Subacute cutaneous lupus (SCLE) flare after COVID-19 immunization; Four days after vaccination, she noticed worsening of SCLE lesions, characterized by increased pruritis, burning and erythema.; This literature-non-study case was reported in a literature article and describes the occurrence of SUBACUTE CUTANEOUS LUPUS ERYTHEMATOSUS (Subacute cutaneous lupus (SCLE) flare after COVID-19 immunization) in a 54-year-old female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.      The patient's past medical history included Subacute cutaneous lupus erythematosus (autoimmune skin diseases may worsen after COVID-19 vaccination). Concurrent medical conditions included Rash (Patient presented with 9 months of a rash on her face, neck, trunk and extremities consistent with SCLE, based on clinicopathological correlation). Concomitant products included HYDROXYCHLOROQUINE for an unknown indication.   On an unknown date, the patient received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date, received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On an unknown date, the patient experienced SUBACUTE CUTANEOUS LUPUS ERYTHEMATOSUS (Subacute cutaneous lupus (SCLE) flare after COVID-19 immunization) (seriousness criterion medically significant) and CONDITION AGGRAVATED (Four days after vaccination, she noticed worsening of SCLE lesions, characterized by increased pruritis, burning and erythema.). The patient was treated with MYCOPHENOLATE MOFETIL for Subacute cutaneous lupus erythematosus, at a dose of 500 milligram twice a day; MYCOPHENOLATE MOFETIL for Subacute cutaneous lupus erythematosus, at a dose of 1000 milligram twice a day; MYCOPHENOLATE MOFETIL for Subacute cutaneous lupus erythematosus, at a dose of 1500 milligram twice a day and TRIAMCINOLONE for Subacute cutaneous lupus erythematosus, at an unspecified dose and frequency. At the time of the report, SUBACUTE CUTANEOUS LUPUS ERYTHEMATOSUS (Subacute cutaneous lupus (SCLE) flare after COVID-19 immunization) and CONDITION AGGRAVATED (Four days after vaccination, she noticed worsening of SCLE lesions, characterized by increased pruritis, burning and erythema.) was resolving.
