Alopecic and aseptic nodules of the scalp (AANS) is a rare entity, etiology of which is already unknown. It consists of a few dome-shaped, skin-colored nodules associated with nonscarring alopecia. They are usually located in the upper part of the occiput and surrounded by normal scalp. Most of the times, a biopsy is performed to make an accurate diagnosis. AANS have a good prognosis and even can resolve spontaneously. We present a new case of this entity with the description of trichoscopic and ultrasonographic findings that have recently been reported. These noninvasive techniques are useful for the diagnosis and could replace histological examination in the near future.
头皮秃发性无菌性结节（AANS）是一种罕见病症，其病因尚不明确。它由几个圆顶状、肤色结节组成，并伴有非瘢痕性脱发。这些结节通常位于枕部上方，周围是正常头皮。大多数情况下，需进行活检以做出准确诊断。AANS预后良好，甚至可自行消退。我们报告了该病症的一例新病例，并描述了最近报道的毛发镜和超声检查结果。这些非侵入性技术对诊断很有用，在不久的将来可能会取代组织学检查。
