Amyloidosis comprises a heterogeneous group of disorders characterized by the deposition of amyloid protein in various organs of the body. The larynx is one of the rarer sites where amyloidosis occurs.
A 36-year-old man presented with a two-year history of hoarseness of voice. He had a positive history of smoking, but no history of long-term consumption of alcohol. Physical examination revealed a pinkish mass about 1.5× 1.5 cm in size on his left False Vocal Cord (FVC) extending to the left arytenoid, which resulted in asymmetry of the posterior larynx. He also had a chronic perforation of the right tympanic membrane with a conductive hearing loss consisting of a 50 dB gap in pure tune audiometry. The FVC mass was excised with a CO2 laser and on follow-up his voice got much better, but the hoarseness was not fully resolved.
Amyloidosis of the larynx is a rare, usually benign process but the area is the most common site for isolated amyloid deposits to occur in the head and neck.
淀粉样变性是一组异质性疾病,其特征是淀粉样蛋白在身体各器官中沉积。喉部是淀粉样变性较少见的发病部位之一。
一名36岁男性,有两年声音嘶哑病史。他有吸烟史,但无长期饮酒史。体格检查发现其左侧假声带(FVC)有一粉红色肿物,大小约1.5×1.5厘米,延伸至左侧杓状软骨,导致喉后部不对称。他还患有右鼓膜慢性穿孔,伴有传导性听力损失,纯音听力测定有50分贝的差距。用二氧化碳激光切除了FVC肿物,随访时他的声音有了很大改善,但嘶哑并未完全消除。
喉部淀粉样变性是一种罕见的、通常为良性的病变,但该部位是头颈部孤立性淀粉样沉积物最常见的发生部位。
