Question:

Primary Site--Soft Tissue: How is the primary site coded for a PNET found in the groin when the Tumor Board states the primary is unknown but the SEER site/histology validation table does not allow a site of C809 or C76x to be coded in combination with the histology of 9473/3?

Discussion:

Answer:

Code site to C495 [connective tissue of pelvis, groin].

This was not called metastatic PNET and no other site of disease is noted. PNET is a broad classification of a group of tumors that usually occur in the CNS and can also occur in soft tissue (neuroblastoma, extra-osseous Ewing sarcoma).
