. Hidrocystomas are benign cystic growths of the apocrine and eccrine sweat glands. These cystic lesions have been well documented on the face, head, and neck, but rarely in the external auditory canal. . A 67-year-old woman presented with a bluish cystic mass partially occluding the external auditory canal and interfering with hearing aid use. Lesion was excised completely via a transcanal endoscopic approach with excellent cosmetic results, no canal stenosis, and no recurrence at 1-year follow-up. . We present a rare eccrine hidrocystoma of the external auditory canal and successful excision of this benign lesion. We describe the surgical management using a transcanal endoscopic approach and follow-up results. An eccrine gland cyst that presents as a mass occluding the external auditory canal is quite rare. There are only a few such cases reported in the literature. These masses can be mistaken for basal cell carcinomas or cholesterol granulomas but can be easily differentiated using histopathology. . Eccrine hidrocystoma is a cystic lesion of sweat glands, rarely found in the external auditory canal. A characteristic bluish hue aids in diagnosis and surgical excision using ear endoscopy provides excellent control.
汗腺囊瘤是顶泌汗腺和小汗腺的良性囊性肿物。这些囊性病变在面部、头部和颈部已有充分记载，但在外耳道却很少见。一名67岁女性患者，其外耳道有一蓝色囊性肿物，部分阻塞外耳道并影响助听器使用。通过经耳道内镜手术完全切除病变，术后美容效果极佳，无耳道狭窄，随访1年无复发。我们报道了1例罕见的外耳道小汗腺囊瘤，并成功切除了这一良性病变。我们描述了经耳道内镜手术的治疗方法及随访结果。表现为阻塞外耳道肿物的小汗腺囊肿非常罕见。文献中仅有少数此类病例报道。这些肿物可能被误诊为基底细胞癌或胆固醇肉芽肿，但通过组织病理学检查很容易鉴别。小汗腺囊瘤是一种汗腺囊性病变，很少见于外耳道。其特征性的蓝色有助于诊断，使用耳内镜进行手术切除可实现良好的控制。
