cords and solid sheets of neoplastic ameloblasts(cells which secrete the enamel proteins) +/- osseous & dentinous elements

31
Q
A

Acanthomatous Ameloblastoma (AA)

could be POF- need histo to determine

32

oral melanoma

40% of tumors in mouth

malignant cat neoplasm

A

oral squamous Cell Carcinoma

41
Q

oral squamous Cell Carcinoma looks

A

large ulcerated masses

extensive surface necrosis & ulceration

highly infiltrative and destroy local tissue and bone

Firm masses from desmoplasia

42
Q

desmoplasia

A

Causing or forming adhesions or fibrous connective tissue within a tumor.

43
