Recurrent Painful Abdominal Rash

To assess the incidence and risk factors for chronic radiodermatitis after FGI in high-risk patients. Materials and methodsBetween 2010 and 2016, among 55,782 patients who underwent FGI, 359 had a risk procedure for skin injury (maximal skin dose > 3 Gy, air kerma > 5 Gy, dose area product (DAP) >500 Gy.cm 2 or fluoroscopy time > 60 minutes). Ninety-one of them were examined by a dermatologist for radiodermatitis (median time after procedure 31.2 months (95%IC [14.2-50.7]). In each case, the clinical features and topography of the skin lesions were recorded and their incidence calculated. The characteristics of the patients and of the FGI were tested as risk factors. ResultsEight patients (8.8%) had chronic radiodermatitis and 19 (20.9%) acute radiodermatitis. BMI, the DAP value and air kerma were the only risk factors identified. ConclusionThis study shows that chronic radiodermatitis may be considered as a frequent side effect in an at-risk population. The lesions are commonly benign but extensive sclerosis can occur. Patients should be better informed about the side effects and offered a skin exam periodically.

Although radiation dermatitis is a widely known complication of radiotherapy, its association with fluoroscopy-guided interventional procedures is yet under recognized. We present a case of a 66-year-old man with a left scapular cutaneous lesion, initially diagnosed as a fixed drug eruption. The subsequent knowledge of a previous percutaneous aortic paravalvular leak closure procedure allowed a correct clinicopathological correlation and the final diagnosis of subacute radiodermatitis associated with fluoroscopy. Many of the patients with skin injury associated with fluoroscopic procedures do not associate both and seek physicians other than the one who performed the procedure. Besides interventional physicians, dermatologists and other physicians should be aware of this form of radiation injury and its manifestations. Suspicion and active search for a history of previous fluoroscopic procedures in patients with figurate cutaneous lesions in allusive locations may allow the diagnosis of this potentially serious complication that should have long follow-up due to the possibility of long-term side effects.
