Unlike the United States and Africa, the impact of HIV infection on the prevalence of tuberculosis has not been emphasized in Taiwan. Nevertheless, we encountered four patients in whom cervical tuberculous lymphadenitis was their main early symptom, and HIV infection was later diagnosed. It is important in clinical medicine and public health to know that many HIV carriers are among the crowds of patients with tuberculosis. In other words, when a patient presents with a neck mass in conjunction with any HIV-infection risk factors or immunodeficiency symptoms, HIV-related lymphadenopathy must be included in the differential diagnoses. We propose that serologic tests for HIV infection be performed in patients with tuberculous lymphadenitis especially in those with known risk factors of HIV. In this way, patients who have been coinfected with tuberculosis and HIV can be discovered and treated at an early stage.[SDGs]SDG3acquired immune deficiency syndrome; adult; article; case report; cervical lymph node; disease association; human; Human immunodeficiency virus infection; human tissue; lymph node biopsy; lymphadenitis; lymphadenopathy; male; tuberculosis; tuberculous lymphadenitisjournal article2-s2.0-0036129709
