Diseases of the lips

Area of Science:

• Dermatology
• Oral Medicine

Background:

• The lip vermilion represents a unique semi-mucosal transition zone between skin and oral mucosa.
• Understanding lip anatomy is crucial for diagnosing and managing inflammatory conditions.

Purpose of the Study:

• To provide a comprehensive overview of inflammatory diseases of the lips, collectively termed cheilitis.
• To categorize and describe the diverse etiologies and clinical presentations of various cheilitis forms.

Main Methods:

• Literature review and synthesis of existing knowledge on lip inflammatory diseases.
• Classification of cheilitis based on underlying causes and clinical characteristics.

Main Results:

• Cheilitis encompasses a range of conditions including angular, contact, plasma cell, exfoliative, glandular, granulomatous, and actinic types.
• Etiologies vary widely, including infections, irritants, allergens, nutritional deficiencies, autoimmune conditions, and premalignant changes.
• Specific forms like cheilitis glandularis and actinic cheilitis carry premalignant potential.

Conclusions:

• Cheilitis represents a spectrum of inflammatory lip disorders with diverse origins.
• Accurate diagnosis based on clinical presentation and etiology is essential for effective management.
• Recognition of premalignant potential in certain cheilitis forms is critical for early intervention.
