Follicular unit extraction (FUE) is a popular hair transplant technique, which involves extraction of follicular grafts from the donor area, usually occipital area of scalp. We have described few cases where non-scarring alopecia patches appeared at donor area similar to that of alopecia areata clinically, after 2-3 weeks of surgery. Even trichoscopically, findings were similar to alopecia areata showing exclamation marks, black dots. However, on histopathology, there were dilated blood vessels, mucin deposition, and only few lymphocytes, which mimic histopathology of healing wound. We hypothesize that compromised blood supply and trauma to the existing hairs after harvesting can lead to post-hair transplant effluvium, which is probably due to anagen effluvium.
毛囊单位提取（FUE）是一种流行的毛发移植技术，该技术涉及从供体区域，通常是头皮的枕部区域提取毛囊移植物。我们描述了几例在手术后2 - 3周，供体区域出现类似于斑秃的非瘢痕性脱发斑的病例。即使在毛发镜检查中，表现也与斑秃相似，显示有感叹号、黑点。然而，在组织病理学上，有扩张的血管、粘蛋白沉积，仅有少量淋巴细胞，这类似于愈合伤口的组织病理学表现。我们推测，采集后现有毛发的血液供应受损和创伤可导致毛发移植后脱发，这可能是由于生长期脱发所致。
