Case report:
A 66-year-old female, with a history of arterial hypertension, was
admitted to the infectious diseases department for vesicular eruption
associated with a severe pain on her right side of the face. She
reported that she received her first dose of AstraZeneca COVID-19
vaccine 5 days ago. No other symptoms such as fever, dyspnea or cough
were accompanied. The physical examination revealed: a temperature of 37
°C, heart rate 92 beats per minute, respiratory rate 16 breaths per
minute, blood pressure 120/70 mmHg and Glasgow coma score of 15. The
vesicular lesions contained purulent fluid upon an erythematous base and
were localized in the right cheek, side of nose and upper lip,
associated with palpebral edema (Figure1). The oral mucosa was intact.
The biological findings of the serum showed: blood cell counts, renal
and hepatic functions within normal limits and an elevated c-reactive
protein (35 mg/L). The serological tests of Human Immunodeficiency Virus
(HIV) 1 and 2 were negative. The patient didn’t report the use of
immunosuppressive drugs or coticosteroid therapy, a history of
malignancy, physical trauma or psychological stress. The diagnosis of

presentaton of the lesions. Antiviral treatment was started with
acyclovir 750mg thrice daily for 10 days associated with antibiotic
treatment: amoxicillin-clavulanic acid 1gr three times a day for a week
to treat the bacterial superinfection. The outcome was favourable unless
