The high propensity to recur, local aggressive behavior and possibility of malignant transformation attract considerable interest. <strong>Objective:</strong> To assess the factors affecting Sino-nasal IP, malignant transformation rate, and post-operative recurrence rate. <strong>Methods:</strong> A retrospective study was carried out on all cases diagnosed as Sino-Nasal Papilloma between January 2010 and December 2020 at Salmaniya Medical Complex, Bahrain. Data gathered from medical records were analyzed using SPSS. A total of 49 Sino-Nasal Papilloma cases were recorded of which 37 were IP. Factors affecting Sino-Nasal IPs are presented. <strong>Results:</strong> Sino-Nasal IP was recorded in 37 cases, composed of 28 males and 9 females with first presentation average age of 45.86 years. These involved 20 cases in the left side, 14 in the right side and 3 were bilateral. Recurrence in males and females was found to be 35.7% and 33%, respectively, with an average of 12.6 months. The symptoms include nasal blockage (97.3%), epistaxis and postnasal drip (13.5% each), headache (8.1%) and hyposmia and rhinorrhea (5.4%, each). The main recurrence was at stage T2 (60.5%), while in smokers (26.7%) and non-smokers (50%). Malignant transformation occurred in one patient only (2.6%). <strong>Conclusion:</strong> IP is the most common type of SNP with male predominance. The recurrence rate is high with an average of a year and the malignant transformation occurred in 2.6 % of the cases.展开更多

We reported a case of sino-nasal malignant melanoma in a 46-year-old Asian lady who presented with epistaxis and dysphagia. By nasoendoscopy and CT scan imaging, the diagnosis of sino-nasal malignant melanoma was later confirmed by histopathology examination along with immunohistochemistry by using Melan A and S100. Malignant melanoma in the head and neck is rare and has a poor prognosis. There has been an increase in the incidence of 5% per year and mortality at 2% per year. This dictates malignant melanoma has rapidly increased compared to any other cancer except lung cancer in women and has contributed to the third highest number of deaths among all cancers. The mortality rate has also increased, and that is attributed to the negligence of symptoms during the initial period. This usually leads to patients seeking consultation during the advanced stage of the disease. In conclusion, this paper is to report that malignant melanoma may be one of the differentials of sino-nasal masses, and it may mimic nasopharyngeal carcinoma in its presentation.展开更多

Evidences have shown that antrochoanal polyp often times coexists with adenoid enlargement especially in the young which was in sharp contrast to ethmoidal polyposis occurring in the presence of adenoid enlargement. Moreover, the hidden location of nasopharynx housing the adenoids, coupled with the masking effect of bilateral sinonasal polyps, leads to inadvertent misdiagnosis of this complex pathology with subsequent difficulty in providing effective management. Case Presentation: A 24 year-old lady presented with recurrent bilateral nasal obstruction that became persistent associated with nasal discharge and anosmia. She also had recurrent right otorrhoea with associated hearing loss. Diagnostic rigid nasal endoscopy revealed mucoid discharge with bilateral polypoid masses filling both nasal cavities. Otoendoscopic finding revealed a small (about 5%) central tympanic membrane perforation. A clinical assessment of chronic rhinosinusitis with nasal polyposis complicated by chronic suppurative otitis media (CSOM) was made. A non-contrast CT scan of the paranasal sinuses showed isodense lesions in the nasal cavities, all paranasal sinuses and the entire nasopharynx. She had endoscopic sinus surgery and a nasopharyngeal clearance biopsy. The nasal, paranasal and nasopharyngeal masses had histologic confirmation of inflammatory nasal polyps and lymphoid (adenoid) hyperplasia respectively. Her condition improved remarkably with subsequent medical treatment. She was followed up for 8 months and no recurrence was observed. Conclusion: Sinonasal polyposis can coexist with adenoid hypertrophy and middle ear disease as a single pathological condition. Hence, a high index of suspicion and thorough evaluation become necessary for making timely diagnoses and instituting effective management.展开更多

A 75-year-old woman presented with chronic persistent left nasal obstruction and gradual painless non-axial proptosis with loss of vision in the left eye. Computed tomography scan showed an iso-dense lesion filling the frontal, left ethmoidal and sphenoidal sinuses, and the nasal cavity, with extension into the left orbit. She underwent surgical tumor resection with orbital exenteration and histology revealed features of an aggressive hyperkeratotic squamous papilloma arising from the sino-nasal region. Although squamous papillomas have been natively associated with the oral cavity and oropharynx, they present less frequently as sino-nasal tumors with orbital invasion.展开更多

However, it is often requested by non experienced practitioners. We aimed to describe the utility and the appropriateness of CT Scan request forms and results in the diagnosis of SN pathologies. <strong>Method:</strong> We conducted a retrospective cross-sectional study in four health facilities in Yaoundé, Cameroun, from October 2018 to September 2019. All patients to whom SN CT Scan was performed were called for an appointment. After informed consent, data on the appropriateness and conformity of the request form were collected and compared to the guidelines of the French society of radiology. CT Scan results were also collected and the quality of the report was evaluated. <strong>Results:</strong> A total of 206 SN CT Scan request forms and reports were included, with a mean patient age of 37.7 ± 16.1 years. The request form was conformed to guidelines in 8.3% of cases and was found appropriate in 62.6% of cases. No CT Scan report had all the items required, and 159 (77.2%) reports were useful. The most common diagnosis in patients with abnormal results was chronic sinusitis (49.5%) and SN polyp or polyposis (19.4%). <strong>Conclusion:</strong> Most of SN CT Scan requested were appropriate and useful. However, the conformity of request forms and reports to the guidelines is low. Suggesting the need for capacity building for the diagnosis of SN pathologies especially for non specialists like general practitioners and nurses.展开更多
