Primary site--Bladder: What is the primary site for bladder tumor biopsy: invasive adenocarcinoma, enteric type favor urachal origin, stage III
Based on the information provided, code the primary site to urachus (C677). Primary adenocarcinoma of the bladder accounts for less than 1% of all bladder malignancies. Of these, 20–39% are urachal in origin.
MP/H Rules/Histology--Bladder: What is the correct histology for the following bladder case and how do you determine? See discussion.
8/1/10 CYSTOSCOPY -- MULTIPLE BLADDER TUMORS INVOLVING POSTERIOR WALL, DOME & BLADDER NECK AREA. LARGEST WOULD BE MORE THAN 5 CM IN SIZE. 8/17/10 path -- BLADDER TUMORS:PAPILLARY TRANSITIONAL CELL CARCINOMA OF urinary bladder, GRADE III. ONE FRAGMENT OF TISSUE SHOWS NECROTIC CHANGE WITH APPARENT TRANSFORMATION TO A HIGH GRADE SARCOMATOID VARIANT W ITH EXTENSIVE SUBMUCOSAL INVASION & FOCAL AREA SUGGESTIVE OF ANGIOLYMPHATIC INVASION NOTED. MAJORITY OF TUMOR APPEARS CONFINED TO MUCOSAL SURFACE W ITH NO OTHER AREAS OF DEFINITIVE SUBMUCOSAL INVASION FOUND.
Code 8122/3 (UC/TCC, Sarcomatoid). Rule H5 and Table 1 apply.
This is based on the information provided: Transitional Cell Carcinoma with sarcomatoid variant, and Table 1 in Terms and Definitions for "Ureter/Renal Pelvis/Bladder".
Multiple primaries--Heme & Lymphoid Neoplasms: Should the 2014 diagnosis be abstracted as a new primary since it is not mantle cell lymphoma and all of the types listed in the differential diagnosis would be a new primary? See discussion.
Mantle cell lymphoma diagnosed in 1997 which was treated with chemotherapy. Now in 2014 a 'relapse' of non-Hodgkin lymphoma. They do a biopsy of the pericardium, which is called low grade B cell non Hodgkin lymphoma. See comment. The comment says histochemical stains are reviewed and findings are consistent with involvement by a CD5 positive low grade B cell lymphoma. Lack of cyclin D1 and SOX-11 positivity as well as negative IGH-CCND1 FISH analysis essentially rule out mantle cell lymphoma. The morphologic and immunophenotypic features of this disorder are not specific for any lymphoma subtype. The differential includes CLL, marginal zone lymphoma, and lymphoplasmacytic lymphoma. If this is coded NHL, NOS (9591) it is the same primary as seq. 1 and would not be abstracted.
This is the same primary, the mantle cell lymphoma.
Differential diagnoses cannot be used to assign histology. For the 2014 diagnosis, the only histology that can be assigned is 9591/3 for non-Hodgkin lymphoma, NOS. (CLL, mantle cell lymphoma and lymphoplasmacytic lymphoma are all NHL's.)
Compare the 1997 diganosis of mantle cell lymphoma with the 2014 diagnosis of non-Hodgkin lymphoma. Start with Rule M1. The first rule that applies is Rule M15, which instructs you to use the multiple primaries calculator. Enter 9673/3 and then 9591/3 and then calculate. The result is same primary.
If at a later time one of the differential diagnoses is confirmed, apply the rules again.
MP/H Rules/Multiple primaries--Ampulla of vater: Is this a new primary? Patient has intramucosal adenocarcinoma in a tubulovillous adenoma of the ampula of vater in Sept. of 2011. In May of 2012, patient has another ampullary adenoma with intraepithelial carcinoma (pTis) and an area suspicious for invasion. This is coded 8263/3.
Rule M14, Multiple in situ and/or malignant polyps are a single primary, precedes rule M15, An invasive tumor following an in situ tumor more than 60 days after diagnosis is a multiple primary, per the MP rules for 'Other sites',
Rule M14 applies. Abstract this case as a single primary.
Surgery of Primary Site--Lung: How is surgery coded when a patient undergoes a mediastinoscopy with mediastinal lymph node sampling and then a later upper lobectomy? See discussion.
The mediastinal nodes were submitted as a separate specimen. The patient also had several peribronchial nodes identified within the lobectomy specimen.
Does code 33 (Lobectomy with mediastinal lymph node dissection) require a complete mediastinal lymph node dissection (i.e. the removal of all lymph nodes in mediastinal chain(s) as opposed to a selective sampling/dissection of lymph nodes from multiple mediastinal chains)?
Assign code 33 in this situation. Code 33 can include mediastinal lymph node sampling.
Multiple primaries--Heme & Lymphoid Neoplasms: Is this abstracted as one primary or two?
5/2/13 Bone Marrow biopsy: myelodysplastic syndrome with approaching to acute myeloid leukemia with del 5q and 7q deletions. FISH: deletion of chromosome 5q and deletion of chromosome 7q detected.
I checked the Heme DB manual and there is no term "With approaching to". I checked the Multiple Primary calculator and it says new primary. My interpretation is that the myelodysplastic syndrome is in the process of transforming to acute myeloid leukemia.
Abstract a single primary, myelodysplastic syndrome with del 5q and 7q deletions (9986/3). This neoplasm can transform to acute myeloid leukemia (AML); however, "with approaching to" cannot be used to report this AML.
MP/H/Histology--Kidney, renal pelvis: What is the histology code for renal cell carcinoma translocation type?
Code renal cell carcinoma translocation type as renal cell carcinoma, NOS, 8312. While WHO recognizes renal cell carcinomas with associated translocations, there is no specific ICD-O-3 code for this variant of renal cell carcinoma.
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?
Code as a single primary with histology Diffuse Large B-Cell Lymphoma.
In this case, there are two NHLs in the same location at the same time. Apply Rule M4, this is one primary. Per Note 5 under Rule M4, go to Rules PH11and PH15 to assign primary site and histology.
Rule PH11 states to code to the site of the origin (axillary mass) and to diffuse large b-cell lymphoma (9680/3) when DLBCL and any other non-Hodgkin lymphoma (follicular in this case) are present in the same location at the same time.
Using the multiple primaries calculator in this situation will give you two primaries, which is the wrong answer. Use the rules before using the calculator.
To get to the manual, go to the "Help me code for dx year." section. Choose 2010 or later and the most current manual will appear. We recommend that you save a copy of the PDF on your computer.
MP/H Rules/Histology--Lung: What is the correct histology code for this lung tumor? FINAL PATHOLOGIC DIAGNOSIS: CT-guided Rotex and Franseen needle biopsies: Positive for malignancy, consistent with adenocarcinoma. Comment: the adenocarcinoma present also shows rare CD56 staining which indicates a neuroendocrine component.
Is this a mixed histology? 8045/3? 8244/3?
Assign histology code 8140/3, adenocarcinoma, based on the final diagnosis. The neuroendocrine component in this case is not another histology, nor is it a more specific adenocarcinoma. "Component" is not one of the words that we use to indicate a more specific histology.
