11 Although the exact etiology of lichen planus is unknown, an immune-mediated pathogenesis is recognized.1 A meta-analysis of primarily case-control studies conducted in multiple countries found a statistically significant association between hepatitis C virus (HCV) infection and lichen planus,3 although there is no known explanation for this association. Compared with the control group, patients with lichen planus had a greater prevalence of HCV exposure (odds ratio = 5.4; 95% confidence interval, 3.5 to 8.3), and patients with HCV infection had an increased prevalence of lichen planus (odds ratio = 2.5; 95% confidence interval, 2.0 to 3.1).3 It is appropriate to screen all patients with lichen planus for HCV infection.4 Patients should be asked about HCV risk factors, and liver enzyme and HCV antibody tests should be ordered.

È difficile costruire un chiaro quadro clinico, poiché il lichen ruber planus non si manifesta con le medesime lesioni cutanee in ogni paziente: le papule tipiche della malattia possono presentare forma, dimensioni, localizzazione e disposizione diverse, rendendo talvolta intricato il riconoscimento della malattia.
It is a 5-methylcytosine RNA methyltransferase [75]. Binding of this protein to mitochondrial transcription termination factor 4 (MTERF4) is crucial for ribosome biogenesis which is critical for oxidative phosphorylation capacity. Biogenesis of mammalian mitochondrial ribosomes requires a maturation of both the small and large ribosomal subunit and NSUN4 in complex with MTERF4 is required to assemble the small and large subunits to form a monosome [76].

There are four forms of oral lichen planus: reticular, atrophic, bullous, and erosive.6 The reticular form is most common and manifests as bilateral, asymptomatic Wickham striae on the oral mucosa (Figure 8) or other parts of the mouth, such as the gingiva, tongue, palate, and lips (Figure 95). The atrophic form causes atrophic changes with erythema of the oral mucosa. The bullous form manifests as fluid-filled vesicles. The erosive form leads to ulcerated, painful, erythematous areas that may contract secondary infection, such as candidiasis. These ulcerated areas may have Wickham striae and occur in one or multiple sites of the mouth. Erosive lichen planus of the gums resembles desquamative gingivitis. Malignant transformation has been reported in men with oral erosive lichen planus lesions.10

It appears as raised, many-sided purple bumps (violaceous polygonal papules) with overlying white lines (Wickham’s striae). It commonly involves the wrists (flexor surface), lower back (lumbar region), shins, and ankles. The lesions often itch. Females are more frequently affected than males and the age range is approximately 30 to 60 years of age. This is a less common variant, shown here with scales.

    Esophageal lichen planus, affecting the esophageal mucosa. This can present with difficulty or pain when swallowing due to oesophageal inflammation, or as the development of an esophageal stricture. It has also been hypothesized that it is a precursor to squamous cell carcinoma of the esophagus.[10][31]
