A 63-year-old male presented with a prolonged history of bilateral ear discharge, otalgia, and hearing loss. The patient required a significant number of investigations prior to obtaining a diagnosis. Subsequent investigations identified keratoacanthoma affecting the external ear canal (EAC). There has been no case report of keratoacanthoma within the EAC till now. The only risk factor identified for the development of keratoacanthoma, in this case, was the frequent use of earbuds and subsequent long-term trauma associated with a retained bud. The histology of keratoacanthoma is difficult to differentiate from that of squamous cell carcinoma but this is essential for the ear, nose, throat (ENT) multi-disciplinary team.
一名63岁男性，有双侧耳溢液、耳痛和听力损失的长期病史。在获得诊断之前，该患者需要进行大量检查。随后的检查发现外耳道（EAC）患有角化棘皮瘤。迄今为止，尚无外耳道角化棘皮瘤的病例报告。在该病例中，确定的角化棘皮瘤发生的唯一风险因素是频繁使用耳塞以及随后因耳塞残留而导致的长期创伤。角化棘皮瘤的组织学很难与鳞状细胞癌相区分，但这对耳鼻喉科（ENT）多学科团队来说至关重要。
