Notes
**Note 1:** Over 90% of penile cancers are squamous cell carcinomas arising in the skin. Other cancers arising in the skin include adenocarcinomas (5%) arising in sweat glands, melanomas (2%, included in the Melanoma schema), and basal cell carcinoma (2%). About 1% of penile cancers are sarcomas, arising in subcutaneous connective tissues. **Note 2:** Verrucous carcinoma (M-8051) is a locally aggressive, exophytic, low grade carcinoma with minimal metastatic potential. **Note 3:** Assign Ta if a verrucous carcinoma is described as noninvasive or as having a broad pushing border or penetration. * If there is destructive invasion of verrucous carcinoma into structures in T1 or greater, assign the appropriate higher code **Note 4:** Information about involvement of the corpus spongiosum or corpus cavernosum is collected in this field for anatomic staging. This information is also collected in **Site-Specific Factor 10, Involvement of Corpus Spongiosum/Corpus Cavernosum** because involvement of these structures may have an independent effect on prognosis.NAACCR Item
