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,

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
