Reportability/Behavior: Is the following reportable, and if so, what is the histology code? Final Diagnosis (on multiple conjunctive excisions): Conjunctiva - primary acquired melanosis with atypia (see note). Note: "In all 3 specimens the process extends to the margins of excision. Complete extirpation is recommended (primary acquired melanosis with atypia is considered melanoma in situ).

Reportability--Bladder: Please explain the reportability of UroVysion for bladder cancer in the following circumstances.
1. Patient has positive UroVysion test and follow up biopsy is negative. Is this case reportable with a diagnosis date the date of the UroVysion?
2. Patient has positive UroVysion test and follow up biopsy is positive for cancer. Is the diagnosis date of the date of the positive UroVysion or the date of the positive biopsy? Thank you.

Reportability/Histology: Would a histology reading "Well-differentiated neuroendocrine neoplasm" of the appendix be reportable? Since the word "tumor NOS" and "neoplasm NOS" both code to 8000, I would assume they would be interchangeable but just wanted to verify.
According to SINQ 20130027 & 20140002 a "Well-differentiated neuroendocrine tumor" of the appendix IS reportable.

Multiple primaries--Heme & Lymphoid Neoplasms: Should the 2014 diagnosis be abstracted as a new primary since it is not mantle cell lymphoma and all of the types listed in the differential diagnosis would be a new primary? See discussion.

Reportability--GIST: The 2014 SEER Program Coding and Staging Manual and the answer to SINQ 20100014 appear to conflict with respect to reporting GIST cases. The manual states (p.5, exception 1) that we are to accession the case if the patient is treated for cancer. However, the patient in Example #7 in the SINQ discussion is receiving chemotherapy, but is deemed not reportable. This is a problematic issue in our area, as pathologists prefer using the NCCN “Risk Stratification of Primary GIST by Mitotic Index, Size and Site” table rather than stating whether the tumor is benign or malignant. Although they tell us that moderate or high risk should receive treatment, they will not characterize them as malignant.

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',

MP/H Rules/Multiple primaries--Colon: Does rule M7 apply here (A frank malignant or in situ adenocarcinoma and an in situ or malignant tumor in a polyp are a single primary)? Can the frank malignant adenocarcinoma be any specific type of adenocarcinoma for this rule to apply?
A patient has 2 synchronous tumors in the ascending colon. The first is grade 3 adenocarcinoma with signet ring differentiation and focal mucinous features (8255/3). The second is grade 2-3 adenocarcinoma in a tubulovillous adenoma (8263/3).

Histology--Heme & Lymphoid Neoplasms: Should the 1995 diagnosis be changed to plasmacytoma? A 1995 case on the central registry database indicates that MRI and bone surveys revealed a pubic ramus lesion that was biopsied. There are no other bone lesions. A bone marrow biopsy was negative. The pathologist's diagnosis at that time was "Plasma Cell Myeloma". In 2013 there was a positive bone marrow biopsy and a diagnosis of Plasma Cell Myeloma. In 2013, a history of "sequential plasmacytomas since 1995" was mentioned. Since the 1995 diagnosis was only a solitary bone lesion with no marrow involvement, it certainly seems to fit a diagnosis of plasmacytoma better than myeloma.

MP/H Rules/Multiple primaries--Thyroid: How many primaries should be reported when a complete thyroidectomy specimen shows two tumors: 1.8 cm papillary carcinoma with tall cell features (8344/3) and a 0.4 cm papillary thyroid carcinoma (8260/3)? See discussion.
