Patients with HIV are at higher risk of developing
thrombosis than the general population. We present a rare case of a 57-year-old Japanese man with
HIV infection and a
malignant lymphoma. He had
fever with unknown origin and cervical lymph node swelling 2 months before his hospital visit. Because he was positive for the HIV antibody, he was referred to our HIV special outpatient section. HIV
RNA level was found to be 846,680 copies/ml. Therefore, antiretroviral
therapy of DTG/ABC/3TC was initiated. However, the high
fever continued for 7 days
after treatment initiation; moreover, renal dysfunction was progressive. After admission,
antibiotic therapy was initiated, due to which the
fever subsided. However, renal dysfunction continued to progress. Fourteen days later, he died due to
acute renal failure with
hyperkalemia. An autopsy revealed a large mass in the spleen, and histological findings revealed a
diffuse large B cell lymphoma (DLBCL). Furthermore, thrombi were detected in the right and left ventricles, right atrium, iliac artery, and renal artery. Pathological findings revealed that the
thrombus induced the
renal failure. These thrombi contained
fibrin with inflammatory cell infiltration but not
tumor cells. Patients with HIV and
malignant lymphoma are at a higher risk of
thrombosis. It is important to consider
thrombosis during the treatment of patients with HIV.
