Two cases of palmoplantar lichen planus with various clinical features. Palmoplantar lichen planus is a rare, localized variant of lichen planus. Although several clinical features of palmoplantar lichen planus may be seen, the erythematous scaly form is most common. We present two cases of palmoplantar lichen planus that show vesicle-like and petechia-like features, which are uncommon variants of palmoplantar lichen planus.

    ABSTRACT: Lichen planus (LP) is a chronic inflammatory skin disease characterized by polygonal, violaceous papules commonly involving flexural areas of the wrists, legs, and oral and genital mucous membranes. This report describes a patient who presented with asymptomatic black colored patches on both palms simulating Tinea nigra, a superficial fungal infection. She was previously diagnosed as allergic contact dermatitis and was being treated with potent topical steroid i.e. clobetasol propionate 0.05% and white soft paraffin. Dermatoscopy of the lesion showed brownish pigmentation along ridges of the dermatoglyphics. A biopsy from the lesional skin showed findings of lichen planus. Our case highlights the potential diagnostic confusion that can occur with unusual variants of palmoplantar lichen planus and importance of histopathology in diagnosis of such unusual lesions.

    ABSTRACT: Lichen planus (LP) is a chronic inflammatory disorder that most often affects middle-aged adults. LP can involve the skin or mucous membranes including the oral, vulvovaginal, esophageal, laryngeal, and conjunctival mucosa. It has different variants based on the morphology of the lesions and the site of involvement. The literature suggests that certain presentations of the disease such as esophageal or ophthalmological involvement are underdiagnosed. The burden of the disease is higher in some variants including hypertrophic LP and erosive oral LP, which may have a more chronic pattern. LP can significantly affect the quality of life of patients as well. Drugs or contact allergens can cause lichenoid reactions as the main differential diagnosis of LP. LP is a T-cell mediated immunologic disease but the responsible antigen remains unidentified. In this paper, we review the history, epidemiology, and clinical subtypes of LP. We also review the histopathologic aspects of the disease, differential diagnoses, immunopathogenesis, and the clinical and genetic correlations.
