1

Cancer def

– General term frequently used to indicate any of
various types of malignant neoplasms, most of
which invade surrounding tissues, may
metastasize to several sites, and are likely to recur
after attempted removal and to cause death to
the patient unless adequately treated

2

Tumor def

swelling

3

Harmatoma

disorganized overgrowth of normal tissue in its normal location

4

choristoma def

growth of normal tissue in an abnormal location

5

Neoplasm Def

Growth of abnormal tissue, may be either benign or malignant

6

Adenoma

usually a benign neoplasm: Pleomorphic
adenoma, oncocytoma

7

Carcinoma

– Malignant neoplasm derived from epithelial cells
• Surface (skin, mucosal): Basal cell carcinoma
• Glandular: Adenocarcinoma

8

Sarcoma

Malignant neoplasm rom mesoderm

9

Erythroplakia

• Red patch or plaque-like lesion that cannot be
clinically or pathologically diagnosed as any
other condition
• Often represents malignant change
– Up to 90% of erythroplakic lesions represent
severe epithelial dysplasia, carcinoma in situ, or
SCCa

10

Erythroleukoplakia

– Frequently dysplasia or carcinoma in situ on
biopsy

11

Proliferative Verrucous Leukoplakia

• High-risk form of leukoplakia
• Multiple keratotic plaques
– Roughened surface projections
• Persistent growth
– Exophytic, verrucous
• m:f 1:4 (female predilection)
• Minimal association with tobacco use
• Characterized by multiple, persistent, keratotic
plaques that over time progress to SCC
– Verrucous hyperplasia ®verrucous carcinoma ®
invasive squamous cell carcinoma
– Lesions rarely regress despite therapy
