RESUMO
Non-Hodgkin's Lymphoma (NHL) in people living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) still constitutes a reality of high morbidity and mortality, sometimes not respecting the patient's degree of immunosuppression as it can even occur in those with a high CD4+ T lymphocyte count. Burkitt's lymphoma, in this sense, has been shown to be one of the main subtypes of this condition in this group of patients. This case report concerns a 32-year-old man diagnosed with metastatic gastric Burkitt's lymphoma after one month of his admission to a tertiary hospital for neurological complaints. The aim of this study is to raise an alert to suspect this diagnosis even in patients with adequate immunity, a well-done history, and a physical examination, which are the main pillars for reaching a diagnosis.
