Chronic conditions such as Recurrent Aphthous Stomatitis (canker sores), Oral Lichen Planus, Pemphigus Vulgaris, and Mucous Membrane Pemphigoid are characterized by recurring erosive or ulcerative patterns. These often require long-term management with corticosteroids or immunomodulators.
The most frequent cause of oral lesions is mechanical, thermal, or chemical trauma (e.g., accidental biting, sharp food, or aspirin burns). These are typically acute and resolve quickly once the irritant is removed. Download Г‰rosions ulcГ©rations muqueuseorale pdf
The primary symptom of these lesions is pain, which often interferes with basic functions such as eating, speaking, and swallowing. Histologically, the loss of epithelial integrity exposes nerve endings in the connective tissue to the oral environment. The inflammatory response that follows leads to the characteristic "fibrinous base"—the yellowish-white coating seen on many ulcers—surrounded by an erythematous (red) halo. These are typically acute and resolve quickly once
Clinical Perspectives on Erosions and Ulcerations of the Oral Mucosa The inflammatory response that follows leads to the
The oral mucosa serves as a vital protective barrier, yet it is frequently the site of various pathological conditions. Among these, erosions and ulcerations are the most common clinical manifestations. While the terms are often used interchangeably, they represent distinct histological processes: an erosion is a superficial loss of the epithelium that does not penetrate the basal layer, whereas an ulceration is a deeper defect that extends into the underlying dermis or lamina propria. Understanding these lesions is critical for clinicians, as they can range from minor localized traumas to early signs of systemic disease or malignancy.
Viral infections, particularly the Herpes Simplex Virus (HSV) and Coxsackievirus (Hand, Foot, and Mouth Disease), often present as multiple painful vesicles that rupture into erosions. Bacterial infections like syphilis or fungal infections in immunocompromised patients also play a role.
A thorough diagnosis begins with a detailed medical history, focusing on the duration, frequency of recurrence, and associated systemic symptoms.
