Chronic Ulcerative Stomatitis (CUS) is a rare, chronic inflammatory disorder that affects the lining of the mouth. It is characterized by persistent or recurring painful ulcers that can interfere with eating, speaking, and maintaining good oral hygiene. Although the exact cause is not fully understood, CUS is believed to result from an abnormal autoimmune response in which the body's immune system attacks the oral mucosa. Genetic factors, stress, hormonal changes, and certain medications may also contribute to its development.

Understanding the underlying immune dysfunction is important for early diagnosis, effective treatment, and long-term symptom management.

What are the Types of Chronic Ulcerative Stomatitis?

Chronic Ulcerative Stomatitis may present in different clinical forms based on the appearance and severity of oral ulcers.

Major Aphthous Ulcerations: Large, painful ulcers that commonly affect the gums, tongue, and inner cheeks.
Minor Aphthous Ulcerations: Small, round ulcers that usually develop on the inside of the lips and cheeks.
Herpetiform Ulcerations: Multiple tiny ulcers that cluster together and resemble herpes-related sores.
Ulcerative Lichen Planus: Characterized by white, lace-like patches accompanied by painful oral ulcers.
Erosive Lichen Planus: Causes erosion of the oral lining, resulting in painful ulcers and persistent discomfort.
