This is the first American report, to our knowledge, of a case of acne aestivalis, which occurred in a woman with a recurrent acneform eruption in summertime. The histopathologic sequence was very similar to that found in cases of steroid acne; namely, local necrosis of the follicular epithelium was followed by the formation of a comedo. No cause was found. Treatment with tretinoin brought about regression of the lesions.
据我们所知，这是美国首例夏季痤疮的报告，患者为一名女性，夏季反复出现痤疮样皮疹。组织病理学变化过程与类固醇痤疮非常相似；即毛囊上皮局部坏死，随后形成粉刺。未发现病因。外用维甲酸治疗使皮损消退。
