MP/H Rules/Histology--Urinary System: How should histology be coded when there are multiple bladder, ureter and renal pelvis urothelial tumors including non-invasive papillary urothelial carcinoma in the left ureter, invasive papillary urothelial carcinoma invading the lamina propria in the bladder, and an invasive sarcomatoid urothelial carcinoma of the renal pelvis that invades the muscularis? See Discussion.

MP/H Rules/Histology-Urinary: 1) What is the correct ICD-O-3 morphology code for conventional renal cell carcinoma? Is this clear cell carcinoma or does conventional refer to the general diagnosis?

2) If a patient was diagnosed with invasive papillary urothelial carcinoma of the bladder in May 2011 and returns in February 2013 with invasive urothelial carcinoma of the bladder, what is the correct ICD-O-3 morphology code?

MP/H Rules/Histology/Grade--Unknown & ill-defined sites: What is the correct histology and grade of a liver biopsy with metastatic neuroendocrine carcinoma low to intermediate grade if primary site is unknown? See Discussion.

MP/H Rules/Histology/Multiple primaries--GE junction: How is histology coded for a goblet cell carcinoma in the GE junction? See discussion.

MP/H Rules/Histology: How is the histology coded for an invasive adenocarcinoma arising in a papilloma with high-grade dysplasia? See Discussion.

MP/H Rules/Histology: What is the correct histology code for a NUT midline carcinoma?

MP/H Rules/Histology: What is the histology code of serous tubal intraepithelial (in situ) carcinoma (STIC), bilateral fallopian tubes?

MP/H Rules/Histology: What is the proper histology code -- mucin producing adenocarcinoma or cholangiocarcinoma for the following case? See discussion.

MP/H Rules/Kidney, renal pelvis--How many primaries are there for this case? Should we stop at rule M8 making this all one primary (C689) even though there were right and left renal pelvis tumors? Rule M3, which contains laterality, does not apply because there is also a bladder tumor. See discussion.

MP/H Rules/Multiple Primaries--Lung: Does lung MP/H Rule M6 apply to synchronous tumors only, metachronous tumors only, or both? See discussion.
