what does a cd117 stain on a bladder biopsy show exactly?

Mast cells: Among other things, this lights up mast cells, which tend to be increased in interstitial cystitis which may be a diagnostic consideration. Leave interpretation up to the pathologist; if there's a question, ask for a few other pathologists to look at the biopsy.
