A case of scarring alopecia presenting as two circumscribed, tender and inflamed areas in the occiput with residual tufted follicles is reported. Each tuft comprised 10 to 15 normal-appearing hairs arising from individual hair follicles in the reticular dermis or subcutaneous fat, converging toward a single orifice in the epidermis. The initial pathologic finding was inflammation and scarring of the papillary and mid dermis with almost total sparing of the hair follicles in the subcutaneous fat. Successful treatment was achieved by surgical excision of the two areas. It is suggested that the areas of tufting represented nevoid lesions that underwent inflammation and scarring.
报告了一例瘢痕性脱发病例，表现为枕部两个边界清楚、压痛且发炎的区域，伴有残留的簇状毛囊。每个毛囊簇由10至15根外观正常的毛发组成，这些毛发从网状真皮或皮下脂肪中的单个毛囊长出，向表皮中的单个孔口汇聚。最初的病理发现是乳头层和真皮中层的炎症和瘢痕形成，皮下脂肪中的毛囊几乎完全未受影响。通过手术切除这两个区域实现了成功治疗。有人认为，簇状区域代表了发生炎症和瘢痕形成的痣样病变。
