Since then, balloon-cell changes of melanocytes have been noted in numerous tumors, including melanoma, blue nevus, and Spitz nevus. Whether these changes reflect cellular deterioration or proliferative changes is a matter of debate. We report a case in which balloon-cell changes were found within proliferative nodules occurring in a large congenital melanocytic nevus.展开更多
