Question


Reportability/Behavior: Is myxoinflammatory fibroblastic sarcoma (MIFS) reportable for 2018?  This histology is on the 2018 ICD-O-3 histology update list with a behavior code of /1. See discussion.



Discussion


This will be a tough one for registrars to recognize as non-reportable since the terminology contains sarcoma, so we just want to double check.



Answer


Myxoinflammatory fibroblastic sarcoma (MIFS) (C49._), 8811/1, is not reportable for 2018 based on the 2018 ICD-O-3 New Codes, Behaviors, and Terms list. This is a new histology/behavior not previously listed in ICD-O-3. According to the WHO 4th Ed Tumors of Soft Tissue & Bone, this histology has been given a benign (/1) behavior; however, if the pathologist and/or physician state the tumor is malignant or metastatic, report the case and assign behavior code /3.
