Question:
Reportability--Is "intraductal papillary mucinous neoplasm with low grade dysplasia" (also called IPMN adenoma) reportable? See Discussion.
Discussion:
According to the ICD-O-3, the histology for IPMN adenoma is 8453/0 is non-reportable. However, per SINQ 20021099, this is reportable.
Answer:
Intraductal papillary mucinous neoplasm (IPMN) of the pancreas with low grade dysplasia, also referred to as IPMN adenoma, is not reportable.
IPMN of the pancreas is reportable when stated as "IPMN with high-grade dysplasia," or "IPMN with an associated invasive carcinoma," or "IPMN with an associated in situ carcinoma."
The case in SINQ 20021099 is stated to have "multifocal high grade dysplasia (so-called borderline tumor and carcinoma in-situ)" and is reportable because there is an explicit statement of carcinoma in situ, not because of the reference to the presence of high grade dysplasia. It is coded 8453/2 [Intraductal papillary-mucinous carcinoma, non-invasive].
