Histology (Pre-2007)/EOD-Lymph Nodes/SEER Summary Stage 2000--Breast: What codes are used to represent these fields for a breast case with a diagnosis of ductal carcinoma in situ and a positive regional lymph node?
Histology (Pre-2007)/Diagnostic Confirmation: Which histology code is preferred if the CBD brushing is positive for malignant cells, cytologically most consistent with ductal adenocarcinoma [8500/3], and the common hepatic artery lymph node biopsy has metastatic adenocarcinoma, consistent with cholangiocarcinoma [8160/3]?
Histology (Pre-2007)/Diagnostic Confirmation: What code is used to represent the histology that initially presents on uterine curettage as a hydatidiform mole and after pulmonary metastases develop a month later, the clinical diagnosis is "metastatic gestational trophoblastic disease"?
Histology (Pre-2007)/CS Tumor Size/CS Extension--Colon: How are these fields coded if a 3 cm sessile polyp is snared and removed piecemeal during a colonoscopy and the path microscopic description indicates a polypoid lesion with foci of malignant transformation found associated with bundles of smooth muscles followed by a LAR with no residual invasive tumor but the final path diagnosis is stated to be a M.D. adenocarcinoma? See Discussion.
Histology (Pre-2007)/Behavior Code: What code is used to represent the histology "foci of well differentiated intramucosal carcinoma [carcinoma in situ] arising on the surface of a tubular adenoma"? The pathologist referred to this colon biopsy as "in situ".
Histology (Pre-2007)/Behavior Code/Sequence Number-Central -- Ovary: How are these fields coded for a "serous tumor of low malignant potential" when lymph nodes are discovered to be involved?
Histology (Pre-2007)--Testis: What code is used to represent the histology of "mixed germ cell tumor, embryonal carcinoma and mature teratoma" of the testis? See discussion.
Histology (Pre-2007)--Stomach: What code is used to represent the histology of "mucin-secreting adenocarcinoma, intestinal type "for a stomach primary?
