PG - 126-130 LID - S0385-8146(16)30160-2 [pii] LID - 10.1016/j.anl.2016.05.011 [doi] AB - We present two cases of an HIV-associated parotid gland cyst. One case was a 36-year-old HIV infected woman. She was diagnosed with HIV infection and presented with slowly enlarged parotid gland cysts together with elevation of HIV viral RNA copies/mL in her serum. She was performed parotid gland biopsy under the general anesthesia. The histopathologic analysis revealed negative HIV p24-antigen in her parotid gland tissue. The other case was a 43-year-old man found his parotid gland swelling shortly after highly active antiretroviral therapy (HAART). He was diagnosed with HIV infection 2 years previously. He had started HAART several days before. He showed exceeding elevation of IgE in his serum. We treated him with medication using anti-histamic drugs for his cyst. A computed tomography scan revealed a complete response of his parotid gland cyst 4 weeks after the medication. His serum IgE level was decreased to half of the level before the medication. These findings suggested that the parotid gland swelling associated with HIV was due to various factors including immune reconstitution inflammatory syndrome (IRIS). In case such a parotid gland swelling, we could avoid invasive treatments. CI - Copyright (c) 2016 Elsevier Ireland Ltd. All rights reserved.
