The purpose of this study is to compare the efficacy and safety of two standard corticosteroid treatments for hypertrophic lichen planus (HLP), a chronic inflammatory skin condition that causes thick, intensely itchy plaques.
Patients participating in the study will be randomly assigned to one of two treatment groups:
* Group A will apply a superpotent topical steroid cream (Clobetasol propionate 0.05%) to their lesions twice daily for 12 weeks.
* Group B will receive intralesional injections of a steroid medication (Triamcinolone acetonide 10 mg/mL) directly into the lesions once every 4 weeks for a total of four sessions over 12 weeks.
The primary objective is to determine which approach achieves a better reduction in plaque thickness and severity using the Lichen Planus Severity Index (LPSI) score at week 12. The study will also track changes in itching severity using a Visual Analog Scale (VAS), changes in overall lesion surface area, and monitor for any local side effects such as skin thinning or pigment changes.
