Here are two images of benign urothelial cells.

First a 'tidy' set of layers forming the urothelium.

Urothelium normally consists of 4 to 6 layers of cells. The uppermost layer consists of umbrella cells (not well seen in this image) which may have irregular hyperchromatic nuclei.

Second a more disparate set.

The urothelial cells are somewhat disorganized in this example, however, they are still clearly benign. The lamina propria (the pale area) is edematous (swollen with fluid); probably a symptom of the scattered inflammatory cells (pink).

The next image is one from the urinary cytology test I had in June 2008

The report on this is: A papillary group of cells, which I would regard as highly suspicious of well-differentiated papillary transitional cell carcinoma' Dr N J Robertson. Derriford Hospital, Plymouth.
