Most nodal nevi are intracapsular and present the morphology of conventional nevi; less frequently, they show the appearance of common and cellular blue nevi. We report a case of an nodal capsular, trabecular and intraparenchymal melanocytic nevus with balloon-cell change in a patient with a malignant melanoma which arose in a pre-existing cutaneous giant congenital nevus, showing balloon-cell degeneration.
大多数结节性痣位于包膜内，呈现传统痣的形态；较少见的情况下，它们表现出普通蓝痣和细胞蓝痣的外观。我们报告一例患有恶性黑色素瘤的患者，其结节性包膜、小梁状和实质内黑素细胞痣伴气球样细胞改变，该恶性黑色素瘤发生于先前存在的皮肤巨大先天性痣，表现为气球样细胞变性。
