The pathogenesis of scarring alopecia in African American women remains poorly understood. Furthermore, the overlapping clinical and histological features present diagnostic challenges. The diagnosis of end stage traction alopecia secondary to traumatic hair styling practices can sometimes present particular challenges. We present a young African American woman with a scarring alopecia. As we describe, a scalp biopsy processed by transverse sections enabled rapid diagnosis and presented advantages over a biopsy processed with vertical sections.
非裔美国女性瘢痕性脱发的发病机制仍未得到充分了解。此外,临床和组织学特征的重叠带来了诊断挑战。因创伤性发型导致的终末期牵引性脱发的诊断有时会带来特殊挑战。我们报告了一名患有瘢痕性脱发的年轻非裔美国女性。如我们所描述的,经横切面处理的头皮活检能够实现快速诊断,并且相较于经纵切面处理的活检具有优势。
