Abstract

Melanoacanthoma is a rare lesion. Melanoacanthoma of external ear is still rarer. We present two cases of melanoacanthoma of external ear in adults which presented as pigmented growths and clinically were suspected as malignant lesions. Histopathology was diagnostic as it demonstrated the characteristic elevated lesion with abundant melanin pigment. No recurrence of the lesion was reported after four years of initial diagnosis. These cases have been presented because of their uncommon location, highlighting the differential diagnoses.

摘要

黑素棘皮瘤是一种罕见的病变。外耳道黑素棘皮瘤更为罕见。我们报告两例成人外耳道黑素棘皮瘤病例，表现为色素性肿物，临床上怀疑为恶性病变。组织病理学检查具有诊断意义，因为它显示出具有丰富黑色素的特征性隆起病变。初次诊断四年后未报告病变复发。之所以呈现这些病例，是因其位置不常见，强调了鉴别诊断。
