Genital and Perianal Herpes Simplex Simulating Neoplasia in Patients with AIDS

Abstract Genital and perianal herpetic ulcers are common in HIV-infected patients and chronic mucocutaneous ulcers persisting for more than 1 month are the hallmark of active AIDS status. However, atypical clinical manifestations of herpes simplex virus (HSV) may occur in immunocompromised patients presenting as tumor-like nodules or condylomatous or hypertrophic lesions, rather than a classic ulcer. Such unusual presentations raise the risk of misdiagnosis and a delay in appropriate treatment. Here we describe nine immunocompromised HIV-positive patients with CD 4 count ranging from 14–362/mm3 (mean 170/mm3), with unusual tumoral presentation of anogenital herpes. There were six male and three female patients with AIDS with mean duration of HIV infection of 14 years. All of the patients had history of highly active antiretroviral therapy (HAART), with five patients compliant with the therapy at the time of biopsy. Six patients presented with scrotal or vulvar masses and three with perianal nodules. Five ...
