A 50-year old woman with hyperkeratotic verrucous papules and plaques visited the outpatient clinic of Dermatology. Histopathology showed hyperplasia of verrucous epithelia, orthokeratosis and an infiltrate, leading to the diagnosis 'verrucous (hypertrophic) lichen planus'. This skin condition is often misdiagnosed as psoriasis. Squamous cell carcinoma can develop within skin lesions.
