MP/H Rules/Histology--Head & Neck: Please clarify rule H3. The first statement is "Do not code terms that do not appear in the histology description". The second statement is "Do not code...unless the words...appear in the final diagnosis"

One of our pathology labs frequently will state "keratinizing squamous cell" in the microscopic description (histologic description), but only state "squamous cell carcinoma" in the final diagnosis. May we code from the histologic description if it's not in the final diagnosis?

MP/H Rules/Histology--Thyroid: When is 8341/3, papillary microcarcinoma coded? The code description in ICD-O-3 is followed by (C739), yet there are two SINQ answers that tell us specifically to not use this code for thyroid primaries. Even the first revision of ICD-O-3 still carries the (C739) as part of this code, which goes against SINQ 20110027 and 20081127.
