Pleomorphic adenomas of the external auditory canal (EAC) are benign tumors of the ceruminal glands; they are a rare entity. Arising from the lateral cartilaginous portion of the EAC, these lesions can be challenging to diagnose in view of their rare clinical presentation, indolent symptoms, and a lack of familiarity on the part of histopathologists. We report the case of a pleomorphic adenoma in a 32-year-old woman, and we review the literature on glandular neoplasms of the EAC, with particular emphasis on terminology and factors that can hinder the diagnosis.
外耳道多形性腺瘤是耵聍腺的良性肿瘤，是一种罕见的病变。这些病变起源于外耳道的外侧软骨部分，鉴于其罕见的临床表现、隐匿的症状以及组织病理学家对此缺乏了解，其诊断具有挑战性。我们报告了一例32岁女性的多形性腺瘤病例，并回顾了有关外耳道腺性肿瘤的文献，特别强调了可能妨碍诊断的术语和因素。
