Résumé
Burkitt lymphoma [BL] is the second most common AIDS-related lymphoma. Primary sinonasal BL in HIV patients is extremely rare and treatment data in this subset of patients is almost nonexistent. Recently, a few studies reported promising results treating HIV-associate BL with an intensive chemotherapy regimen. The use of highly active antiretroviral therapy [HAART] concomitantly with chemotherapy seems to improve patient outcomes, but this topic is still controversial due to potential drug interactions. We report a case of a 29-year old woman diagnosed with AIDS presenting with symptoms of chronic sinusitis. Subsequent investigation by CT scan and endoscopic biopsy discovered a sinonasal BL in an early stage. The patient was treated with intensive chemotherapy and HAART and achieved a complete remission and long-term immunologic recovery. This case report describes a rare entity whose natural history, treatment and prognosis is infrequently characterized in the medical literature
