External auditory canal cholesteatoma (EACC) is a rare occurrence characterized by the keratinized mass of squamous epithelial cells in the external ear canal, leading to bone erosion and potential damage to surrounding structures. It's often misdiagnosed as otitis externa. Both conditions exhibit similar symptoms, which frequently result in misdiagnosis by clinicians. Though it is more common in older adults, EACC can occur in younger patients, as demonstrated in the case of an 18-year-old male. Insufficient diagnosis and delays in the management of this condition can result in significant complications. While the exact cause remains unclear, contributing factors may include canal trauma, chronic inflammation, or stenosis. We aim to share the experience of this pathology in order to highlight it as a differential diagnosis. This is particularly important in patients presenting with unresolved common ear symptoms.
外耳道胆脂瘤（EACC）是一种罕见病症，其特征为外耳道内鳞状上皮细胞的角质化团块，可导致骨质侵蚀并可能损害周围结构。它常被误诊为外耳道炎。这两种病症症状相似，常导致临床医生误诊。虽然EACC在老年人中更为常见，但也可发生于年轻患者，如一名18岁男性的病例所示。对该病症诊断不足和治疗延误可导致严重并发症。虽然确切病因尚不清楚，但促成因素可能包括耳道创伤、慢性炎症或狭窄。我们旨在分享这种病理学的经验，以便将其作为鉴别诊断加以强调。这在出现未缓解的常见耳部症状的患者中尤为重要。
