We report the first case to our knowledge of monolateral Favre-Racouchot syndrome (FRS) following long-term exposure to infrared waves.

A 63-year-old man was referred for a 10-year history of papules and nodules exclusively on the left malar region, treated previously with topical retinoid therapy without improvement. The patient was otherwise healthy, had been smoking 20 cigarettes per day for 40 years, and worked as an engraver. In his capacity as an engraver, he had been exposed for several hours a day over the course of more than 40 years to the light of an incandescent lamp, kept always on his left side, to illuminate his field of work.

长期暴露于红外线下的单侧Favre-Racouchot综合征

在长期暴露于红外线后，我们报告了第一例单侧Favre-Racouchot综合征（FRS）的知识。

一名63岁的男性因仅在左黄斑区有10年的丘疹和结节病史而被转诊，此前曾接受过局部类维生素A疗法治疗，但无改善。该患者原本是健康的，每天抽20支烟已有40年，并担任雕刻师。在担任雕刻师一职的过程中，在40多年的时间里，他每天要暴露于几个小时的白炽灯下，照亮他的工作领域，白炽灯始终放在他的左侧。
