Reportability/Histology--Skin: Is 'skin, left temporal scalp, low grade adnexal carcinoma, probable sweat gland origin' reportable as 8400/3, skin of temple?
Assign 8390/3 for adnexal carcinoma of skin. 8390/3 is reportable, including 8390/3 of skin.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported for a patient with a 6/5/12 RUL biopsy that is positive for MALT lymphoma and a 6/7/12 cervical lymph node biopsy that is positive for follicular lymphoma?
Per Rule M15, abstract two primaries for this case. According to M15, use the Heme DB Multiple Primaries Calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. The result is two primaries, MALT lymphoma [9699/3] and follicular cell lymphoma [9690/3].

Histology--Breast: Please confirm the morphology code for a diagnosis of "encapsulated papillary carcinoma" of the breast. Several articles on the internet lead me to believe it is the same as an intracystic carcinoma, code 8504/2 (our case shows no evidence of invasion).
You are correct in coding 8504/2 for this case. Per the 4th Edition WHO Tumors of the Breast, encapsulated papillary carcinoma (EPC) of the breast is synonymous with intracystic or encysted papillary carcinoma. It is a variant of ductal carcinoma in situ (DCIS).
Reportability--Hematopoietic, NOS: The Abstracting and Coding Guide for the Hematopoietic Diseases, page 47, states to determine whether the physician is using the term myelodysplasia to describe bone marrow marrow malfunction or a neoplasic syndrome in order to determine reportability. What do we do when there is no information one way or the other?
For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Primary Site--Heme & Lymphoid Neoplasms: How is the primary site coded for a B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma when a biopsy of the paraspinal muscle and epidural tissue is positive, but there is no indication of lymph node involvement in the chart?
Code the primary site to soft tissue of the back, NOS [C496] per Rule PH24 and the Abstractor Notes in the Heme DB for B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.
Code the primary site to the organ when lymphoma is present only in an organ. The lesion is described as epidural (tissue surrounding the dura) and involving paraspinal muscle, NOS. Both are connective or other soft tissues of the trunk, NOS [C496].
B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is a synonym for DLBCL 9680/3. When there is no primary site listed in the Heme DB, go to the Abstractor Notes. In the Abstractor Notes section it states that patients present with lymphadenopathy OR mass lesions in extranodal sites.

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?
Follow rule H3 and code squamous cell carcinoma for these cases unless you can obtain confirmation that these cases should be coded keratinizing squamous cell carcinoma from the lab and/or pathologist. Document this confirmation in your policies and procedures.
The MP/H rules were written with input from leading pathologists in each specialty area. Based on their expert opinion, we instruct registrars to code histology based on the information in the final diagnosis. The microscopic description may contain other terms, but the pathologist lists only the pertinent terms in the final diagnosis.
MP/H Rules/Histology--Bladder: What is the correct histology code for a diagnosis of urothelial plasmacytoma carcinoma of the bladder per pathology report?
Assign code 8120/3, urothelial carcinoma, NOS, to urothelial plasmacytoma carcinoma of the bladder. The WHO classification describes plasmacytoid variants of urothelial carcinoma. There is no specific ICD-O-3 code for these variants; however, and 8120/3 must be used.
Reportability/AmbiguousTerminology: Because there is a caveat in the SEER PCM, 3rd edition to ignore adverbs such as "strongly" when assessing reportability, should a term such as "likely" cancerous be reportable given than the expression "most likely" cancerous is reportable?
"Likely cancerous" is NOT reportable.
The CoC, NPCR and SEER have agreed to a strict interpretation of the ambiguous terms list. Terms that do not appear on the list are not diagnostic of cancer.
EOD-Extension--Lymphoma: What code is used to represent this field for a lymphoma that involves the spleen and lymph nodes above the diaphragm (e.g., involvement of only the spleen below the diaphragm and cervical lymph nodes above the diaphragm)?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 32 [30 + involvement of the spleen; III S]. The spleen is counted twice (once as the spleen and a second time as a lymph node region below the diaphragm). As a result, the EOD-Extension field is coded to reflect involvement of lymph node regions on both sides of the diaphragm plus involvement of the spleen. See Note 1 on the EOD scheme that states "Any lymphatic structure is to be coded the same as a lymph node region."
Laterality--Breast: Should laterality be coded to 9 [Paired site but no information concerning laterality] or to the side with the positive lymph nodes for a case in which no breast mass is found but positive axillary lymph nodes are found on only one side?
Code laterality of the primary site to the side with the positive nodes when there are unilateral positive nodes and the laterality of the primary site is otherwise unknown.
