Androgenetic alopecia is often treated by follicular unit transplantation, a technique that involves minimal risk of hair loss because of the more resistant nature of the donor area. Lichen planopilaris is a cicatricial alopecia that causes permanent destruction of hair follicles. We report two cases of post-transplantation lesions compatible with lichen planopilaris in both recipient and donor areas. The quality of the hair follicles in the donor area was apparently compromised by lichen planopilaris, the probable cause of hair loss. Similar reports are rare. When lichen planopilaris is suspected, a biopsy of the scalp must be performed to avoid transplantation during disease activity.
雄激素性脱发通常采用毛囊单位移植治疗，该技术因供体区域毛发更具抗性，故脱发风险极小。扁平苔藓性毛囊病是一种瘢痕性脱发，可导致毛囊永久性破坏。我们报告了两例在受区和供区均出现与扁平苔藓性毛囊病相符的移植后病变的病例。供体区域的毛囊质量显然受到扁平苔藓性毛囊病的影响，这可能是脱发的原因。类似的报告很少见。当怀疑患有扁平苔藓性毛囊病时，必须对头皮进行活检，以避免在疾病活动期进行移植。
