Introduction
Radiation Recall Phenomenon (RRP) is an inflammatory disorder triggered by some medications and physical agents at the site of previous irradiation. This phenomenon is reported in the skin and other organs, like lung, muscle, and intestine, and is mainly precipitated by anti-cancer medications; however, other drugs can also induce RRP (e.g., some antibiotics, statins, letrozole, tamoxifen). 1, 2
Recently a few cases of RRP have been reported after different types of COVID-19 vaccine in the skin and lung. 3-5
Here, we report a case of radiation recall dermatitis after inactivated SARS-CoV-2 vaccine (Sinopharm, China), repeated after rechallenge in the second dose of vaccine.
