据我们所知，这是第二例有关发疹性毳毛囊肿的报告。皮损发生在一名 18 岁女性身上，由胸部前部 35 至 40 个 1 至 4 毫米的棕黑色丘疹组成。组织学上，病变由真皮中部的小囊肿组成，其中含有层状和无定形角质材料和毳毛。囊肿壁由几层鳞状上皮组成，其外部附着有一个未发育的卵泡。十个月后，病变自然消退。发病机制尚不清楚，但这种情况似乎是一种新的独特实体。 (Arch Dermatol 115:744-746, 1979)
This is, to our knowledge, the second report of eruptive vellus hair cysts. The lesions, which occurred in an 18-year-old woman, consisted of 35 to 40 brownishblack, 1- to 4-mm papules on the anterior aspect of the chest. Histologically, the lesions consisted of small cysts in the middle dermis that contained laminated and amorphous keratinous material and vellus hairs. The cyst wall consisted of several layers of squamous epithelium with a rudimentary follicle attached to its outer aspect. The lesions regressed spontaneously after ten months. The pathogenesis is obscure but the condition appears to be a new distinctive entity. ( Arch Dermatol 115:744-746, 1979)
