BACKGROUND: Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade tumour of salivary glands that was first described as a distinct entity in 1994 by Milchgrub et al. EWSR1-ATF1 fusion was found to be specific for this tumour. The majority of the reported cases of HCCC arise from minor salivary glands within the oral cavity. Primary HCCC of the paranasal sinus is extremely uncommon. To our knowledge, only three cases have been reported in the English literature. Herein, we present a case of HCCC of the posterior ethmoid/maxillary sinus...

BACKGROUND: Tumors invading both the anterior skull base and the sinonasal area have been traditionally accessed via largely invasive open craniofacial approaches. Minimally invasive extended endoscopic endonasal approaches have recently become increasingly available, but have anatomical limitations and require incremental experience and thus high patient volume. Our objective was to assess the applicability of a novel combination of the minimally invasive supraciliary incision and the limited maxillofacial osteotomy as a combined surgical approach for large tumors invading both the anterior skull base and the sinonasal area...

BACKGROUND: Enzootic nasal tumor virus (ENTV) is a betaretrovirus of sheep (ENTV-1) and goats (ENTV-2) associated with neoplastic transformation of epithelial cells of the ethmoid turbinate. Confirmation of the role of ENTV in the pathogenesis of enzootic nasal adenocarcinoma (ENA) has yet to be resolved due to the inability to culture the virus. Very little is known about the prevalence of this disease, particularly in China. METHODS: To evaluate the genetic diversity of ENTV-2 from Shaanxi province of China, the complete genome sequence of four isolates from Shaanxi province was determined by RT-PCR...

BACKGROUND: The purpose of this study was to propose a prognostic classification of intestinal-type adenocarcinoma (ITAC) based on literature search and prognostic modeling of cohort data. METHODS: We first conducted a literature search to assess the homogeneity of the reported estimates of 5-year survival and to identify the influence of T classification. We then pooled prospective data from 3 large French and Italian series to predict time to all-cause mortality...

BACKGROUND: Enzootic nasal tumor virus (ENTV-1) is an ovine betaretrovirus that has been linked to enzootic nasal adenocarcinoma (ENA), a contagious tumor of the ethmoid turbinates of sheep. Transmission experiments performed using virus isolated from cell free nasal tumor homogenates suggest that ENTV-1 is the causative agent of ENA; however, this etiological relationship has not been conclusively proven due to the fact that the virus cannot be propagated in vitro nor is there an infectious molecular clone of the virus...

Intracranial metastasis of prostate cancer is rarely seen, and there are few studies in this regard in the literature. Most of these studies in the literature comprise the metastasis of prostate cancer to the sphenoid sinus, and metastasis to the frontal and ethmoid sinus is a much rare entity. Association of visual symptoms, epistaxis, headache, and hematuria may indicate a urologic malignancy in terms of the origin of the primary tumor. This study was aimed to present the prostate cancer case of a 73-year-old patient whose paranasal sinus tomograms revealed the presence of frontal and ethmoid sinus metastasis...

The nasal cavity and parasinusal cancer are rare (10% of tumors of the head and neck) and are mainly represented by squamous cell carcinoma of the nasal cavity or the maxillary sinus and adenocarcinoma of the ethmoid sinus (occupational disease, wood dust). The most common clinical sign is nasal obstruction, but tumors can also manifest as rhinorrhea and/or epistaxis (usually unilateral signs). A magnetic resonance imaging of the facial structure is systematic for staging before treatment. The treatment consists of a first surgery if the patient is operable with a resectable tumor...

COMPARATIVE STUDY
Geoffrey Mortuaire, Xavier Leroy, Claire Vandenhende-Szymanski, Dominique Chevalier, Anne-Sophie Thisse
Endoscopic sinus surgery (ESS) is considered as a valid option in the management of nasal adenocarcinoma (ADC). Comparative studies with open approaches are still required. A monocentric retrospective study was carried out from May 2002 to December 2013, including 43 patients with intestinal-type adenocarcinoma of the ethmoid sinus. Non-resectable tumours or recurrences were excluded. Before 2008, open approach with lateral rhinotomy (LR) was performed as the gold standard of treatment. From 2008, ESS was systematically used as a first-line option as long as a complete resection was achievable...

Metastatic lesions to the orbit are most commonly seen with breast, lung, and prostate cancer, but are less commonly seen with colon cancer. Furthermore, the presence of metastatic colon cancer involving the sphenoid wing has only been reported once previously. The authors present a case of a 68-year-old woman with right upper and lower eyelid edema and erythema along with decreased vision, relative afferent pupillary defect, limitation of extraocular movements, and chemosis suggestive of orbital cellulitis...

BACKGROUND: Enzootic nasal tumor virus (ENTV-1) is an exogenous betaretrovirus of sheep that transforms epithelial cells lining the ethmoid turbinates leading to a disease called enzootic nasal adenocarcinoma (ENA). A unique feature of ENA is the apparent absence of a specific humoral immune response to the virus, despite the highly productive infection in nasal tumors. The sheep genome contains approximately 27 copies of endogenous ovine betaretroviral sequences (enJSRVs) and expression of enJSRVs in the ovine placenta and uterine endometrium throughout gestation is thought to induce immunological tolerance to exogenous ovine betaretroviruses, a factor that may influence the likelihood of exogenous ENTV infection and disease outcome...

IMPORTANCE: Basal cell adenocarcinoma (BCAC) of the minor salivary gland is an extremely rare disease: the most recent substantive literature review reports only 25 cases. Owing to the rarity of this disease, it has not yet been well characterized in the literature. OBJECTIVE: We sought to expand the knowledge of minor salivary gland BCAC by performing an exhaustive literature review and adding to it a new case that is rare owing to the tumor's size, aggressive nature, and mixed histologic pattern...

OBJECTIVE: Data from several centers worldwide have demonstrated that transnasal endoscopic surgery performed with or without a transcranial approach is capable of achieving radical resection of selected sinonasal malignancies. We report our experience with endoscopic management of sinonasal cancers, with emphasis on naso-ethmoidal malignancies encroaching on the anterior skull base. METHODS: Major series reporting results concerning the endoscopic endonasal approach with or without craniectomy for treatment of sinonasal and anterior skull base cancers were reviewed...
