Oral and dermatologic lesions observed in mild COVID‐19 patients infected after 3rd vaccine dose

New onset and exacerbation of oral lichenoid mucositis following SARS‐CoV‐2 infection or vaccination

“…Following the description of coronavirus disease 2019 (COVID‐19) and its causative agent severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), case reports of oral mucosal reactions to SARS‐CoV‐2 infection have been published (Amorim Dos Santos et al, 2021; Brandão et al, 2021; da Mota Santana et al, 2022; Fidan et al, 2021; Iranmanesh et al, 2021), including new onset or exacerbation of OLP/LM following SARS‐CoV‐2 infection or vaccination (Burgos‐Blasco et al, 2021; Diaz‐Guimaraens et al, 2021; Fidan et al, 2021; Sharda et al, 2021; Troeltzsch et al, 2021). Here, we report OLP/LM in three categories (Table 1): 1) new‐onset OLP/LM following COVID‐19 infection (case 1), 2) new‐onset OLP/LM following COVID‐19 vaccination (cases 2 and 3), and 3) exacerbation of known OLP/LM following vaccination (cases 4–7).…”

SARS‐CoV‐2 is capable of reactivating orocutaneous opportunistic infections in vaccinated patient: A case report

“…Letter to the Editor, During the COVID-19 crisis, several cases of oral and cutaneous lesions were reported by different authors. 1,2 Despite a vast literature being produced in the last years since the outbreak, the disease pathogenesis remains complex up until this day. The emergence of variants of interest (VOCs) of the novel coronavirus such as the Omicron variant (B.1.1.529) and its respective lineages may also represent a challenge to vaccine-induced immunity.…”

“…The emergence of variants of interest (VOCs) of the novel coronavirus such as the Omicron variant (B.1.1.529) and its respective lineages may also represent a challenge to vaccine-induced immunity. 2 Here, we report a case of a patient with the complete vaccination schedule, including fourth boost dose and subsequent exacerbation of herpes zoster (HZ) symptoms jointly with orocutaneous eruptions after a second infection by SARS-CoV-2.…”

Persistent erythematous candidiasis as a sequela after SARS‐CoV‐2 infection: A case report

“… 1 , 2 Although most cases had occurred in phases before vaccination, immunized patients as well may be affected. 3 More than 2 years after being declared a pandemic by the WHO, the pathogenicity mechanism of the new coronavirus has not been fully elucidated, however, an intrinsic relationship with ACE‐2 receptors has been established. 4 Interestingly, oral tissues show a high concentration of this protein that justifies the presence of the pathogen in the saliva and subsequent transmission through droplets and aerosols.…”
