familiarize the clinician with the different aspects of this unusual disease. The role of modern diagnostic tools in medical imaging in order to assess clearly the limits of the tumors and to enhance the efficiency and the safety in the choice of a surgical approach is pointed out. The treatment guidelines for IP have undergone a complex evolution that continues today. Radical excision of the tumour is technically difficult and often incomplete. Successful management of IP requires resection of the affected mucosa which could be achieved with open surgery, endoscopic, or combined approach. Radio and chemotherapy were used for certain indications. More optimally research would be a multicenter randomized trials with large size cohorts.

“…A previous study demonstrated a similar rate of recurrence and malignant changes between OSP and IP. 4 However, Yang et al reported a higher incidence of malignant changes associated with OSP (10% -17%) compared with IP (5%-10%). 5 Endoscopic surgical extirpation has been the treatment of choice for OSP.…”

“…5 Endoscopic surgical extirpation has been the treatment of choice for OSP. 3,4 A previous study reported a local OSP recurrence of 33% to 40%. 6 However, Karligkiotis et al documented a mere 6% recurrence (2 out of 33 patients) through an endoscopic approach.…”

A 66-year-old man visited the ophthalmology department due to epiphora and was subsequently diagnosed with oncocytic schneiderian papilloma. Surgical removal was recommended to the patient; however, he refused this option. Therefore, a radiation of 64 gray (Gy) was administered in 32 daily doses (2 Gy daily) over 45 days using intensity-modulated radiotherapy. Four months after radiotherapy, the tumor had disappeared. Two years postradiotherapy, the patient was healthy, without tumor recurrence or the development of orbital complications. The authors suggest that radiotherapy could be an adjuvant or definite treatment modality for patients of oncocytic schneiderian papilloma unsuitable for complete surgical removal, or those associated with a high risk of surgery-related complications.
