Reportability: Is a tumor reported as "neoplasm" or "neoplasia" per the pathology report, which is subsequently clinically referred to as "carcinoma" reportable? See Discussion.
Solid Tumor Rules (2018/2021)/Multiple Primaries--Brain and CNS: How many primaries should be accessioned and what multiple primaries/histology rules apply to a meningioma of the spinal meninges and a meningioma of the cerebral meninges? See Discussion.
Reportability--Heme & Lymphoid Neoplasms: Is a diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) with large cell transformation equivalent to a diagnosis of diffuse large B-cell lymphoma (DLBCL) without mention of Richter transformation or Richter Syndrome? See Discussion.
MP/H Rules/Recurrence--Ovary: How many primaries are accessioned if a patient was diagnosed with ovarian serous carcinoma four years ago and currently has sacral and pelvic masses positive for serous carcinoma on biopsy? Should this be disease progression or a new primary? See Discussion.
MP/H Rules/Multiple primaries--Lung: How many primaries are accessioned and which M rule applies for a 2010 diagnosis of clear cell adenocarcinoma of the left upper lobe lung followed by a 2012 diagnosis of adenosquamous carcinoma of lung origin without evidence of a primary lung tumor? See Discussion.
Solid Tumor Rules (2018)--Breast: How many primaries are accessioned when a prophylactic mastectomy reveals a final diagnosis of invasive tubular carcinoma, but the College of American Pathologists (CAP) Protocol includes ductal carcinoma in situ (DCIS) sized separately and it is not clear if these are different tumors? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when an excisional biopsy of a chest wall nodule shows diffuse large B-cell lymphoma (40%) and follicular lymphoma, grade 3A (60%)? See Discussion.
Solid Tumor Rules (2018)/Multiple Primaries--Head & Neck: How many primaries are accessioned and what M Rule applies when a patient is diagnosed with a right lateral tongue (C023) tumor in 2016 that was verrucous carcinoma (8051), followed by a new left tongue border (C021) tumor in 2019 that was squamous cell carcinoma, NOS (8070)? See Discussion.
Ambiguous Terminology/Date of Diagnosis: How would you code the diagnosis date when the body of an imaging report uses reportable ambiguous terminology while the final impression in that same report uses non-reportable ambiguous terminology? Would you code the diagnosis date to the date of the scan or to the subsequent biopsy date that confirmed a malignancy? See Discussion.
Solid Tumor Rules/Multiple Primaries--Lung: How many cases should be abstracted for a patient with 2022 wedge biopsy of right upper lobe acinar predominant lung adenocarcinoma and wedge biopsy of right lower lobe lepidic predominant adenocarcinoma if there is concern for diffuse spread throughout the lungs secondary to the lymphangitic carcinomatosis and possible diffuse pneumonic type of adenocarcinoma? See Discussion.
