Objectives Previous studies have shown that patients with lichen planus (LP) have an increased occurrence of inflammation-related dyslipidemia. Although classic cutaneous LP (CCLP) and oral LP (OLP) are basically known as the different subtypes of the same disease sharing the common histopathological features, they actually have significant differences both in the clinical behavior and in the molecular inflammatory pathogenesis. We aimed to compare the lipid profile of patients with CCLP and OLP. Materials and methods This study included 120 patients, 30 with isolated CCLP, 30 with isolated OLP, 30 with CCLP + OLP, and 30 controls consecutively admitted to the outpatient clinics of Dermatology Department of Dokuz Eylul University Hospital, Izmir, Turkey. Results Triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) values, TC/high-density lipoprotein cholesterol (HDL-C), and LDL-C/HDL-C atherogenic indexes were significantly higher, and HDL-C values were significantly lower in all LP subtypes compared with the controls. Among LP subtypes, although the differences were not statistically significant, TG, TC, and LDL-C values were markedly higher in OLP and OLP + CCLP patients compared with CCLP patients. OLP and CCLP + OLP patients also showed significantly higher TC/HDL-C and LDL-C/HDL-C atherogenic indexes compared with CCLP patients. Conclusions Patients with OLP have a more impaired lipid metabolism and significantly higher atherogenic indexes compared with patients with CCLP. The differences in the molecular inflammatory pathways between OLP and CCLP and the longer disease duration of OLP leading to long-lasting inflammation may elucidate this distinction.
