The histological appearance is that of epidermoid carcinoma in situ, therefore Bowenoid papulosis may be considered an intraepithelial neoplasia. Although high-risk human papillomaviruses HPV 16, 18, 31, 33, 39 are responsible for its etiology, most human papillomavirus brochure are benign and regress spontaneously.

The treatment of Bowenoid papulosis consists in the medical or surgical removal of the lesions.

Human papillomavirus brochure afecþiunea a fost cunoscutã ºi sub alte denumiri precum boala Bowen BB multicentricã [2], papule pigmentate ale human papillomavirus brochure [3], acantoza cu displazie, displazie bowenianã, atipie vulvarã reversibilã [4], carcinom in situ vulvar. Denumirea de PB a fost The name Bowenoid papulosis BP was first introduced by Wade and Ackerman in human papillomavirus brochure describe clinical lesions similar to acuminate condyloma but with the histological appearance of intraepithelial neoplasia IENidentical to that of Bowen s disease [1].

The disease was initially known under various names such as multicentric Bowen s disease BD [2], pigmented penis papules [3] acanthosis with dysplasia, Bowenoid dysplasia, reversible vulvar atypia [4] or vulvar carcinoma in situ.

Epidemiologie Nu existã studii epidemiologice privind PB, dar leziunile apar mai frecvent la subiecþii imunodeprimaþi îndeosebi la pacienþii HIV pozitiv. Aspect clinic Papuloza bowenoidã afecteazã îndeosebi pacienþi tineri, pruritul fiind simptomul revelator într-o treime din cazuri. Leziunile sunt în general multiple, dispuse simetric, izolate dar uneori confluate în placarde cu pãstrarea individualitãþii, localizate la nivelul organelor genitale human papillomavirus brochure.

La femei ºi la pacienþii HIV pozitiv leziunile se pot extinde pe regiunea perinealã, perianalã sau chiar în canalul anal.

Oncogenic HPVs can be involved in Bowen s disease, a few vulvar and penile cancers human papillomavirus brochure well as intraepithelial and invasive cervical neoplasia [6,7], thus suggesting the common etiology of the histological changes present in these diseases Table I.

Management The clinical diagnosis of Human papillomavirus brochure, which is based on the young age rectosigmoid cancer pathophysiology the patient and the multiple, multifocal lesions detected, requires a biopsy for the histological determination human papillomavirus brochure IEN, regardless of the clinical form.
