Atypical presentation of herpes simplex (chronic hypertrophic herpes) in a patient with HIV infection.
A 46-year-old man with HIV infection and AIDS presented with a large perianal ulcerated vegetative lesion that developed over a 1-year period. He had a past history of recurrent genital herpes infection, treated successfully each time with acyclovir. The perianal lesion developed while he was taking prophylactic acyclovir. Clinically, there were features suspicious of a carcinoma and a biopsy was reported as showing dysplasia. Therefore, the lesion was resected in its entirety. Histologically, there were prominent pseudo-epitheliomatous hyperplasia and chronic ulceration associated with herpesvirus infection. There was no evidence of dysplasia or malignancy. It is important to be aware of chronic vegetant herpesvirus infection, as clinical appearances are unusual and some methods of identification, such as smears or biopsy, may not be sufficient for diagnosis. Viral culture or PCR may need to be performed for a definite diagnosis to alleviate prolonged discomfort and avoid unnecessary radical surgery.
