Observations: A 14-year-old African American female diagnosed with AIDS developed a painless iris mass in the right eye for 10 months. Iridocyclectomy was performed, and the pathology indicated EBV-associated iris smooth muscle tumor with epithelioid morphology. Immunohistochemical stains and in situ hybridization for EBV-encoded ribonucleic acid are very useful diagnostic tools for definite diagnosis. At 14-month follow-up, the patient did not have any tumor recurrence. Conclusion: This is the case report of EBV-associated iris smooth muscle tumor in a person diagnosed with AIDS with a unique epithelioid morphologic feature.

Use of human papillomavirus DNA, E6/E7 mRNA, and p16 immunocytochemistry to detect and predict anal high-grade squamous intraepithelial lesions in HIV-positive and HIV-negative men who have sex with men

Background: Men who have sex with men (MSM) are at high risk of having anal cancer. Anal high-grade squamous intraepithelial lesion (HSIL) is the precursor of anal cancer. We explored the use of different biomarkers associated with human papillomavirus (H
