Lichen planus secondary to rabies vaccination

Lichen planus following SARS‐CoV‐2 infection and vaccination? A systematic review

“…Lichen planus (LP) is a self‐limiting, idiopathic mucocutaneous inflammatory disease with clinical subtypes, characterized by pruritic violaceous papules favoring the extremities. 1 , 2 LP has been previously associated with viruses ( e.g . Hepatitis C) and vaccinations ( e.g .…”

“…Hepatitis C) and vaccinations ( e.g . Hepatitis B and C, influenza, DTaP‐IPV‐MMR), 1 , 2 and specifically recently, SARS‐CoV‐2 infection/vaccination. Cases of other autoimmune dermatologic conditions following SARS‐CoV‐2 infection/vaccination have been comprehensively summarized, 3 but cases of LP have not.…”

“…The relationship between viruses/vaccinations and LP is unknown. 2 However, the proposed pathophysiology includes virus/vaccine‐induced cell‐mediated autoimmunity or molecular mimicry. 2 Drug/vaccine‐induced LP and classical LP appear identical with regards to location and morphology and cannot be differentiated histologically.…”

“… 2 However, the proposed pathophysiology includes virus/vaccine‐induced cell‐mediated autoimmunity or molecular mimicry. 2 Drug/vaccine‐induced LP and classical LP appear identical with regards to location and morphology and cannot be differentiated histologically. 4 The two subtypes are typically only differentiated based on whether a history of recent vaccine or drug exposure is present.…”

Linear IgA bullous dermatosis after COVID‐19 vaccination

“…All cases of LABD were diagnosed using direct immunofluorescence. [2][3][4][5] As of October and LABD in one case was complicated by the use of oral terbinafine 12 days before onset. 2 One post-Spikevax case resembled toxic epidermal necrolysis in clinical presentation 2 while another post-Spikevax case resembled bullous pemphigoid in histopathological presentation.…”
