This document provides a 3-step algorithm for diagnosing oral exophytic lesions: 1. Determine the onset and course of the lesion which can indicate inflammatory hyperplasias, benign or malignant tumors, or infections. 2. Examine the location, mobility, and radiographic features of the lesion which can provide clues to whether it is peripheral or central in location and if there are signs of periosteal involvement or tissue invasion. 3. Evaluate the characteristics of the lesion such as its surface, base, and consistency which when combined with location and features can indicate possibilities like inflammatory hyperplasias, benign or malignant tumors, cysts, or infections.

ORAL EXOPHYTIC LESIONS

3. STEP 1
Onset and Course
A) Slow-growing masses: (duration of months to years)
Inflammatory Hyperplasias
Hamartoms
Beningn tumors
Cysts
B) Moderately rapid-growing masses: ( weeks to about 2 months)
Inflammatory Hyperplasias
Chronic infactions
Cysts
Malignant tumors
C) Rapidly growing masses (hours to days)
Abscesses
Infected cysts
Melanoma
Salivary retention phenomena
Hematomas
Burkitt`s lymphoma
