Generalized erythrodermic psoriasis triggered by vaccination against severe acute respiratory syndrome Coronavirus 2.

Generalized erythrodermic psoriasis (GEP) is a rare and potentially life‐threatening variant of psoriasis. Possible triggers that have been identified to date include poorly controlled psoriasis, medications, abrupt discontinuation of anti‐psoriatic treatment, and underlying systemic illnesses. However, vaccines have rarely been reported to exacerbate GEP. Herein, we report two unique cases with GEP exacerbated following a dose of the BNT162b2 mRNA vaccine for COVID‐19 (as their second dose, the first being the mRNA‐1273 vaccine). Based on our observations and a literature review, vaccination was considered the most likely trigger of GEP due to the close temporal relationship between the second vaccination and the onset of GEP.
