EOD-Extension--Thyroid: Is this field coded as involvement of the thyroid capsule if the thyroidectomy path specimen reveals papillary thyroid ca "tumor present within capsular blood vessels?"

EOD-Extension--Pancreas: Should these terms be ignored when coding extension to 10 or 30, or do they indicate involvement for non-surgically treated pancreas primaries?

2) Common bile duct is narrowed

3) Common bile duct is obstructed

4) Common bile duct dilation

5) Malignant stricture of the common bile duct

EOD-Extension--Lymphoma: Would a lymphoma involving mesenteric and retroperitoneal nodes (both site code C77.2) be coded to extension 10 [Involvement of a single lymph node region; Stage I], based on the fact that while more than one "chain" is involved only one "region" is involved?

EOD-Extension--Lymphoma: Should "bilateral" inguinal lymph node involvement by lymphoma be two chains for the purpose of coding EOD?

EOD-Extension--Lymphoma: How do you code stage and EOD for an extranodal lymphoma with bilateral involvement of a paired site? See discussion.

EOD-Extension--Lung: If a CT scan indicates that a patient has evidence of "long-standing pneumonia," is that synonymous with "pneumonitis" for the purposes of coding extension for lung primaries?

EOD-Extension--Kaposi Sarcoma: Is a "markedly enlarged spleen" involvement for cases of Kaposi Sarcoma?

EOD-Extension--Head & Neck (Larynx): When "fixed" is stated for a larynx primary does it specifically have to say that it is the vocal cord that is fixed? Are the terms "fixed" and "immobile" synonymous? Should these cases be coded to 40 rather than 35? See discussion.

EOD-Extension--Colon: Is a pathology description of "superficial invasion of the muscularis mucosa in the upper stalk of the polyp" coded in this field to 10 [mucosa (including intramucosal) NOS], 12 [Muscularis mucosa], or 14 [Stalk of polyp]? See Description.
