Reportability--Melanoma: Is an excisional biopsy of the skin with a diagnosis on the pathology report of "Tumoral melanosis" reportable by itself or must there be a pathologist note, such as "Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma", in order for it to be reportable? See Discussion.

Skin, left upper back, exc Bx: Tumoral melanosis. Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma.

If reportable, do we report a diagnosis of tumoral melanosis without a similar note?

Tumoral melanosis (TM) alone is not reportable. It is not listed in ICD-O-3. TM can be associated with a regressed melanoma, but it can also occur with other cutaneous tumors. The case is reportable if there is a diagnosis of melanoma.

20081120 MP/H Rules--Sarcoma: How many primaries should be abstracted for chondrosarcoma of right toe in 2002, of right lower leg in 2006 and right tibia in 2007? See Discussion. A patient had a myxoid chondrosarcoma of the right toe in 2002. This was amputated and staged as T2 - high grade. Patient had a recurrence in the lower right leg in 2006. At this time he had a below knee amputation. The tumor in 2006 was stated to be similar histologically to the 2002 tumor with pathologic comparison done. Then in 2007 the patient presents with pain in right knee and stump. CT says compatible with recurrent disease, but no copies of path sent. Patient then had an above knee amputation, with diagnosis of clinically recurrent chondrosarcoma of tibia. How many primaries should be abstracted? Is 2007 diagnosis a new primary?

For cases diagnosed 2007 or later:

Abstract two primaries in this case, 2002 and 2007.

The first primary was diagnosed in 2002. The 2006 diagnosis would not be a new primary according to the rules in effect at that time (2004 SEER manual, page 11, rule 5, exception 1).

Use the current MP/H rules to compare the 2007 diagnosis to the 2002 diagnosis. Start with rule M3 and stop at rule M10. The 2007 diagnosis is a separate primary.

Reportability--Heme & Lymphoid Neoplasms: Is idiopathic hypereosinophilia reportable? Must the diagnosis include the word 'syndrome'?

Idiopathic hypereosinophilia is not reportable.

Hypereosinophilic syndrome is a different entity and is a synonym for chronic eosinophilic leukemia.

Reportability--Skin: Is this case not reportable if the intranasal polyp is covered with cutaneous epithelium (essentially skin) or, is it reportable as a primary intranasal basal cell carcinoma? I have found one article regarding primary intranasal basal cells, which are described as being "very rare". But, I am not sure whether, in those cases, cutaneous epithelium was found.

FINAL DIAGNOSIS: (A) Nasal cavity, polyp, excision: Sinonasal inflammatory polyp with overlying cutaneous epithelium showing foci of superficial (noninvasive) basal cell carcinoma

Report this case as a basal cell carcinoma, noninvasive, of the nasal cavity, based on the information provided.

The polyp was removed from the nasal cavity (C300) which is a reportable site for basal cell carcinoma.

20091122 MP/H Rules/Multiple primaries-Brain: Does a glioblastoma multiforme following a low grade glioma (oligodendroglioma) represent a new primary? See Discussion.

In 2/08 patient underwent resection of tumor of right frontal lobe. Path diagnosis showed a low grade glioma, favor low grade oligodendroglioma (WHO grade II). In 02/09 biopsy of a left thalamic mass showed glioblastoma mutiforme. Per rule M6 glioblastoma multiforme following a glial tumor is a single primary. Per path diagnosis, the first tumor represented a low grade glioma. However, oligodendroglioma is not on the glial branch of chart 1 in the MP/H rules.

For cases diagnosed 2007 or later, glioblastoma multiforme following oligodendroglioma are multiple primaries according to rule M8. Rule M6 does not apply. M6 applies only to glial tumors as listed in chart 1. Chart 1 is based on the WHO classification. The WHO classification separates oligodendroglial tumors from glial tumors. Brain and CNS N/A 2009
20000511 EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: What codes are used to represent these fields when only a regional lymph node (positive) aspiration is performed?

For cases diagnosed 1998-2003:

With the exception of those sites/histologies that require 99 in these fields, code the Number of Regional Lymph Nodes Positive field to 97 [Positive nodes but number of positive nodes not specified]. Code the Number of Regional Lymph nodes Examined field to 95 [No regional Lymph nodes removed, but aspiration of regional Lymph nodes was performed].

20091121 MP/H Rules/Multiple primaries--Brain: Does a patient diagnosed with anaplastic astrocytoma of the left temporal lobe in 2000 followed by a diagnosis of oligoastrocytoma of the right frontal lobe in 2007 have a single primary per rule M7 or multiple primaries per rule M8? See Discussion. MP/H rule M7 states that tumors with ICD-O-3 histologies on the same branch in chart 1 are a single primary. Chart 1 shows that both of the histologies for our sample case are located on the glial branch. However, the glial tumor branch has three secondary branches. Does rule M7 apply to secondary branches? Anaplastic astrocytoma [9402] is classified under the secondary branch for astrocytic tumors. Oligoastrocytoma [9382] is classified under the secondary branch for mixed glioma. Does rule M7 or does rule M8 apply for this case? Does this case represent one or two primaries?

For cases diagnosed 2007 or later, Rule M8 applies. There are two primaries.

Anaplastic astrocytoma and oligoastrocytoma (mixed glioma) are on separate branches in Chart 1. They are both gliomas, but one is a mixed glioma and the other is an astrocytic tumor.

MP/H Rules/Multiple primaries--Ampulla of vater: Is this a new primary? Patient has intramucosal adenocarcinoma in a tubulovillous adenoma of the ampula of vater in Sept. of 2011. In May of 2012, patient has another ampullary adenoma with intraepithelial carcinoma (pTis) and an area suspicious for invasion. This is coded 8263/3.

Rule M14, Multiple in situ and/or malignant polyps are a single primary, precedes rule M15, An invasive tumor following an in situ tumor more than 60 days after diagnosis is a multiple primary, per the MP rules for 'Other sites',

Rule M14 applies. Abstract this case as a single primary.

20021117 Multiple Primaries (Pre-2007)--Bladder/Prostatic Urethra: Is the prostatic urethra a new primary for a case with a history of recurrent noninvasive bladder cancer that was subsequently diagnosed with transitional cell carcinoma in situ of the prostatic urethra and had a subsequent clinical diagnosis of "refractory bladder carcinoma"?

For tumors diagnosed prior to 2007:

If the histology of the bladder primary is "transitional cell carcinoma" or "papillary transitional cell carcinoma," do not code the prostatic urethra as a new primary. This is probably a case of intraluminal (mucosal) spread of the original tumor, rather than separate primaries. The clinical diagnosis supports this view.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

Reportability--Head & Neck: Would this be reportable and if so what histology would be coded? Soft tissue mass left cheek excision reveals Carcinoma Ex Pleomorphic Adenoma Non-Invasive with focal vascular invasion. Margins clear.

Carcinoma ex pleomorphic adenoma (Ca-ex-PA) is reportable. Assign 8941/3. The WHO classification of head and neck tumors defines Ca-ex-PA as an epithelial malignancy arising in a benign pleomorphic adenoma. Most of these originate in the parotid gland but can also arise in other salivary glands.
