Lichen planus (LP) is a fairly distinctive mucocutaneous disease. The etiology of the condition appears to be complex and multifactorial, with unique histopathological features. Immunofluorescence studies have provided some insight into a proposed immunopathogenesis. LP is seen frequently in the middle-aged and elderly population. The female-to-male ratio is approximately 2:1. Children are rarely affected. The incidence of oral LP in children is reportedly high among Asians. We present a 9-year-old Indian child with the documented clinical aspects, histopathology and immunofluorescence studies.

Aim: This study aimed to evaluate the effectiveness of fenugreek as an adjuvant in managing oral potentially malignant disorders (OPMDs), specifically leukoplakia, lichen planus, and oral submucous fibrosis (OSMF).
Materials And Methods: Twenty-one participants prediagnosed with OPMDs were randomly divided into a study group (SG) and a control group (CG), with 10 participants in SG and 11 in CG, respectively. The SG received 2 gm of fenugreek as an adjuvant with standard systemic treatments tailored to the respective lesions: intralesional injection of vitamin A 1,00,000 IU (Aquasol A) and topical application of triamcinolone acetonide 0.

Background/purpose: Oral lichen planus (OLP) is a chronic inflammatory disorder characterized by basement membrane disruption, which plays a crucial role in its pathogenesis. Matrix metalloproteinases (MMPs), a group of proteolytic enzymes, contribute to the degradation of the basement membrane. The specific MMPs secreted by keratinocytes in OLP lesions and relevant regulatory mechanisms are not fully understood.
