TCHERNEV, Georgi. Sexually transmitted papillomavirus infections: epidemiology pathogenesis, clinic, morphology, important differential diagnostic aspects, current diagnostic and treatment options. An. Bras. Dermatol. [online]. 2009, vol.84, n.4, pp.377-389. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962009000400009.
The family of human papilloma viruses (HPV) comprises more than 100 genotypes. Approximately 30 of the genotypes are responsible for infections in the human anogenital area. A precisely defined algorithm with the goal of diagnosing and removing HPV for a prolonged or indefinite length of time, as well as to protect the patient from any malignant ransformation, does not currently exist. The identification of HPV strains by PCR or DNA hybridization in lesional tissue provides higher security for the patients. In high-risk patients additional colposcopy, rectoscopy, and rethroscopy/cystoscopy increase the probability of proper diagnosis and the application of a reliable therapeutic strategy. Removal of lesions by means of invasive methods, such as electrodessication, cryosurgery, and/or laser therapy, may be successful and could be combined pre- and postoperatively with the local application of podophyllotoxin, Trichloroacetic acid, 5-fluorouracil epinephrine gel, imiquimod, cidofovir or interferon. The administration of vaccine to young patients prevents to a significant extent the clinical manifestation of the most frequent viral strains, being HPV-6,-11 and -18. The different therapeutic methods must be applied in accordance with the clinical picture, taking into account the patient's general status, the presence of concomitant diseases, as well as the local and systematic compatibility of the side effects of each remedy. The review focuses on the diagnosis and treatment options of sexually transmitted HPV-infections and includes synopsis of the most recent literature regarding new data of epidemiology, pathogenesis, ifferential diagnosis and morphology of HPV infections in humans.
