Lichen planus is a mucocutaneous disease that can cause various manifestations, such as itchy erythematous papules, cicatricial alopecia, erosion, and mucocutaneous ulcers. One uncommon manifestation of this disease is the occurrence of erosion and skin ulcers in the soles of the feet, which can cause many problems for patients. Tofacitinib, a Janus Kinase (JAK) inhibitor drug, has found a special place in the field of inflammatory diseases, especially inflammatory skin diseases. In this regard, studies on the effective role of this drug in the treatment of certain forms of lichen planus, including lichen planopilaris, and erosive lichen planus have been performed. In upcoming study, we introduce a 52-year-old woman with lichen planus who complained of ulcerative lesions on the sole of her foot, for whom a diagnosis of plantar ulcerative lichen planus was proposed. After the patient did not respond therapeutically to intralesional triamcinolone acetonide injection, as well as methotrexate and cyclosporine tablets, significant improvement was finally achieved with a 5 mg twice daily dose of tofacitinib. In the following, we will comprehensively review previous articles on the role of tofacitinib in the treatment of lichen planus lesions, as well as the proposed treatment options for erosive and ulcerative lichen planus lesions specifically located on the sole of the foot. Despite limited reports of the successful treatment of mucosal erosive lesions in the oral, esophageal, genital, and ocular mucosa areas with tofacitinib, no previous study has reported the successful treatment of ulcerative lichen planus lesions of the plantar area with tofacitinib. While reporting this case, we recommend considering tofacitinib as a treatment option for plantar ulcerative lichen planus. To confirm its effectiveness, it is necessary to conduct more extensive studies with a larger sample size.
