ICD-O-3 update
Question:
Reportability--Vulva: Is well differentiated vulvar intraepithelial neoplasm (dVIN) reportable? See Discussion.
Discussion:
Is this histologic terminology synonymous with 8071/2 Differentiated-type vulvar intraepithelial neoplasia?
Per the 7/20/2018 updates to the 2018 ICD-O-3 Histology list, the reportability flag was changed from N to Y for Differentiated-type vulvar intraepithelial neoplasia as well as Differentiated penile intraepithelial neoplasia, both 8071/2. It appears that both SINQ 20180020 and the second half of SINQ 20160069 are no longer valid and should be deleted.
Answer:
Report well-differentiated vulvar intraepithelial neoplasm (8071/2). Our expert pathologist consultant regards this as reportable. Well-differentiated is synonymous with differentiated in this context.
The older SINQ questions have been removed.
