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.
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.
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"?
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?
EOD-Size of Primary Tumor: The EOD Manual instructs us not to code the size of a cyst. Can we code the size of tumor lesions described as being multicystic, multiloculated, or as a complex mass with cystic areas? See discussion.
Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)?
Multiple Primaries (Pre-2007)--Breast: When simultaneously diagnosed breast tumors of the same histology in the same breast are stated by the pathologist and/or clinician to be more than one primary, should these be reported as multiple primaries? See discussion.
