Oral psoriasis in a patient with hepatitis C virus infection.
We report a case of 65-year-old patient with psoriasis vulgaris who developed a psoriatic manifestation on his lower lip, along with typical features of psoriasis on his trunk and extremities. Mucous membranes, palate and tongue were not affected. A biopsy specimen from lip showed acanthosis of the epidermis with parakeratosis, and mild cellular infiltrates in the upper dermis. He was also suffering from type C hepatitis, however, he had not been treated with interferons. Oral psoriasis involving the lip is extremely rare.
