ICD-O-3, 24, 57, 152. Rule A

Question:

Multiple Primaries (Pre-2007)--Soft Tissue: Does SEER agree that one primary of the soft tissues of pelvis [C49.5] should be reported when a pathologic diagnosis for bilateral herniorrhaphies is "right and left inguinal hernias with low grade spindle cell sarcoma"?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Yes. This is one primary and should be coded to C49.5 [Connective, subcutaneous and other soft tissue of pelvis]. According to Rule A in ICD-O-3, the type of tumor ("sarcoma") indicates origin from a particular tissue, resulting in the primary site code of C49.5 [Inguinal region, NOS] for this sarcoma.

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.
