Overview
Based on the growth pattern, transitional cell carcinoma may be classified into either papillary urothelial carcinoma or non-papillary urothelial carcinoma. Transitional cell carcinoma may be classified according to World Health Organization in a collaborative effort conjointly with the International Society of Urological Pathologists (ISUP) into two groups: infiltrating urothelial carcinomas and non-invasive urothelial carcinomas.Based on the degree of cellular differentiation, transitional cell carcinoma may be classified into two grades: low grade and high grade.
Classification
Based on the growth pattern, transitional cell carcinoma may be classified into two subtypes:[1]
| Type | Description |
|---|---|
|
Papillary urothelial carcinoma |
|
|
Non-papillary urothelial carcinoma |
|
WHO Classification
Transitional cell carcinomas may be classified according to World Health Organization in a collaborative effort conjointly with the International Society of Urological Pathologists (ISUP) into two groups: infiltrating urothelial carcinomas and non-invasive urothelial carcinomas:[2]
| Transitional cell tumors | |||||||||||||||
Infiltrating urothelial carcinoma

Non-invasive urothelial carcinoma

Grading
According to the WHO grading criteria, there are two grades of transitional cell carcinoma based on the degree of cellular differentiation:
| Grade | Description |
|---|---|
|
Low grade |
|
|
High grade |
