Laryngeal oncocytic cystadenomas are rare benign tumours lined by oncocytic epithelium and arising from the salivary glands; they usually present as a supraglottic mass. Oncocytic changes are very uncommon in the larynx and occur mainly in ventricles and false vocal cords, where seromucinous glands predominate. The authors present the case of a 62-year-old woman who reported a 6-month history of hoarseness associated with a soft and non-compressible upper left side neck swelling. Transnasal fiberoptic laryngoscopy revealed a left submucosal supraglottic mass involving the false vocal fold and the vallecula, partially obstructing the airway. CT scan showed a homogeneous isodense cystic lesion centred at the left laryngeal ventricle, with extension through the thyrohyoid membrane. The patient was successfully managed by a lateral thyrotomy approach. Histopathological examination of the specimen revealed a papillary oncocytic cystadenoma and excluded malignancy. There was no evidence of recurrence after 9 months of follow-up.
喉涎腺型嗜酸细胞瘤是一种罕见的良性肿瘤，由嗜酸细胞上皮构成，来源于涎腺；它们通常表现为会厌前间隙肿块。嗜酸细胞改变在喉部非常罕见，主要发生在室带和假声带，那里以浆液黏液腺为主。作者报告了一例 62 岁女性病例，该患者因声音嘶哑就诊，伴有 6 个月的左侧上颈部柔软且不可压缩性肿胀史。经鼻纤维喉镜检查显示左侧会厌前间隙黏膜下肿块累及假声带和杓会厌皱襞，部分阻塞气道。CT 扫描显示左喉室中心位置存在均匀等密度囊性病变，通过甲状舌骨膜延伸。患者通过外侧甲状腺切开术成功治疗。标本的组织病理学检查显示为乳头状嗜酸细胞瘤囊腺瘤，排除了恶性肿瘤。随访 9 个月后无复发证据。
