Alopecia of a scalp shows various shapes and extents of hair loss, from a small round patch to polymorphous patches or total global alopecia. But alopecia of a linear shape is very rare. Only a few such cases have currently been reported in the medical literature. We recently had the chance to observe and treat two cases of linear alopecia that developed on the occipital scalp. The lesions themselves were like alopecia areata that shows a smooth bald area without any abnormality except the hair loss, but histopathologically, the lesions were compatible with lupus erythematosus profundus.
头皮脱发表现出各种形状和程度的毛发缺失,从小的圆形斑块到多形性斑块或全秃。但线状脱发非常罕见。目前医学文献中仅报道了少数此类病例。我们最近有机会观察和治疗了两例发生在枕部头皮的线状脱发病例。病变本身类似斑秃,表现为光滑的秃发区,除脱发外无任何异常,但组织病理学上,病变符合深部红斑狼疮。
