The starburst pattern is the dermoscopic hallmark of pigmented Spitz nevus, although it has been rarely observed in melanoma as well.
To describe a case of melanoacanthoma simulating pigmented Spitz nevus.
Clinical, dermoscopic, and histopathologic examinations were performed for the occurrence of a 4-mm pigmented skin lesion on the hip of a 38-year-old Caucasian woman.
Dermoscopy examination of the lesion disclosed a stereotypical starburst pattern characterized by pigmented streaks symmetrically distributed at the periphery. A preoperative diagnosis of pigmented Spitz nevus was made, and the lesion was excised. However, subsequent histopathologic examination revealed a melanoacanthoma.
The starburst pattern, although diagnostic for pigmented Spitz nevus, can be rarely observed in other benign or malignant pigmented skin lesions. Accordingly, all lesions in adults exhibiting a starburst pattern or other spitzoid features should be excised for histopathologic evaluation.
星爆模式是色素性斯皮茨痣的皮肤镜特征，尽管在黑色素瘤中也很少见。
描述一例模拟色素性斯皮茨痣的黑素棘皮瘤病例。
对一名38岁白种女性臀部出现的4毫米色素性皮肤病变进行临床、皮肤镜和组织病理学检查。
对该病变进行皮肤镜检查发现典型的星爆模式，其特征为色素沉着条纹对称分布于周边。术前诊断为色素性斯皮茨痣，病变被切除。然而，随后的组织病理学检查显示为黑素棘皮瘤。
星爆模式虽然是色素性斯皮茨痣的诊断依据，但在其他良性或恶性色素性皮肤病变中很少见。因此，所有表现出星爆模式或其他斯皮茨样特征的成人病变均应切除以进行组织病理学评估。
