Grade--Heme & Lymphoid Neoplasms: Why isn't "T-cell granular lymphocytic leukemia" (9831/3) coded as "5 T-cell" instead of "9" as specified in the Heme database? My path department did not specify any type of grade, but since "T-cell" is part of the name, wouldn't you code it to "5"?
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.
Final Dx for left Breast biopsy: Atypical epithelial proliferation (ADH/DCIS). Comment: Sections show small focus of atypical epithelial proliferation with features of atypical duct hyperplasia/low grade duct carcinoma in-situ.
Multiple Primaries--Heme & Lymphoid Neoplasms: 2012 path report for removal of an "axillary mass" which consists of 80% diffuse large B-cell lymphoma (DLBCL) and 20% follicular lymphoma. In the original manual, Module 6 instructed us to code as a single primary, DLBCL. However, the multiple primary calculator says each disease is a separate primary. When I looked them up in the data base, I did not get an option to review a current manual. Can you please advise?
Primary site--Heme & Lymphoid Neoplasms: Is there an instruction missing under Rule PH22 of the 2014 Heme Manual that addresses when it might be appropriate to code primary site to C779 for a Stage II lymphoma? See discussion.
First course treatment/Surgery of Primary Site--Anus: Would infrared coagulation be coded as treatment for AIN III of the anus/anal canal? See discussion.
Primary site--Brain and CNS: How should primary site be coded for a medulloblastoma described as a "posterior fossa mass" and "centered within the fourth ventricle"? See discussion.
