Report Question ID Question
20021078 Primary Site: How do you code the primary site when the tumor is identified in a bladder that was reconstructed using a stomach augmentation procedure and the pathology report states, "Bladder/prostate: adenocarcinoma arising within gastric mucosa, with the following features: highly infiltrative through the bladder wall"?
20021077 Histology (Pre-2007)/Primary Site/EOD-Extension--All Sites: How do you code these fields for a resected thyroid that is negative for any diagnostic abnormality and a left ovary that demonstrates "papillary thyroid carcinoma arising in a cystic teratoma"? See discussion.
20021074 Tumor Markers--Breast: If the ERA/PRA results reported differ for separate breast specimens removed for a single primary, do we code the results as positive or negative?
20021072 EOD-Size of Primary Tumor--Breast: The path report provides a size for both the Paget disease and the underlying intraductal component in the breast. Should we assume the Paget disease to be invasive and code the size of the primary tumor to that invasive component? See discussion.
20021070 CS Extension/CS Lymph Nodes--Breast: How would you interpret the phrase "axillary lymph node tissue, not clearly a lymph node" or the phrase "satellite nodule of invasive tumor, left axillary lymph node or chest wall tissue"? See discussion.
20021069 Histology (Pre-2007)--Breast: What code is used to represent the histology "infiltrating lobular carcinoma, solid and classical subtypes"?
20021066 Histology: How do we code this field when a less representative specimen has a more specific morphology? See discussion.
20021063 EOD-Pathologic Review of Number of Regional Lymph Nodes Examined: What code is used to represent this field when a path report from a lymph node biopsy or dissection describes lymph node "portions" or "fragments"? See discussion.
20021062 Histology (Pre-2007)--Breast: What code is used to represent histology for "invasive ductal carcinoma with squamous differentiation"? Is "squamous differentiation" synonymous with "squamous metaplasia"?
20021061 Multiple Primaries/Histology--Mycosis Fungoides/Cutaneous T cell Lymphoma: Physicians often use the terms cutaneous T cell lymphoma (CTCL) and mycosis fungoides interchangeably and yet the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that these 2 diagnoses represent separate primaries. Do these cases represent one primary? If so, what histologic type should they be coded to?
