Of 11 patients with eruptive vellus hair cysts, seven were between ages 17 and 24 years when the dermatosis first appeared. The sites of predilection were mainly the anterior part of the chest and the extremities, though the lesions were also seen on the face, neck, axilla, and groin. In some lesions that regressed spontaneously, the cysts were connected to the surface, forming an opening pore. In other lesions, the cystic material formed foreign-body granulomas by degradation of the cyst walls.
在11例发疹性毳毛囊肿患者中，7例在皮肤病首次出现时年龄在17至24岁之间。好发部位主要是胸部前部和四肢，不过在面部、颈部、腋窝和腹股沟也可见到病变。在一些自行消退的病变中，囊肿与表面相连，形成一个开口小孔。在其他病变中，囊内容物通过囊肿壁的降解形成异物肉芽肿。
