Code histology to 9732/3 [multiple myeloma]. The plasmablastic subtype/variant does have a prognostic indication, but the disease is still coded as multiple myeloma.

Grade--Heme & Lymphoid Neoplasms: Is the phrase "aberrant T-cell expression" enough to code the grade field to T-cell when the final diagnosis on the pathology report is "AML with aberrant T-cell antigen expression"?
Yes. Code grade to 5 [T-cell]. The T cell receptor, or TCR, is a molecule found on the surface of T lymphocytes (or T cells).
Surgery of Primary Site--Brain and CNS: Is "debulking" of a primary brain tumor coded to 21 [subtotal resection of tumor] or 30 [gross resection of tumor]?
Assign code 21 [subtotal resection of tumor, lesion, or mass]. Debulking removes as much of the tumor volume as possible in cases where it is not possible to remove the entire tumor. Debulking should improve the effectiveness of subsequent radiation therapy and/or chemotherapy.
MP/H Rules/Histology--Brain and CNS: How is histology coded for a left occipital parietal area tumor stated to be a "low grade neuroectodermal neoplasm most consistent with neuronal tumor but lacking classic features of ganglioma" if the pathologist states the tumor is not malignant?
Code 9505/0 [Ganglioglioma, benign] is the best option according to our pathology expert. He states, "There recently has been a spate of tumors called low grade glio-neuronal tumors that are not PNETs and have no propensity to become malignant."
Primary site--Heme & Lymphoid Neoplasms: Is C448 [overlapping lesion of skin] or C449 [skin, NOS] the appropriate site code for a 2008 diagnosis of mycosis fungoides involving over 40 percent of the skin surface, including both upper and lower extremities and trunk?
Code the primary site to C449 [skin, NOS]. The code C448 should be used when there is a single overlapping lesion that includes all the disease. The patient has extensive skin coverage involving multiple skin subsites (upper and lower extremities and the trunk), but it is unlikely there is ONE plaque (one lesion) overlapping all these different skin subsites. The disease has more likely presented as multiple plaques (lesions) in these different areas.
MP/H Rules/Histology--Melanoma: Regarding SINQ #20081044, when would you apply Rule H6 rather than Rule H5 for a cutaneous malignant melanoma given that you normally always have a specific cell type mentioned?
For cases diagnosed 2007 or later, Rule H6 is used when you do not have a specific cell type other than regressing melanoma, or malignant melanoma, regressing. If you have regressing melanoma with a specific cell type, apply rule H5.
Ambiguous terminology/Reportability--Heme & Lymphoid Neoplasms: Should a case be accessioned as MDS, NOS when a consult uses ambiguous terminology (e.g., probable MDS) to describe the disease process and the bone marrow does not confirm the consult diagnosis? See Discussion.
A patient is stated to have "probable MDS" by a hematology oncologist consult during an admission. A bone marrow biopsy was also performed during this admission, the final diagnosis on the pathology report is, "anemia and thrombocytopenia." The patient was not seen again by a hematology oncologist; however the patient's cardiology states, "BM biopsy was not clear whether this is MDS or another etiology."
This is not reportable. In effect, the original diagnosis was a rule/out MDS diagnosis. The bone marrow biopsy performed as part of the initial workup, proved that rule/out diagnosis was not valid. The subsequent statement confirms the diagnosis is not clear.

MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if a pathology specimen reveals an infiltrating mammary carcinoma with mixed tubular and lobular features, 2.3 cm, low grade cribriform in situ ductal carcinoma, and Paget disease of the overlying skin with ulceration? See Discussion.
According to SINQ 20081134 the histology would be 8524 if this is one primary.
For cases diagnosed 2007 or later, this is a single primary.
In order to determine whether this case represents a single or multiple primary, you must first determine the correct histology code for the underlying tumor. Using rule H9, ignore the DCIS.
See Table 3 in the equivalent terms and definitions. Infiltrating lobular, tubular, and Paget are coded to a single histology code (8524/3). Our current multiple primary rules do not say infiltrating lobular and tubular and Paget are a single primary. This was an omission and will be corrected in a future revision. Thank you for bringing this omission to our attention.
Primary site--Heme & Lymphoid Neoplasms: How is this field coded when a 5/26/10 colonoscopy reveals ulcers in the cecum, ascending, transverse, descending, and sigmoid colon and, the final diagnosis on the pathology report is post-transplant lymphoproliferative disorder [9971/3]?
Code the primary site to C189 [Colon, NOS] per Rule PH1.
Code the primary site to C189 [Colon, NOS] and not C188 [Colon, overlapping lesion] because there are multiple ulcers in different segments of the colon. The .8 code is used only for a single lesion that overlaps subsites.

No. This is not a reportable hematologic condition. When you do not find a hematologic or lymphoid condition listed in the Heme DB, it is not reportable. Hemophagocytic lymphohistiocytosis is an uncommon hematologic disorder. The patient usually presents with fever, splenomegaly, and jaundice. Laboratory findings are lymphocytosis and histiocytosis. Pathology findings are hemophagocytosis.
Appendix F lists this term as non-reportable.
