Abstract:
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.
