We report an unusual case of ectopic cervical thymoma. A 35-year-old female patient presented with an anterior neck mass that developed over a five-month duration. The patient underwent fine-needle aspiration cytology (FNAC) twice, but the tumor type could not be diagnosed. The surgically removed tumor was white in color and had a smooth surface. According to the postoperative pathological examination, the tumor was diagnosed as a Stage I ectopic cervical thymoma and Type B1 according to the Masaoka staging system and the World Health Organization (WHO) histological staging system, respectively. The patient was in good overall health and remained without tumor recurrence at the time of the 10-month follow-up. Because it was difficult to make a preoperative definite diagnosis by FNAC for the thymoma, we constructed a cell block from the existing cytological specimen. Immunohistological staining using the cell-block method clearly demonstrated the biphasic cellular population pattern that is a characteristic of thymoma. Therefore, this method may be useful as a preoperative differential diagnostic modality for cervical thymomas.

There are many methods and types of equipment for measuring the nasal airway, but there is no consensus regarding the results of various clinical studies on nasal obstruction. In this review, we discuss the two major methods of objectively assessing the nasal airway: rhinomanometry and acoustic rhinometry. The Japanese standard of rhinomanometry in Japanese adults and children was established by the Japanese Standardization Committee on Rhinomanometry in 2001 and 2018, respectively. However, the International Standardization Committee has proposed different standards because of differences in race, equipment, and social health insurance systems. The standardization of acoustic rhinometry in Japanese adults is making progress in several Japanese institutes, but the international standardization of acoustic rhinometry has not yet begun. Rhinomanometry is the physiological expression of nasal airway breathing, whereas acoustic rhinometry is the anatomic expression. In this review, we introduce the history and methods of the objective assessment of nasal patency and the physiological and pathological issues regarding nasal obstruction.

Many patients with allergic rhinitis have accompanying laryngeal symptoms such as persistent cough and/or globus. Chronic laryngeal allergy is suspected to be an important cause of these laryngeal symptoms. We have been working toward establishing the concept of a new pathological condition termed “laryngeal allergy” since 1988. In Japan, the first diagnostic criteria for laryngeal allergy were established in 1995. However, these early criteria were inadequate because there was inadequate distinction between laryngeal allergy and other causes of persistent cough and globus. Therefore, more advanced criteria were reconstructed from a completely different viewpoint in 2005 to correctly distinguish laryngeal allergy from other similar diseases. The criteria established in 2005 were modified slightly in 2011 to improve the diagnostic accuracy based on the results of fundamental and clinical investigations. The Japanese Respiratory Society (JRS) included chronic laryngeal allergy in the diagnostic flowchart of the JRS guidelines for the management of cough and sputum in 2019, and chronic laryngeal allergy has recently gained wider recognition in Japan. The accurate diagnosis of conditions resembling laryngeal allergy is important in controlling cough and/or globus and preventing the unnecessary use of medical resources. Therefore, further investigations are warranted to better understand laryngeal allergy and similar diseases.
