A Case of Psoriasis with a Chronic Oral Ulcer / 대한피부과학회지

ABSTRACT

Psoriasis is a chronic inflammatory disease with epidermal hyperplasia. Th 1 cells are thought to be important in the pathogenesis of psoriasis and Behcet's disease. However, both diseases rarely develop in the same patient. We report here a case of a 50-year-old man who was diagnosed with psoriasis 15 years prior. During the last three years, ulcers and erosions had recurrently developed on the perianal area and oral mucosa. In addition, the patient had mild arthralgia on the both knees and hand for two years. In this case, Behcet's disease accompanying psoriasis was suspected.
