Laryngeal hemangioma is a rare benign tumor of the larynx with predilection for a supraglottal subsite. Common presentations include hoarseness, dyspnea, and dysphagia, with a typical appearance of a reddish-purplish mass. A capillary form of the tumor, lobular capillary hemangioma (LCH) is extremely rare in adults and is predominantly unilateral. Diagnosis is made histologically by the distinct lobular growth pattern of capillary proliferation. Here, we report a 50-year-old male chronic smoker who presented with 3-month history of progressive hoarseness, dry cough, and intermittent dyspnea. Flexible endoscopy of the larynx showed irregular pinkish-white masses on the middle third of the bilateral vocal folds. The provisional diagnosis of glottic carcinoma was ruled out by histopathology, and the final diagnosis was bilateral glottic LCH, making it the first recorded case of this condition in literature. The patient underwent endolaryngeal microsurgery with subepithelial excision, a procedure that can be both diagnostic and therapeutic for this rare tumor.
喉血管瘤是一种罕见的喉部良性肿瘤，好发于声门上亚部位。常见表现包括声音嘶哑、呼吸困难和吞咽困难，典型表现为红紫色肿块。肿瘤的一种毛细血管形式，即小叶状毛细血管血管瘤（LCH）在成人中极为罕见，且主要为单侧性。通过毛细血管增生独特的小叶状生长模式进行组织学诊断。在此，我们报告一名50岁男性慢性吸烟者，有3个月进行性声音嘶哑、干咳和间歇性呼吸困难病史。喉镜检查显示双侧声带中三分之一处有不规则粉白色肿块。组织病理学排除了声门癌的初步诊断，最终诊断为双侧声门LCH，这使其成为文献中该病症的首例记录病例。患者接受了喉内显微手术及上皮下切除术，该手术对这种罕见肿瘤兼具诊断和治疗作用。
