Question:
Reportability/Histology--Bladder: Is papillary urothelial neoplasm of low malignant potential (PUNLMP) (8130/1) reportable when also referred to as papillary transitional cell carcinoma, grade 1, no invasion (8130/2) previously? See Discussion.
Discussion:
The pathology report reads: Urinary bladder, tumor over right ureteral orifice, biopsy: Urinary bladder mucosa (urothelium) and submucosa (lamina propria), with papillary urothelial neoplasm of low malignant potential (previously known as papillary transitional cell carcinoma, grade 1 of 3), no invasion identified.
Answer:
This case is not reportable. PUNLMP (8130/1) is the diagnosis stated by the pathologist for this case and PUNLMP is not reportable. The information in parentheses is informational in this case and does not change the pathologist's diagnosis.
According to WHO Classification of Tumors of the Urinary System and Male Genital Organs, 4th edition, there is variation of architectural and cytological features between PUNLMP and papillary urothelial carcinoma, low grade, reflecting grading changes from an older classification system.
