Rapid
Profitable to practice
What is the nuclear criteria for malignancy?
Anisokaryosis Abnormally clumped Chromatin Abnormal nuclei Micronuclei Variable sized nuclei in same cell Nuclear molding
What are the three classifications of tumors?

Round and Individual
What is the suffix for a benign tumors of epithelial origin?
-oma
What is the suffix for a malignant tumor of epithelial origin?
carcinoma
What is the suffix for a benign tumor of a gland?
-Adenoma
What is the suffix for a malignant tumor of a gland?

What are some characteristics of Epithelial tumors?
Cells in sheets or clusters many cell present distinct cytoplasmic borders cells often large with abundant cytoplasm shows signs of differentiation
What are the characteristics of Mesenchymal tumors?
Elongated nuclei and cytoplasmic tails (spindle cells)
Few cells present
cells are individual but in clusters sometimes with intracellular matrix
Active fibroblasts resemble malignant mesenchymal cells
