Malignant Melanoma of Tonsil and Oropharynx

Primary Site Histology Staging Type
C090-C091, C098-C100, C102-C104, C108-C109 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

C090 Tonsillar fossa C091 Tonsillar pillar C098 Overlapping lesion of tonsil C099 Tonsil, NOS (excluding lingual tonsil C02.4) C100 Vallecula C102 Lateral wall of oropharynx C103 Posterior wall of oropharynx C104 Branchial cleft (site of neoplasm) C108 Overlapping lesion of oropharynx C109 Oropharynx, NOS **Note 1:** This schema is based on the UICC chapter *Malignant Melanoma of Upper Aerodigestive Tract,* pages 51-53. * Primary sites C090, C091, C098, and C099 are not listed in this chapter of the UICC manual; however, they are included in this schema and TNM staged. **Note 2:** Laterality must be coded for C090, C091, C098, and C099 **Note 3:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Tonsil, Pharynx* chapter on page 60 of the [SS2000 on-line manual](http://seer.cancer.gov/tools/ssm/SSSM2000-122012.pdf#page=60).
