Metastasis to parotid gland from non Head and Neck tumors

Most primary tumors spreading metastasis to the parotid gland are usually located in the head and neck region, nonetheless, rarely, parotid gland can also be the target of metastatic localization site of distant primary tumors. The purpose of this study was to describe a clinical series of metastasis to the parotid gland from distant primary tumors (non Head & Neck)

Malignant Versus Benign Tumors of the Sinonasal Cavity: A Case-Control Study on Occupational Etiology

Case-control studies on malignant sinonasal tumors and occupational risk factors are generally weakened by non-occupational confounders and the selection of suitable controls. This study aimed to confirm the association between sinonasal malignant tumors and patients' occupations with consideration for sinonasal inverted papillomas (SNIPs) as a control group. Thirty-two patients affected by adenocarcinoma (ADC) and 21 non-adenocarcinoma epithelial tumors (NAETs) were compared to 65 patients diagnosed with SNIPs. All patients were recruited in the same clinical setting between 2004 and 2016. A questionnaire was used to collect information on non-occupational factors (age, sex, smoking, allergies, and chronic sinusitis) and occupations (wood- and leather-related occupations, textile industry, metal working). Odds ratios (OR) with 95% confidence intervals (CI) associated with selected occupations were obtained by a multinomial and exact logistic regression. Between the three groups of patients, SNIP patients were significantly younger than ADC patients (p = 0.026). The risk of NAET increased in woodworkers (OR = 9.42; CI = 1.94\u207b45.6) and metal workers (OR = 5.65; CI = 1.12\u207b28.6). The risk of ADC increased in wood (OR = 86.3; CI = 15.2\u207b488) and leather workers (OR = 119.4; CI = 11.3\u207b1258). On the exact logistic regression, the OR associated to the textile industry was 9.32 (95%CI = 1.10\u207bInf) for ADC, and 7.21 (95%CI = 0.55\u207bInf) for NAET. Comparing sinonasal malignant tumors with controls recruited from the same clinical setting allowed demonstrating an increased risk associated with multiple occupations. Well-matched samples of cases and controls reduced the confounding bias and increased the strength of the association

Update on Vertigo in Autoimmune Disorders, from Diagnosis to Treatment

The prevalence of autoimmune diseases has been increasing over the last 20 years. The clinical presentation of this large and heterogeneous group of disorders depends on whether the involvement is organ-specific or non-organ-specific. Dizziness, vertigo, and disequilibrium are common symptoms reported by patients with vestibulocochlear involvement. The association of vertigo and autoimmune diseases has been largely documented, suggesting that autoimmune disorders could be overrepresented in patients with vertigo in comparison to the general population. The aim of this review is to present the recent literature findings in the field of autoimmune-mediated diseases with cochleovestibular involvement, focusing on the clinical presentation, diagnosis, and treatment of immune-mediated inner ear diseases including autoimmune inner ear disease (AIED), Meniere’s disease, and bilateral vestibulopathy, as well as of systemic autoimmune diseases with audiovestibular disorders, namely, Behçet’s disease, Cogan’s syndrome, sarcoidosis, autoimmune thyroid disease, Vogt-Koyanagi-Harada syndrome, relapsing polychondritis, systemic lupus erythematosus, antiphospholipid syndrome, IgG4-related disease, and ANCA-associated vasculitides

Combined Surgical Approach to Giant Cholesteatoma: A Case Report and Literature Review

OBJECTIVES: Cholesteatomas can grow to a remarkable size before clinically making their presence felt. Managing giant cholesteatomas and their complications can become a challenge for the otological surgeon. METHODS: We describe a case of a giant congenital cholesteatoma of the mastoid in an adult. The lesion extended to the sigmoid sinus, jugular bulb, carotid canal, occipital condyle, and the lateral portion of the first cervical vertebra. Surgical excision was performed using a combined microscopic and endoscopic surgical approach. RESULTS: Our combined surgical technique enabled a more accurate removal of the cholesteatoma than a microscopic approach alone, with no surgical complications or damage to the structures affected by the disease. CONCLUSIONS: Using endoscopic instruments to manage giant cholesteatomas can help to avoid complications and improve surgical radicality

18F-FDG PET/MRI of Rhinosporidiosis of the Upper Airways

A 41-year-old man from South Asia presented with a several months' history of unilateral nasal obstruction and bleeding. At nasal endoscopy, two strawberry-like, friable, polypoid masses in the upper airways were detected. The patient's clinical trait was compatible with an infectious disease. F-FDG PET/MRI was performed to evaluate the disease extension. Two lesions occupying the nasal cavity and the nasopharynx, slightly hyperintense in T2-weighted sequences, with intense radiopharmaceutical uptake were evidenced. Endoscopic resection was performed with histopathologic diagnosis of rhinosporidiosis, a chronic granulomatous disease caused by Rhinosporidium seeberi. Although rare, rhinosporidiosis should be considered in the differential diagnoses of sinonasal hypermetabolic lesions

Ear, nose, and throat in ANCA-associated vasculitis: a comprehensive review

Ear, nose, and throat (ENT) involvement is a common feature in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), particularly in granulomatosis with polyangiitis and eosinophilic granulomatosis with polyangiitis. Over the last decade, substantial advancement has been made in understanding AAV pathogenesis, classification, and treatment. Typical ENT symptoms may include sinonasal, otologic, pharyngeal, and laryngeal manifestations. The otolaryngologic symptoms of AAV sometimes might be misdiagnosed in etiology as infectious or allergic. Thus, rapid recognition and early diagnosis of AAV as the cause of the symptoms prevent the risk of irreversible organ damage. The high impact of ENT symptoms on the quality of life of AAV patients confirms the importance of their early treatment through specific local and systemic approaches. Appropriate interdisciplinary management to early recognition of AAV and initiation of treatment may reduce morbidity in these patients. The purpose of this comprehensive review is to describe the clinical, histological, and radiological findings of ENT involvement in AAV and to update their surgical and therapeutic management, with a focus also on the role of a multidisciplinary team, involving the otorhinolaryngologist
