“…Endoscopic removal can be performed on selected lesions with a recurrence rate of 12% compared to that of more aggressive techniques of 18% (33). Pasquini et al compared traditional and endoscopic methods in 89 cases with a follow-up period of 96 months and 54 months, respectively (94). They reported a lower recurrence rate of 3% and a mean hospital stay of 1 day with endoscopic approaches compared to a 24% recurrence rate and 5 days hospitalization with traditional methods.…”

Abstract. Inverted papilloma (IP) is a benign sinonasal lesion that has a known propensity for recurrence, local aggressiveness and an association with transformation to squamous cell carcinoma. Due to the high rate of recurrence, association with malignancy and a tendency of multicentricity, the surgical approaches to treatment are controversial. Over the years there has been a slow evolution from aggressive (en bloc) resection by lateral rhinotomy to endoscopic techniques. This progress corresponds to the advances that have been made in endoscopic sinus surgery over the past 15 years. Technological advances have allowed the detection of sinonasal IP before its extension beyond the sinonasal region, thus enabling minimally invasive techniques to be used in the treatment of selected cases of IP. Differences in recurrence rates were not observed for endoscopic management as compared with lateral rhinotomy or sublabial degloving approaches. In terms of aetiology there is certain evidence that the presence of HPV in IP could be predictive of malignant transformation. Although IPs are monoclonal proliferations, they do not fit the profile of a prototypic precursor lesion. In contrast, an increased EGFR and TGF-· expression is associated with early events in IP carcinogenesis. Parameters such as hyperkeratosis, squamous epithelial hyperplasia and a high mitotic index are negative prognostic indicators, which could be useful in the future follow-up of patients with IP. Present literature should encourage us to recommend the use of a uniformly accepted staging system. The propensity for delayed recurrences and the maximal 13% incidence of malignant transformation mandates careful, long-term follow-up.

“…[6][7][8] Preoperative evaluation by using cross-sectional imaging, such as CT and MR imaging, is essential for the selection of surgical options by correctly identifying the location and extent of the tumor, and postoperative follow-up examinations at regular intervals are also highly recommended for the early detection of the recurrent disease. [11][12][13][14][15][16][17][18][22][23][24] However, differentiation of IP from other malignant sinonasal tumors by analyzing the internal characteristics on radiologic imaging is often difficult, because there is a significant overlap between those diseases. 15,16,19 IP is seen pathologically as a vascular mass with prominent mucous cyst inclusions interspersed throughout the epithelium and a high intracellular glycogen content.…”

“…1,2 Although benign, it has a known propensity for a high rate of recurrence, local aggressiveness, multicentricity, and association with synchronous or metachronous squamous cell carcinoma (SCC). [3][4][5][6][7][8][9][10][11][12] Although CT and MR imaging are useful for preoperative assessment of sinonasal IP, differentiation of IP from other malignant sinonasal tumors is often difficult because of a significant overlap of the imaging features. [13][14][15][16][17][18][19] Barnes et al 20 described a distinctive gross mucosal morphology of IP, a so-called convoluted cerebriform pattern (CCP), which can be reflected on MR imaging by the characteristic alternating hypointense and hyperintense bands on T2-weighted and contrast-enhanced T1-weighted images, as reported by Ojiri et al 17 and supported by Maroldi et al 19 years later.…”

“…Additionally, unilateral epistaxis-as was seen in our patient-was more frequently associated with neoplastic disease than benign causes such as chronic rhinosinusitis and nasal polyposis in that particular study population [17]. The existing literature on unilateral sinusitis and its association with underlying malignancy is limited and primarily focused on inverted papilloma, which has a rate of malignant degeneration to squamous cell carcinoma of between 3.4% [18] and 9.7% [19]. The majority of other studies in this area focus specifically on unilateral maxillary sinusitis secondary to odontogenic sources.…”

Rhabdomyosarcoma of the Paranasal Sinuses Initially Diagnosed as Acute Sinusitis

et al. 2017

Rhabdomyosarcoma (RMS) is an uncommon soft tissue malignancy that is typically found in the pediatric population. Here we describe a rare case of widely metastatic alveolar RMS of the right paranasal sinuses in an adult woman who presented with several months of unilateral sinus symptoms that was initially misdiagnosed as acute sinusitis. A middle-aged female presented with two months of right sinus pressure and unilateral epistaxis. She had previously been diagnosed with acute sinusitis and was treated with antibiotics without improvement. Nasal endoscopy demonstrated a fungating right nasal cavity mass. On computed tomography scan (CT), she was found to have metastatic disease in the mediastinum, lungs, bones, pancreas, and right ovary. Pathology of the nasal cavity mass was consistent with alveolar RMS. The patient initially responded well to chemotherapy, but subsequently developed brain and leptomeningeal metastases. This case of sinonasal rhabdomyosarcoma is unique in the extent of metastatic disease at the time of diagnosis and the initial misdiagnosis despite concerning unilateral symptoms and imaging. This thus highlights the importance of maintaining a high index of suspicion for malignancy in patients with unilateral sinus symptoms.
