Direct result of pathologic traumatic or physical infliction on tissue
Primary lesion
Flat circumscribed alteration of tissue
Macule
Another type of macule but larger in size
Patch
A flat surface and raised edges

Similar to papule but larger in size
Nodule
Single or group of elevation and less than 1 cm
Vesicle
Larger size of vesicle
Bulla
Vesicle that contains pus
Pustule
Increase in tissue size due to increase of number of cells
Hyperplasia
Increase in size of skelatal muscle
Hypertrophy
Due to progressive, degenerative or reparative changes
Secondary lesion
Gradual loss of tissue substances and in superficial only
Erosion
Loss of surface tissue due to necrotic inflammation tissue extending to lamina propia

List of possible diseases
Differential diagnosis
Common to cheek chewer

White pigmented,vesicular-ulcerated erythematous
Surface lesions
Swell, reactive, tumor or neoplasm
Soft tissue enlargement
Most common oral soft tissue lesions
Ulcers
Caused by immune dysfunction and covered by white-yellow pseudomembrane and surrounded by erythematous halo
Apthous stomatitis
located in the fingers
Herpetic whitlow
Located in perioral skin
Herpetic labialis
