Inquiry Details
References:
WHO Class Endocrine Tumors. 4th ed.
Question:
Histology--Thyroid: Should any mention of encapsulated be included in the histology coding (8343/3 vs. 8260/3) for papillary thyroid carcinoma cases? See Discussion.
Discussion:
Example: Left thyroid lobectomy with final diagnosis
When the only mention of encapsulation is included in the tumor characteristics of the College of American Pathologists (CAP) summary, not the pathologist's choice of histologic type, what is the preferred histology?
Answer:
Assign 8343/3 for encapsulated variant of papillary thyroid carcinoma. If the pathology report is not available, use the histologic type in addition to other information in the CAP Protocol.
