PURPOSE: To determine the histological distribution and trends in incidence of sinonasal malignancies in Jamaica. METHODS: Cases of all sinonasal malignancies diagnosed between 1973 and 2007 were extracted from the archives of the Jamaica Cancer Registry. Data recorded for each case included age at diagnosis, sex, year of diagnosis, topography, and histology. Data were used to calculate frequencies, age-specific incidence rates, and age-standardized incidence rates (ASRs)...

Misdiagnosis of respiratory epithelial adenomatoid hamartomas for malignant tumors can lead to an aggressive surgical procedure, which is not necessary in the case of a respiratory epithelial adenomatoid hamartoma. Detailed analysis of sinonasal CT scans without contrast can help to distinguish respiratory epithelial adenomatoid hamartomas of the olfactory cleft from small malignant tumors (T1 and T2) of the olfactory clefts. Criteria in favor of diagnosis of small malignant tumors of the olfactory clefts on CT scans without contrast were unilaterality of masses in the olfactory clefts, large olfactory clefts /small olfactory clefts ratio ≥ 2 (sensibility at 91% and specificity at 100%), and presence of bone erosion...

The nasal cavity and paranasal sinuses are covered with ciliated respiratory mucosa of ectodermal origin, known as Schneiderian epithelium, which can give rise to different types of sinonasal carcinomas. A 42-year-old woman with a history of nasal polypectomy 3 years previously presented with nasal obstruction and rhinorrhea. She was found to have a papillary mass involving the left nasal cavity, and the left maxillary and ethmoidal sinuses by radiologic examination. She underwent endonasal resection under the diagnosis of oncocytic papilloma...

BACKGROUND: Sinonasal teratocarcinosarcoma is a rare and aggressive malignancy with histological features of both carcinosarcoma and teratoma. The optimal management of this malignancy is unclear, with most patients being managed by a combination of surgery and radiotherapy. CASE PRESENTATION: We describe an 83-year-old white woman with sinonasal teratocarcinosarcoma of her left nasal cavity treated with surgical debulking initially with radiological evidence of residual disease which was treated with radiotherapy (60 Gy in 30 fractions)...

Papillomas are uncommon tumors of the sinonasal tract histologically derived from the Schneiderian membrane. Three distinctive variants are described, the exophytic, the inverting and the oncocytic types. On physical examination, their appearance varies from exophytic-fungiform seen in the exophytic variant, to polypoid-papillary in both the inverting and oncocytic variant. The presence of an asymptomatic mass or epistaxis and unilateral nasal obstruction are the typical presenting symptoms. Clinically they tend to recur and, although benign, they may erode the bone laminas by pressure, especially the inverting type, causing proptosis and other co-morbidities...

BACKGROUND: Chronic rhinosinusitis with and without nasal polyps (CRSw/sNP) are common conditions decreasing health-related quality of life (HRQOL). Individual symptoms capable of predicting outcome after endoscopic sinus surgery (ESS) are poorly defined, and the indirect costs of CRS is rarely reported in Europe. METHODOLOGY: Patients with CRSw/sNP admitted for ESS were prospectively enrolled. Patients completed the 22 Sinonasal Outcome Test (SNOT-22), the short-form 36-item questionnaire (SF-36), a Visual Analogue Scale (VAS) and reported CRS-related absenteeism pre- and post-operatively...

NKX2.2 is a new immunohistochemical marker that has been reported to be sensitive and specific for Ewing sarcoma (ES). It has not, however, been investigated specifically in the sinonasal small round blue cell tumor (SRBCT) differential diagnosis which includes many tumors specific to that site. It has also not been investigated in the newly recognized "adamantinoma-like" variant of ES. Immunohistochemistry for NKX2.2 was performed on 170 poorly differentiated sinonasal neoplasms: 73 squamous cell carcinomas (67 poorly differentiated, non-keratinizing, or basaloid types and 6 nasopharyngeal carcinomas), 46 olfactory neuroblastomas, 8 sinonasal undifferentiated carcinomas (SNUCs), 6 melanomas, 7 Ewing sarcomas, 6 SMARCB1-deficient carcinomas, 6 teratocarcinosarcomas, 5 alveolar rhabdomyosarcomas, 4 solid adenoid cystic carcinomas, 4 NK/T cell lymphomas, 3 NUT carcinomas, and 2 small cell carcinomas...

BACKGROUND: Fungal sinusitis is increasing worldwide in the past two decades. It is divided into two types including invasive and noninvasive. Noninvasive types contain allergic fungal sinusitis (AFS) and fungus ball. AFS is a hypersensitivity reaction to fungal allergens in the mucosa of the sinonasal tract in atopic individuals. The fungus ball is a different type of noninvasive fungal rhinosinusitis which is delineated as an accumulation of debris and fungal elements inside a paranasal sinus...

BACKGROUND: Endoscopic sinus surgery poses unique training challenges due to complex and variable anatomy, and the risk of major complications. We sought to create and provide validity evidence for a novel 3D-printed simulator of the nose and paranasal sinuses. METHODS: Sinonasal computed tomography (CT) images of a patient were imported into 3D visualization software. Segmentation of bony and soft tissue structures was then performed. The model was printed using simulated bone and soft tissue materials...

Phosphaturic mesenchymal tumor (PMT) is a rare neoplasm of uncertain histogenesis that has been linked to tumor-induced osteomalacia (TIO) since 1959. The neoplastic cells produce increased amount of FGF23 which results in TIO via uncontrolled renal loss of phosphate (phosphaturia), and consequently diminished bone mineralization. To date, ∼300 cases have been reported. Although there is increasing evidence that PMT can be diagnosed by reproducible histopathologic features, firm diagnosis has been often restricted to cases associated with TIO and, hence, diagnosis of "nonphosphaturic variants" remained challenging...

Vitamin D deficiency is effective in the development of acute rhinosinusitis and prolongation of inflammation by increasing inflammation in the sinonasal epithelium. Vitamin D deficiency is important in the development of bone barriers that prevent the complication of acute rhinosinusitis. Although Vitamin D levels may be a variable risk factor for various respiratory tract disorders, there are limited data on the role in sinonasal infections. Our aim was to investigate the association of 25-hydroxy-vitamin D (25OHD) levels with acute rhinosinusitis (ARS) and preseptal cellulitis complications...

Myeloid sarcoma is a rare malignant extramedullary neoplasm of myeloid precursor cells. The majority of these cases occur in patients with known leukemia or those who eventually develop the disease. It can occur in various sites but sinonasal cavity involvement along with invasive fungal infection is exceedingly rare.

BACKGROUND: Poor prognosis of sinonasal cancers (SNC) is usually due to the non-specific symptoms leading to late diagnosis with locally advanced disease. However, previous prognostic studies were often based on heterogeneous cohorts because of the scarcity of SNC. With squamous cell carcinoma being the main histological subgroup, the study aimed to perform a prognostic analysis on sinonasal squamous cell carcinoma (SNSCC) particularly, and to evaluate the oncological results of a multimodal therapy...

OBJECTIVES/HYPOTHESIS: Previous studies have shown declines in productivity due to chronic rhinosinusitis (CRS) are correlated with disease-specific quality-of-life (QOL) measures. However, it is unclear which symptom domains contribute primarily to productivity loss. This investigation sought to assess the association between CRS-specific QOL subdomain impairment and productivity loss. STUDY DESIGN: Prospective, multi-institutional, observational cohort study. METHODS: There were 198 patients with refractory CRS enrolled between August 2012 and June 2015...
