Palmoplantar lichen planus is a rare variant of lichen planus with diverse clinical presentations, making the diagnosis challenging. We present an unusual case of a young patient who presented with asymptomatic non-pruritic flat-topped pigmented plaques on his left sole and no other lesions elsewhere. Histology was consistent with lichen planus. We emphasize a high index of suspicion owing to varied clinical presentation and the necessity of a biopsy for diagnosis
