 Morphology: grossly: cauliflower-like, polyp,
mushroom-like, ulceration.
 口腔鳞癌早期多表现为非均质性白斑、红斑，
浅的糜烂和溃疡。
2. Basal cell carcinoma
Origin: basal cells of skin
Features: locally invasive growth, almost
never metastasis commonly in face of
ololster.
3. Transitional cell carcinoma
 Origin: transitional cells of the urinary
bladder or renal pelvis.
Features: exoteric, finger-like, commonly in
bladder, renal pelvis.
