Hemangiomas account for only 0.4% to 0.6% of all parotid tumors, making them extremely rare in adults. Unlike pediatric parotid hemangiomas, those in adults typically present as asymptomatic swellings of the parotid, have no skin discoloration, and usually do not regress spontaneously. Therefore, an accurate diagnosis of parotid hemangiomas in adults before surgical excision is generally challenging. Herein, we present 3 cases of adult parotid hemangiomas. The patients all received parotidectomies with tumor resection. Histopathological analysis of the resected specimens revealed numerous dilated, thin- or thick-walled (small, large, or variably sized) vessels lined with flattened endothelial cells. A diagnosis of cavernous hemangioma of the parotid gland was established only after the histopathological analysis. Parotid cavernous hemangiomas in adults are rare and often misdiagnosed before surgical resection. Clinical presentation and imaging features on ultrasonography, computed tomography, magnetic resonance imaging, and angiography may support an accurate preoperative diagnosis. Surgical resection proved a suitable treatment approach for our 3 cases.
血管瘤仅占所有腮腺肿瘤的 0.4%至 0.6%，在成人中极为罕见。与小儿腮腺血管瘤不同，成人腮腺血管瘤通常表现为无症状的腮腺肿胀，无皮肤变色，通常不会自发消退。因此，在手术切除前准确诊断成人腮腺血管瘤通常具有挑战性。本文介绍了 3 例成人腮腺血管瘤患者。所有患者均接受了腮腺切除术和肿瘤切除术。切除标本的组织病理学分析显示，有许多扩张的、薄壁或厚壁（小、大或不同大小）血管，内衬扁平内皮细胞。只有在组织病理学分析后才能诊断为腮腺海绵状血管瘤。成人腮腺海绵状血管瘤罕见，常在手术切除前误诊。超声、计算机断层扫描、磁共振成像和血管造影的临床表现和影像学特征可能有助于术前准确诊断。手术切除对我们的 3 例患者均是一种合适的治疗方法。
