We report a case of a KS in homosexual man with AIDS that was originally presented and diagnosed as UC. We report a 31-year-old homosexual man who presented with rectal pain and bleeding and was found to have Kaposi sarcoma in both skin and rectum. [omicsonline.org]

At physical examination he presented with an excellent general state, without skin lesions or palpable adenopathies. Rectal digital examination detected an irregular and painful rectal mass with rough consistence. [scielo.isciii.es]

No evidence of non-Hodgkin lymphoma was present on lymph node or bone marrow biopsies. [ncbi.nlm.nih.gov]

Cases with widespread visceral involvement are commonly poorly responsive to treatment. UC is a chronic inflammatory bowel disease that affects large bowel, causing inflammation and ulcers. [omicsonline.org]

Five patients with advanced AIDS received no specific treatment for anorectal KS. Follow-up ranged from 1 month to 5 years. [pubmed.ncbi.nlm.nih.gov]

KS can have four epidemiological variants: classic, African or endemic, iatrogenic or related to immunosuppressive treatment, and epidemic or AIDS-related [11]. HHV-8 is the main etiological agent of the four clinical-epidemiological forms of KS. [omicsonline.org]
