A case of hyperkeratosis lenticularis perstans involving only the back of a thirty-nine-year-old woman is reported. Histologic examination showed foci of compact and eosinophilic hyperkeratosis overlying a thinned stratum malpighii. In the underlying papillary dermis there was no evidence of inflammatory infiltrate. This case demonstrates that hyperkeratosis lenticularis perstans may appear as a localized disorder, and that the inflammation is not an essential pathogenic process in this disorder.
报告了一例仅累及一名39岁女性背部的持久性豆状角化过度症病例。组织学检查显示，致密性嗜酸性角化过度灶覆盖在变薄的马尔皮基层之上。在其下方的乳头层真皮中，没有炎症浸润的迹象。该病例表明，持久性豆状角化过度症可能表现为一种局限性疾病，并且炎症并非该疾病的必要致病过程。
