Soft Tissue Presentation Flashcards
Define Incisional biopsy
Removal of only a part of the lesion
Define Excisional Biopsy
Removal of the entire lesion
Define Surgical Excision
Removal of the entire lesion +/- border of non-lesional tissue
What does a surgical excision not specify?
If only the lesion itself is removed or the lesion and a border of normal/non-lesional tissue is removed
What is typically removed with malignant lesions or locally invasive lesions?
Border of non-lesional tissue
Define marginal excision
A margin of non-lesional tissue
Define wide excision

Benign Reactive Lesions AKA _____ ____
Non-neoplastic
Define Benign Reactive Lesions
A lesion that occurs from local trauma or other irritant
What are the types of benign reactive lesions?
Fibroma 3 P's Verruciform xanthoma Epulis Fissuratum Inflammatory Papillary hyperplasia Amalgam Tattoo
What are the 3 P’s?
Pyogenic Granuloma
Peripheral Ossifying FIbroma
Peripheral Giant Cell Granuloma
Fibroma: Etiology
Reactive hyperplasia of fibrous connective tissue as a result of chronic irritation
Fibroma: Clinical Features
- Asymptomatic, soft, tan/pink, smooth-surfaced nodule

Why do we lump the 3 P’s together?
Each lesion has some unique features however we usually consider all of these on our DDX for a “bump on the gingiva” as they share many of the same clinical characteristics
