EOD Primary Tumor
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 the number and location of lesions * Code 100 (Localized) is for a single lesion involving one of the following: skin, mucosa or viscera * Code 200 (Localized) is for multiple lesions involving one of the following: skin, mucosa or viscera * Code 300 (Regional) is for multiple lesions involving a combination of skin, mucosa or viscera| Code | Description | SS2018 T |
