hiv: an epidemiologic study on head and neck involvement in 50 patients

introduction: acquired immunodeficiency syndrome (aids) is a worldwide infection. because of the vast array of manifestations of aids and its many atypical presentations, it is becoming increasingly challenging for clinicians to accurately diagnose new lesions. materials and methods: in a descriptive cross-sectional study conducted from 2007 to 2010, 50 patients with a proven human immunodeficiency virus (hiv) infection were evaluated. based on the findings of a physical examination and paraclinic tests, hiv signs and symptoms were recorded.   results: the mean (range) age of the patients was 35.45 ±5.24 (5–55) years. forty-two (84%) cases were male and eight were female. the mean duration of carrying the virus was 4.51 ±1.03 years. oral manifestations were the most common (94%), followed by rhinologic (88%), otologic (66%), and finally neck (44%) manifestations.   conclusion:  head and neck presentations are very common in hiv patients; therefore otolaryngologists, as the first physicians who may encounter such patients, should be aware of this condition.
