Peripheral Exophytic Oral Lesions: A Clinical Decision Tree

Area of Science:

• Oral Pathology
• Dermatology
• Oncology

Background:

• Peripheral oral exophytic lesions present diagnostic challenges for clinicians.
• Accurate diagnosis is crucial for appropriate patient management and treatment planning.

Purpose of the Study:

• To develop a clinical decision tree for diagnosing peripheral oral exophytic lesions.
• To categorize lesions based on surface texture and origin for simplified diagnosis.

Main Methods:

• A comprehensive literature review was conducted using major databases (PubMed, Scopus, Embase) and textbooks.
• Keywords included "oral soft tissue lesion," "oral exophytic lesion," and "oral mucosal enlargement."
• Articles published between 1988 and 2016 were analyzed.

Main Results:

• Peripheral oral exophytic lesions were classified into smooth-surfaced (mesenchymal/non-squamous origin) and rough-surfaced (squamous origin) categories.
• Smooth lesions were further subgrouped into reactive hyperplastic, salivary gland, and mesenchymal types.
• Rough lesions were summarized into six common types, with 29 entities organized into a stepwise diagnostic tree.

Conclusions:

• The proposed decision tree aids clinicians in systematically diagnosing oral exophytic lesions.
• Categorization by surface texture and origin provides a logical framework for differential diagnosis.
• This tool can improve diagnostic accuracy and streamline the management of oral soft tissue lesions.
