Fluoroscopy-induced chronic radiation dermatitis (FICRD) resulting from prolonged exposure to ionizing radiation during interventional procedures has been documented in the radiology and cardiology literature. However, the phenomenon has been rarely reported in the dermatologic literature. Since patients with FICRD often see a dermatologist or a primary care physician to treat their injuries, the diagnosis of FICRD is perhaps often overlooked.
A 62-year-old man with type 2 diabetes mellitus and severe coronary artery disease was seen with a 2-year history of a pruritic, tender, telangiectatic patch lesion over his left scapula. Over the next 2 years, the lesion became indurated and eventually ulcerated. A skin biopsy specimen demonstrated changes consistent with a chronic radiation dermatitis. The patient was unaware of radiation exposure, but persistent questioning from his dermatologists revealed that he had undergone multiple fluoroscopy-guided cardiac procedures. This was confirmed by a review of his medical records.
The diagnosis of FICRD should be considered for any patient who is seen with an acquired vascular lesion, a morphealike lesion, or an unexplained ulcer localized over the scapula, the back, or lateral trunk below the axilla.
介入手术期间因长期暴露于电离辐射而导致的荧光透视诱发的慢性放射性皮炎(FICRD)已在放射学和心脏病学文献中有所记载。然而,这一现象在皮肤病学文献中鲜有报道。由于FICRD患者常因皮肤损伤就诊于皮肤科医生或初级保健医生,FICRD的诊断可能常被忽视。
一名62岁的2型糖尿病和严重冠状动脉疾病男性患者,左肩胛骨处出现瘙痒、触痛的毛细血管扩张性斑片状损害,病史2年。在接下来的2年里,该损害变硬,最终发生溃疡。皮肤活检标本显示出与慢性放射性皮炎相符的变化。患者不知道自己曾接触过辐射,但皮肤科医生不断追问后发现他曾接受过多次荧光透视引导下的心脏手术。查阅他的病历证实了这一点。
对于出现后天性血管性损害、硬斑病样损害或肩胛区、背部或腋窝以下侧胸壁不明原因溃疡的任何患者,均应考虑FICRD的诊断。
