The prevalence of LP is almost 0.89% of the population, and it commonly affects middle-aged individuals of both genders. The pathogenesis and aetiology of the disease are not completely known. 1 LP is a T cell-mediated auto-inflammatory disease. In pathogenesis, T cell activation acts a significant role. Activated T-cells induce the T helper type 1 (Th1) response. 2 An inflammatory response caused by Th1 cytokines (IL-2, 4, 6, 10) and TNFα also acts a role in the pathogenesis of metabolic syndrome. 3 Dyslipidaemia, which is one of the metabolic syndrome components, has been found to be associated with LP. Chronic inflammation is the main factor in its relationship with dyslipidaemia in patients with LP. 3 The relationship of chronic inflammatory skin diseases with MS has been more clearly demonstrated in recent years. 3 Again, in this context, the number of publications showing the relationship with MS in lichen planus patients has increased. 1,4 Acanthosis nigricans is a clinical finding described by asymptomatic plaques that are grayish-brown or black in color, raised from the skin, lichenified, velvety, and violase, with no sharp borders, located in intertriginous areas such as axilla, neck, and groin. 5 Hyperkeratosis and papillomatosis are prominent in histopathological examination. 5
