Laryngeal cysts: clinical relevance of a modified working classification.
ABSTRACT Laryngeal cysts from 72 patients were examined and reclassified according to a modified working classification. In this series, 47 patients (66 per cent) had epithelial cysts, 11 patients (15 per cent) oncocytic cysts and 14 patients (19 per cent) tonsillar cysts. Epithelial cysts were commonest in the region of the epiglottis (20/47) and laryngeal ventricle (24/47). Oncocytic cysts tended to lie in the region of the ventricle whereas tonsillar cysts occurred almost exclusively in the valleculae, epiglottis and pyriform region (13/14). The authors conclude that the modified working classification of laryngeal cysts is easy to apply, of clinical relevance, and allows classification of cysts where operative trauma to the specimen obscures the relationship of the cyst to the surface epithelium. The origin and significance of tonsillar cysts are discussed and a relationship to the lympho-epithelial cyst of the oral cavity is suggested.

ABSTRACT: Ectopic tonsillar tissue simulating a benign tumor of the hypopharynx is described in this report. We report the case of a 79-year-old Japanese woman with globus sensation. Because clinical observation revealed benign features, tumor tissue was laryngoscopically resected. From the pathological features, for example, existence of germinal center, lymphoid tissue, and crypt involving lymphoepithelial symbiosis, we diagnosed that the lesion was a hyperplasia of ectopic tonsillar tissue. Although ectopic tonsillar tissue of the hypopharynx is relatively rare, it should be kept in mind during differential diagnosis.Journal of Medical Case Reports 01/2010; 4:388.

ABSTRACT: OBJECTIVES: To expose the rarity of the phenomena of congenital laryngeal cysts. Additionally, a discussion is presented in support of the basic similarities between laryngeal duplication cyst and bronchogenic cyst and a proposal to use the term 'bronchogenic cyst' (appended by the location) is put forth. MATERIALS AND METHODS: Three cases of cysts of the larynx, two in the neonate and one, in a child were discovered in the pediatric age group from the archives of the Department of Pathology, Kasturba Medical College, Mangalore. OBSERVATIONS: Laryngeal duplication cyst/bronchogenic cyst in a 6-day-old male infant was lined by predominantly respiratory with focal squamous epithelium. The wall contained fibromuscular bundles within a myxoid stroma studded with seromucinous glands. The fibromuscular bundles were positive for smooth muscle actin (SMA) and negative with desmin. A 3-year-old male child diagnosed of laryngocele had the cyst lined by respiratory epithelium and the wall densely infiltrated with lymphoid cells. A 20-day-old male neonate with laryngomalacia had a small arytenoid cyst lined by squamous epithelium. CONCLUSION: On morphological grounds, a laryngeal duplication cyst may be called a bronchogenic cyst and published reports do not deny that both these entities are cognate. Hence, pathologists should enjoy the freedom to write 'bronchogenic cyst' as the final impression if the histological features should so indicate. Otolaryngologtists however might term the congenital cyst as Type 1, 2a or 2b (according to Forte's classification) taking into account the laryngoscopic, radiologic, intraoperative and pathological findings.International journal of pediatric otorhinolaryngology 05/2013; · 0.85 Impact Factor

ABSTRACT: In larynx cysts may be localized in different regions: glottis, laryngeal pouch, epiglottis, aryepiglottic folds and subglottic area. It is difficult to estimate if the cyst is acquired or congenital. Symptoms of laryngeal cyst depend on the size and localization of the cyst and include: change in the tone of voice, dysphonia, hoarseness, dysphagia, laryngeal stridor and dyspnoea. Cysts of the larynx in infants are rare but the treatment is easy once the diagnosis is made. If mismanaged, the resulting respiratory obstruction can lead to serious complications. Analysis of cases of laryngeal cyst in children treated in the Department of Paediatric ENT Medical University of Warsaw. A retrospective analysis of 10 cases of laryngeal cyst in children treated in the Department of Paediatric ENT in Warsaw between 2000 and 2008 was made. The authors analyzed indications to directoscopy, endoscopic presentation, problems with establishing the right diagnosis and management. Using a direct laryngoscopy as a golden standard in children with stridor will reduce a number of false diagnosis.International journal of pediatric otorhinolaryngology 10/2009; 73(12):1729-31. · 0.85 Impact Factor
