What are the different stages of kaposi sarcoma?

Skin vs. visceral: There are no specific stages, but the earliest form of ks is usually cutaneous (skin lesions), which can be mild or severe depending on how extensive it is. People with extensive ks or more advanced immunosuppression can develop visceral ks: involvement of internal organs such as the GI tract or lungs. Of those, lung involvement is usually has the worst prognosis.
