CASE PRESENTATION
A 30 years old lady with no co-morbidities and no significant past
medical history. She received her third booster dose of mRNA-1273
COVID-19 vaccine 5 days before presenting with symptoms.
The initial symptom was a mild dry cough. On the second day, she
developed a pruritic, erythematous macular rash on the back of her neck
and the volar aspect of her forearms. She did not self-medicate with
over-the-counter (OTC) medications and sought medical attention on an
outpatient basis. On evaluation, she was found to be COVID-19 Antigen
positive and was prescribed antihistamines.
On the fourth day of symptoms, she presented to the ED (emergency
department) with a worsening pruritic rash which had spread to involve
her neck, face, arms, trunk, and legs (Figures
1-3)
and mild fever, and dyspepsia.
She did not have shortness of breath, stridor, wheeze, chest pain, or
abdominal pain. She had no history of insect bites, exposure to new
foods, recent use of any medications, over-the-counter medications,
herbal supplements, and no known disease exposures. The patient denied
any past history of similar rashes or allergic reactions and also denied
any family history of the similar condition or skin diseases running in
her family.
