SEER Inquiry System - Question 20051056 Details

For tumors diagnosed prior to 2007:

The ICD-O-3 histology code is 8811/3 [Fibromyxosarcoma] according to the WHO Classification of Tumours of Soft Tissue and Bone. WHO defines myxoinflammatory fibroblastic sarcoma (MIFS) as "a unique low grade sarcoma with myxoid stroma, inflammatory infiltrate and virocyte-like cells that predominantly involves the hands and feet."

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
