Vaccines are indeed a boon for tackling the present COVID‐19 pandemic. In India, ChAdOx1 nCoV‐19 (Covishield) is the most commonly used vaccine in the government vaccination program for adults more than 18 years of age. It is a recombinant vaccine developed by Oxford‐Astra Zeneca and manufactured in India by Serum Institute of India (SSI). Here, we report a case of severe pemphigus vulgaris following the second dose of ChAdOx1 nCoV‐19 vaccination in an adult male. The patient developed septicemia during the course of hospital stay, and he was managed with systemic steroids, parenteral antibiotics, and intravenous immunoglobulins (IVIg) along with proper wound care. Patient started improving within 1 month of therapy. This case is being reported in view of the rarity of pemphigus vulgaris following ChAdOx1 nCoV‐19 vaccine.
Background:
There have been increasingly reported cases of new-onset or aggravation of pre-existing dermatoses after the implementation of COVID-19 vaccination.
Case Presentation:
An elderly male presented with multiple annular scaly plaques all over the body two weeks following administration of the first dose of Oxford-AstraZeneca COVID-19 vaccine. The lesions further aggravated after taking the second dose of the vaccine. The clinical and histopathology features were suggestive of annular plaque psoriasis.
Conclusion:
We report this first case of de novo plaque psoriasis following the Oxford-AstraZeneca COVID-19 vaccine, and it signifies a potential side effect of autoimmune reactivation after COVID vaccination.
Blastomycosis-like pyoderma (BLP) is an uncommon tissue response possibly to bacterial infection that presents as vegetative skin lesions usually in immunocompromised patients. Staphylococcus aureus is the most frequent pathogen implicated in BLP. Here, we report the case of a 32-year-old man who had ulcerative vegetating lesions on extremities for 3 months over preexisting recalcitrant tinea lesions. The patient was hypertensive with a history of chronic graft rejection after renal transplantation 8 months earlier and was on long-term immunosuppressants. Investigations revealed anemia, mild hyperglycemia, and elevated serum creatinine. Histopathology showed suppurative and fibrosing perifolliculitis with moderate pseudocarcinomatous hyperplasia and the culture of biopsy specimen demonstrated growth of Escherichia coli and Citrobacter koseri. The diagnosis of BLP overlying dermatophytoses was made. The skin lesions improved completely with parenteral antibiotics. Local immune dysregulation by dermatophytoses along with iatrogenic immunosuppression may have favored this rare pyoderma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
