Question:
Reportability/Histology--Pancreas: According to SINQ 20140058, solid pseudopapillary neoplasm of the pancreas is reportable (as of 2014). However, per ICD-O-3.2, this histology is not reportable until 2021+. Please clarify which is correct and clearly state the timeframe that it was reportable or not reportable.
Discussion:
Answer:
Solid pseudopapillary neoplasm of the pancreas is reportable for cases diagnosed in 2014 and later. Report solid pseudopapillary neoplasm of the pancreas (8452/3) as the guidance in SINQ 20140058 is still in effect.
The 4th and 5th editions of the WHO Classification of Tumors of the digestive system define solid pseudopapillary neoplasm of the pancreas as a low-grade malignant pancreatic tumor.
