Lichen Planus Erythematosus

Lichen planus in Germany – epidemiology, treatment, and comorbidity. A retrospective claims data analysis

“…For OLP, a female predominance has been reported [23][24][25]. The age of manifestation typically lies between 50 and 60 for OLP and between 40 and 45 for cutaneous LP [19,23]. Therefore, the results from the present study are in line with those reported in previous epidemiological analyses.…”

The Impact of COVID-19 Vaccination on Inflammatory Skin Disorders and Other Cutaneous Diseases: A Review of the Published Literature

“…Lichen planus (LP) is an inflammatory disease involving the skin and mucous membranes with no known cause. The lesions are pruritic, purplish papules and plaques that are mostly located on the wrists, back, and ankles [ 74 ]. To date, to the best of our knowledge, 13 cases of new onsets of the disease have been reported in the literature [ 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 ], while worsening of lichen planus after COVID-19 vaccination has been reported in three cases [ 84 , 85 , 86 ].…”

A Molecular Hypothesis on Malignant Transformation of Oral Lichen Planus: A Systematic Review and Meta-Analysis of Cancer Hallmarks Expression in This Oral Potentially Malignant Disorder

“…Our study, however, has some limitations among which is the absence of primary-level studies that focus on the analysis of cancer markers in OLP cases that have undergone malignant transformation and compare with non-malignant cases; furthermore, although very interesting, it was not possible to explore through stratified meta-analyses the influence of relevant potential risk factors, such as smoking, gender, and age of patients, clinical appearance of lesions, among others, and consequently, there are studies based on heterogeneous cases of OLP [162,163]. Unfortunately, these analyses could not be performed due to the failure to report individual participant data across the included primary-level studies.…”
