Solitary Fibrous Tumour: A Rare Differential Diagnosis of Unilateral Nasal Mass.

Solitary fibrous tumors of the nasal cavity and paranasal sinuses are rarely encountered in clinical practice. These are unusual mesenchymal tumours initially described as primary spindle-cell neoplasms. Such tumours may manifest in pleural and extrapleural sites such as the liver, parapharyngeal space, sublingual and parotid glands, and thyroid but are seldom described in the nose and paranasal sinus region. Erosion of adjacent structures may occur, but the tumour itself does not metastasise. A young patient presented with a progressive unilateral nasal mass. The initial nasal biopsy reported it as a benign inflammatory nasal polyp. Imaging revealed a large, locally expansile mass within the right nasal cavity displacing the nasal septum. The patient underwent excision of the tumour and the diagnosis of solitary fibrous tumour was confirmed by immunohistochemistry staining. This case is intended to highlight the diagnosis and management of this rare tumour.

Pleomorphic Adenoma of the Nasal Septum: A Case Report.

Pleomorphic adenoma is the most common benign tumor of major and minor salivary glands. It rarely originates from the nasal cavity. It is important to identify the symptoms and characteristics of the disease so that early diagnosis can be made and appropriate treatment can be offered as it has a risk of malignant transformation. We are reporting a case of a 22-year-old female with a long duration of unilateral nasal obstruction. Rigid nasoendoscopy showed a mass at the left nasal septum. Preoperative imaging was performed followed by endoscopic resection of the mass. The pathological diagnosis was pleomorphic adenoma. Post-operatively, appropriate examination with nasoendoscopy and long-term follow-up is essential to avoid local recurrence.

Challenges in Diagnosing Foreign Body Aspiration in Children.

Foreign body aspiration in children is a medical emergency that is associated with significant morbidity and requires medical intervention. The variability of clinical presentations results in delayed diagnosis and treatment. Hence, a high index of clinical suspicion and a thorough examination is needed to expedite the management. We report the case of a toddler girl who aspirated a piece of peanut and was diagnosed as having bronchopneumonia upon presentation with respiratory symptoms for six days. Rigid bronchoscopy was performed and the foreign body was removed successfully without any complications. We aim to highlight the importance of considering the diagnosis of airway foreign body in children with unexplained respiratory distress in our case study.

Body plethysmography for measuring airway resistance in patients with bilateral vocal fold immobility.

OBJECTIVE: This study investigated the reliability of body plethysmography in comparison to spirometry in objectively measuring upper airway functions. METHODS: The study population consisted of 53 participants, 23 patients with BVFI after endolaryngeal laser posterior cordectomy and 30 healthy volunteers. All of them had body plethysmography (airway resistance, Raw), spirometry (ratio of forced expiratory flow at 50% to forced inspiratory flow at 50%, FEF50/FIF50 and peak inspiratory flow, PIF), 6 min-walking-test (6MWT) and Medical Research Council (MRC) dyspnea scale measurements. The tests were repeated and reliability was evaluated using intraclass correlation (ICC) and Spearman correlation. RESULTS: The reliability of Raw was high with ICC of 0.92, comparable to the spirometry measurements: FEF50/FIF50(ICC = 0.72) and PIF (ICC = 0.97). The mean of Raw was significantly higher in patient group. A strong significant correlation between Raw and MRC dyspnea scale (r = 0.79; p<0.05) and a moderate negative correlation between Raw and 6MWT (r = 0.4; p<0.05) was demonstrated. CONCLUSION: Body plethysmography (Raw) is a reliable tool in objective measurement of upper airway resistance that reflects the patient's perception of breathlessness. A larger number of participants are necessary to confirm this finding.

Management of a Rare Lymphoepithelial Carcinoma of the Submandibular Gland in Elderly.

Lymphoepithelial carcinoma (LEC) of salivary glands is a rare malignant salivary gland tumour and demonstrates genetic and regional distribution. It commonly occurs in major salivary gland especially parotid gland. We report a case of LEC of submandibular gland occurring in a 70 year-old lady.
