Hypertrophic lichen planus (HLP) is a chronic variant of lichen planus with an estimated risk of 0.4% developing squamous cell carcinoma (SCC) in later years. We report the case of a 12-year- old boy with history of hypertrophic lichen planus since 4 years of age, with malignant transformation into squamous cell carcinoma along with lymph node metastasis.

Chronic graft-versus-host disease (cGVHD) and oral lichen planus (LPO) are chronic inflammatory conditions with similar oral manifestations. This study aimed to assess whether serum and salivary cytokines (IL-1α, IL-6, IL-17) could serve as reliable biomarkers for cGVHD. A prospective cohort study was conducted involving cGVHD patients, LPO patients, and healthy controls.

Our study aimed to establish the basic reliability parameters of direct immunofluorescence test results in patients with oral lichen planus. We conducted an evaluation of individual antibody classes in the DIF and ELISA (BP180 antigen), comparing these results with the classical histopathological (HP) examination in a group of patients treated within the standard healthcare in our clinic. Among 66 participants with oral changes indicative of LP, only 50% received histopathological confirmation of the LP diagnosis.

Background: Lichen planus (LP), an autoimmune disorder, remains incompletely understood in terms of its etiological mechanisms. This study aims to elucidate causal relationships among immune cell populations, plasma metabolites, and lichen planus using Mendelian randomization (MR) techniques.
Methods: Employing a two-sample, two-step MR approach, with single nucleotide polymorphisms (SNP) serving as genetic instruments for both exposures and mediators, this study minimizes biases from confounding and reverse causality.

Injectable platelet-rich fibrin (i-PRF) is a novel platelet concentrate that has been employed in dentistry with the objective of promoting tissue regeneration and healing. In contrast to platelet-rich plasma (PRP), i-PRF is more straightforward to handle, more cost-effective, and free from anticoagulants, which reduces biochemical alterations. The i-PRF procedure was developed in 2014 by adjusting the centrifugation forces.
