6How to Diagnose Oral Psoriasis
Since the symptoms of oral psoriasis resemble those of other disorders, it can be challenging to diagnose the condition. In fact, some doctors do not think that oral psoriasis is a form of psoriasis. There are currently no clinical criteria to help diagnose this disease. Your doctor may perform a physical exam to look for possible signs. A diagnosis can be made by ruling out other disorders that would cause similar symptoms. To confirm the diagnosis, a skin biopsy may be taken and further analysed in the lab. [6]
