Psoriasis is a chronic papulosquamous disorder with rare involvement of oral mucosa and no definite clinical or histopathological criteria for oral psoriasis.

A 32-year-old male, a mason by occupation, presented with complaints of itchy scaly lesions on hands and lips for 4 years and 6 months, respectively, and pain over the small joints of the hands for 6 months. History of winter exacerbation was present with symptomatic relief on using topical steroids.

Erythematous plaques with fissuring and scaling were noted on both the lips extending onto the vermilion border. Oral cavity examination revealed fissuring of the tongue.
