A 25-year-old Japanese man developed numerous discrete umbilicated papules on his face, trunk, and both forearms at the onset of IgA nephropathy. The newest lesion was a nonumbilicated skin-colored papule. On histopathologic examination, alteration of capillaries was observed in both newer and umbilicated papules. In our case, a primary cause of the reactive perforating collagenosis could be an alteration of the capillaries.
一名25岁的日本男性在IgA肾病发病时，面部、躯干和双侧前臂出现了许多孤立的脐凹状丘疹。最新出现的损害是一个非脐凹状的肤色丘疹。组织病理学检查发现，较新的丘疹和脐凹状丘疹均有毛细血管改变。在我们的病例中，反应性穿通性胶原病的主要病因可能是毛细血管改变。
