Tumor Size--Pathologic--Anus: In 2019, the pathology report of an anal canal squamous cell carcinoma stated the tumor size is 2.5 cm from proximal to distal (3.5 cm in circumference). Is the pathologic tumor size tumor size 025 or 035?
Primary Site/In Situ: How is primary site coded for an in situ carcinoma arising in a mucinous cystadenoma with ovarian stroma (focal) located in the right lobe of the liver? See discussion.
Reportability--Heme & Lymphoid Neoplasms: Is this a reportable case and if so what codes would be used for the primary site and histology?
Lymph node flow cytometry and bone marrow biopsy revealed involvement by a low-grade B-cell lymphoproliferative disorder. Medical oncologist states monoclonal gammopathy, question marginal zone B cell lymphoma versus lymphoplasmacytic lymphoma/lymphoproliferative disorder.
Reportability--Ovary: Is an adult granulosa cell tumor of the right adnexa reportable if the left adnexa, diaphragm and paratubal tissue are reported to be consistent with metastasis? See discussion.
MP/H Rules/Multiple primaries--Brain and CNS: How many primaries should be abstracted for a patient with a 2011 diagnosis of oligodendroglioma followed by biopsy of tumor which demonstrated progression in 2016 with pathology report Final Diagnosis indicating WHO grade III anaplastic astrocytoma? See Discussion.
Solid Tumor Rules (2018)/Histology--Breast: How is the histology coded and which H Rule applies for a single tumor with final diagnosis of invasive mammary carcinoma and College of American Pathologists (CAP) synoptic report states, Histologic type: Invasive cribriform carcinoma with no mention of a tumor percentage? See Discussion.
Update to current manual/SS2018--Breast: Should Code 3 of the Summary Stage 2018 (SS2018) for Breast designate the intramammary and infraclavicular lymph nodes as being ipsilateral? Similarly, should Code 7 designate infraclavicular lymph nodes as contralateral/bilateral? Laterality (ipsilateral, contralateral/bilateral) is included for axillary and internal mammary nodes in the respective codes.
Primary Site/EOD-Size of Primary Tumor--Lung: If the only lung mass described in CXR is a "hilar mass," is the primary site coded to C34.9 [Lung, NOS] or C34.0 [Main Bronchus; incl. Carina]? Also, can the size of the hilar mass be used to code the size of tumor field?
Primary site/Reportability--Breast: Is a "right nipple skin" biopsy that demonstrates squamous cell carcinoma reportable using a primary site of C500? See Discussion.
