Genital Warts HPV Subclinical Lesions

Subclinical lesions

Subclinical lesions of the external anogenital skin are not seen by the naked eye, but are sometines detectable by soaking the skin with 5% acetic acid and examining with a colposcope. These lesions are usually asymptomatic, but may cause irritation and inflammation of the skin. The test is not specific. Many aceto-white lesions are not caused by human papilloma virus. It is not recommended that these subclinical lesions be sought unless there is a clinical indication for doing so. False positive results are commonly due to inflammatory conditions such as, lichen sclerosus et atrophicus, lichen planus, psoriasis, vulvovaginitis, eczema, genital herpes, and traumatic abrasions.
