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:** If verrucous carcinoma (8051/3) is described as noninvasive or as having a broad pushing border or penetration, assign code 050. If verrucous carcinoma is not so characterized, assign code 070, Verrucous carcinoma, NOS. If there is destructive invasion of verrucous carcinoma into structures in code 100 or greater, assign the appropriate higher code. **Note 3:** Tumors limited to the penis (see codes 100, 200, 300) include * Dartos fascia (foreskin) * Dermis (foreskin) * Lamina propria (glans and foreskin) * Subepithelial connective tissue (shaft)
