Abstract：
OBJECTIVE: Though hemorrhagic vocal fold polyps are a common entity, hemorrhagic vocal fold cysts have not been previously described. In our study, we have evaluated patients who were diagnosed on stroboscopy with \"hemorrhagic\" cysts.
METHODS: This 18-month retrospective study has received institutional ethics clearance. Using the database of our voice clinic, 14 patients diagnosed with hemorrhagic cysts by stroboscopy were reviewed. Age, sex, chief complaints, symptom duration, videostroboscopy findings, surgical details, and histopathology were noted.
RESULTS: Out of a total 14 patients, 12 were males with a mean age of presentation of 41 years. The duration of hoarseness ranged from 2-24 months. Videostroboscopy revealed a markedly decreased amplitude of the mucosal waves over a well-delineated ovoid or spheroid hemorrhagic lesion, which seemed tethered down by overlying vocal fold epithelium. All patients had operative findings of a well-encapsulated hemorrhagic lesion in the superficial lamina propria with anterior and posterior fibrotic bands. Histopathology of 13 patients was similar and revealed a hemorrhagic polypoidal lesion. A pseudo-capsule could be identified occasionally. These lesions seemed to be hemorrhagic pseudocysts, named \"polyst\" by us. In one male patient, the histopathology revealed a true vocal fold cyst (type C Koren) with hemorrhage.
CONCLUSIONS: A hemorrhagic pseudocyst (polyst) of the vocal fold has stroboscopic and surgical findings resembling a true vocal fold cyst with hemorrhage; however, histologically it resembles a hemorrhagic polyp. A true hemorrhagic cyst however is typically a type C Koren cyst with hemorrhage. Both these entities have not been previously described.

摘要：
目的：虽然出血性声带息肉是一个常见的实体，出血性声带囊肿以前没有描述。在我们的研究中,我们评估了在频闪镜检查中诊断为“出血性囊肿”的患者。
方法：这项为期18个月的回顾性研究已经获得了机构伦理审查。利用我们语音诊所的数据库，回顾性分析14例经频闪镜检查诊断为出血性囊肿的患者。年龄,性别,首席投诉，症状持续时间,视光镜检查结果,手术细节,并注意到组织病理学。
结果：在总共14名患者中，12为男性，平均年龄为41岁。声音嘶哑的持续时间为2-24个月。视频频闪镜检查显示，在轮廓良好的卵形或球形出血性病变上，粘膜波的振幅显着降低。似乎被上覆的声带上皮束缚住了。所有患者的手术发现均在固有浅层中出现了包裹良好的出血性病变，并带有前后纤维化带。13例患者的组织病理学相似，并显示出血性息肉样病变。偶尔会发现假胶囊。这些病变似乎是出血性假性囊肿，被我们命名为“polyst”。在一名男性患者中，组织病理学显示真性声带囊肿(C型Koren)伴出血.
结论：声带出血性假性囊肿（息肉）具有频闪和手术发现，类似于真正的声带囊肿并出血；然而，组织学上类似于出血性息肉。然而，真正的出血性囊肿通常是伴有出血的C型Koren囊肿。这两个实体以前都没有描述过。
