EOD Primary Tumor

This input is used for staging

Notes

**Note 1:** In the United States and Canada, Kaposi sarcoma is usually an illness related to Acquired Immunodeficiency Syndrome (AIDS) which affects primarily the skin; however, lesions may also form in the connective tissue, mucosa (e.g. oral cavity) or visceral organs (e.g. lungs). For connective tissue tumors (C49._), use extension codes for skin. **Note 2:** Choice of EOD Primary Tumor for Kaposi sarcoma depends on number and location of lesions. For example, code 100 (Localized) for a single or multiple lesions involving skin. Code 200 (Regional) for any number of lesions involving both skin and viscera.
