New-onset cutaneous lupus erythematosus after the COVID-19 vaccine.

Vaccine development for COVID-19 has progressed expeditiously. To date, the Food and Drug Administration (FDA) has authorized the Moderna/mRNA-1273, Pfizer-BioNTech (BNT162b2), and Johnson & Johnson's Janssen (JNJ-78436735) vaccines for use in the United States. Immediate side effects have included myalgia fatigue, chills, fever, and headache. We report an elderly patient with a history of lung cancer and no prior history of autoimmune disease who developed cutaneous lupus erythematosus two ½ months after the second dose of the Pfizer-BioNTech COVID-19 vaccine.
