The term acne mechanica designates local exacerbations due to pressure, friction, rubbing, squeezing, or stretching. Examples are given of various physical traumata that provoke lesions in acne patients. The precipitating causes of stress are diverse, they include articles of clothing (tight straps and belts), recreational accouterments (football shoulder pads), or occupational pressure (rubbing of back in truck drivers). Sealing acne-bearing skin under adhesive for two weeks regularly induced new inflammatory lesions, which derived from the rupture of microcomedones that are not visible to the naked eye.
机械性痤疮这一术语指因压力、摩擦、揉搓、挤压或拉伸导致的局部病情加重。文中给出了各类致使痤疮患者出现皮损的物理创伤实例。引发此类情况的原因多种多样,包括衣物(紧身束带和腰带)、娱乐装备(橄榄球护肩)或职业压力(卡车司机背部受到摩擦)。用粘合剂定期密封长有痤疮的皮肤两周会经常引发新的炎性皮损,这些皮损源自肉眼不可见的微粉刺破裂。
