Oral Psoriasis of the Tongue: A Case Report.

Psoriasis is a common dermatological disease, but oral psoriasis is rarely reported in the literature. Its diagnosis has been a contentious issue among physicians. Its presence in the absence of skin lesions is not completely accepted by all physicians, and diagnosis is complicated by the fact that there are no defined criteria. We present a case report of oral psoriasis in a man who did not have skin lesions concurrently but did have a previous history of dermal psoriasis. Additionally, we discuss the history, typical presentation, and current treatments of oral psoriasis.
