Malignant Melanoma of Nasopharynx (including Pharyngeal Tonsil)

Primary Site Histology Staging Type
C110-C113, C118-C119 8720-8790 TNM 7 and Summary Stage

If you are working with a site/histology that only summary stages and you need to directly code it, please use the SEER Summary Stage 2000 manual

Notes

C110 Superior wall of nasopharynx C111 Posterior wall of nasopharynx (including pharyngeal tonsil) C112 Lateral wall of nasopharynx C113 Anterior wall of nasopharynx C118 Overlapping lesion of nasopharynx C119 Nasopharynx, NOS **Note 1:** This schema is based on the UICC chapter *Malignant Melanoma of Upper Aerodigestive Tract,* pages 51-53. **Note 2:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Nasopharynx* chapter on page 62 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=62).
