Abstract

Nevus is a benign melanocytic neoplasm and the most common type of skin tumor. It may occur anywhere on the skin, but it is rare in the external auditory canal (EAC). We present a case of melanocytic nevus in the EAC with keratin accumulation. In microscopic surgery, the mass was excised completely, and the wax and keratin material medial portion of the EAC behind the mass was removed. In this patient, a melanocytic nevus in the EAC caused symptoms of hearing loss and wax and keratin buildup. For melanocytic nevus in the EAC, excision and pathologic confirmation should be performed if there are symptoms or when malignant transformation is suspected.

外耳道黑色素细胞痣伴角蛋白积累。
痣是一种良性黑色素细胞肿瘤,是最常见的皮肤肿瘤类型。它可能发生在皮肤的任何地方,但在外耳道(EAC)是罕见的。我们报告一例黑色素细胞痣在EAC与角蛋白积累。在显微手术中,肿块被完全切除,肿块后面EAC内侧部分的蜡和角蛋白物质被去除。在这个病人,黑素细胞痣在EAC引起听力丧失和蜡和角蛋白堆积的症状。对于EAC的黑素细胞痣,如有症状或怀疑恶性转化时,应行手术切除和病理证实。
