The incidence of intradermal nevus in the external auditory canal is uncommon. We herein are describing a case of 60-year-old lady who presented with foreign body sensation in the right external ear canal (EAC) with mild discomfort and ear bleed during ear picking. Otoscopic examination revealed hyperpigmented mass on the floor of the outer two third of EAC. Complete excisional biopsy of the mass resulted in histopathology findings of intradermal nevus. Despite the fact that the disease is not alarming, the possibilities of benign melanocytic nevi transformation into malignant lesions such as melanoma need to be ruled out.
外耳道皮内痣的发病率并不常见。我们在此描述一例60岁女性病例,该患者右外耳道有异物感,伴有轻度不适,掏耳时出现耳部出血。耳镜检查发现外耳道外三分之二底部有色素沉着肿物。对该肿物进行完整切除活检,组织病理学结果为皮内痣。尽管该病并不令人担忧,但仍需排除良性黑素细胞痣转变为恶性病变(如黑色素瘤)的可能性。
