Clinical case: the case of a 48-year-old male patient with a history of HIV on HAART for 15 years, who was admitted for an outpatient infectious disease clinic due to violaceous nodular lesions in the right and left MMII, upper eyelid. left and oropharynx. During hospitalization, a blood culture report was obtained that was positive for Bartonella and a biopsy result of a lower limb lesion concluded that Kaposi's Sarcoma was present. Upper gastrointestinal endoscopy and chest and abdominal tomography were performed, which showed the visceral and systemic involvement of Kaposi's Sarcoma. The HIV genotype is performed, resulting in resistance to antiretrovirals, so the medication is changed and chemotherapy is started, with the patient showing a good response and improvement.
