20021156 Primary Site/Histology (Pre-2007): What codes are used to represent site and histology for BSO specimen with a diagnosis, "Left and right adnexa: poorly differentiated serous carcinoma.

Primary Site: What code is used to represent the primary site for a "teratocarcinoma with features of embryonal carcinoma" removed from the thigh muscle in a patient with x-ray negative testicles? See discussion.
20021153 Grade, Differentiation--Breast: Is "histological grade" another way of saying "tubule formation" which would result in the following case having a Bloom-Richardson (BR) score of 7 which would be coded to grade 2? See discussion.

Reportability: A "gastrointestinal stromal tumor" (GIST) is not always stated to be "malignant" in the path report even though the tumor appears to meet criteria for malignancy. Is the tumor SEER reportable? See discussion.

20021149 EOD-Extension--Head & Neck: In the absence of a clear surgical or pathologic description of how the salivary gland involvement relates to the head and neck primary, do we code the involvement as direct extension, further extension or metastasis? See discussion.

Other Cancer Directed Therapy--Hematopoietic, NOS: Is "aspirin" treatment for primary polycythemia? See discussion.
20021146 Primary Site--Lymphoma: Is the primary site likely to be extranodal for a lymphoma that presents in an extranodal site and lymph nodes which are regional for that site? Is the primary site also likely to be extranodal if an extranodal site and lymph nodes are excised? See discussion.
20021144 EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)?
