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: Laryngeal cysts are heterogeneous in their clinical presentation and several classifications have been proposed. Here, we report the case of a foraminal laryngeal cyst in a 6 year-old child who also has hemi facial microsomia (HFM). The cyst was treated surgically with laryngotracheal endoscopy followed by cervicotomy. Histological analysis revealed different types of cystic wall epithelium. This case is the first report of a laryngeal cyst associated with HFM in the literature. We discuss the diagnostic challenges of these specific cystic pathologies, and their pathogenesis as part of an oculo-auriculo-vertebral spectrum. Several hypotheses are proposed, based mainly on characterization of their embryological origin. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    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.
