Background: The authors' objective was to provide a glossary of terminology related to the surgical treatment of invasive vulvar carcinoma. There is currently no consensus in the literature regarding the names of the surgical procedures used to treat this disease., Methods: A surgical glossary should be supported by clear definitions and acceptance of notions related to topographic anatomy that are specific to the surgical practice. A critical review of the classic, chiefly used Italian, French, German, and English textbooks of anatomy revealed some discrepancies and lack of uniformity in descriptions of vulvar and inguinal fascial structures and lymph nodes, which represent the principal landmarks of surgical treatment. In the proposed glossary, the descriptions of these anatomic landmarks integrate classic anatomic knowledge, data from recent gynecologic studies of inguinal anatomy, and the clinical experiences of the authors., Results: The glossary is composed of 16 surgical definitions, which are divided into 3 main sections of terminology describing the surgical treatment of the: 1) vulva, 2) inguinal lymph nodes, and 3) pelvic lymph nodes. The fundamental objective behind the glossary is to describe the area and the depth of the surgical procedure. Three determinants of the area (local, partial, and total) and three determinants of the depth of surgery (superficial, simple, and deep) were used to arrive at the fully articulated definitions in the glossary., Conclusions: The authors are aware that the proposed glossary should not be considered a definitive one; however, it could serve as a good basis for further debate. The terms employed in the glossary are accompanied by anatomic and descriptive references to help avoid confusion and promote better understanding among gynecologic oncologists who are involved in the treatment of vulvar carcinoma.

The aim of this paper is to update the physicians (gynecologists, dermatologists and pathologists) on the evolution of vulvar disease terminologies. In doing that the authors illustrate briefly the fundamental steps which led to present classifications of the International Society for the Study of Vulvar Disease (ISSVD). The classification of "non neoplastic epithelial disorders" together with that of "intraepithelial alterations" are illustrated and compared with the terminologies previously employed. The last ISSVD definition of "superficially invasive carcinoma" of the vulva is also presented and discussed. The authors concluded that even if all these ISSVD classifications represent an important effort for reaching a common language for a better international exchange of different experiences, nevertheless an improvement of these terminologies is still requested.

The data on the natural history of vaginal intraepithelial neoplasia (VaIN) available in the literature are scarce and incomplete. As a matter of fact the majority of the Authors report series with a small number of cases, which are predominantly represented by VaIN III and usually already treated. Nevertheless from the review of the literature it seems that VaIN, particularly those of low grade (I-II), tend to show a high rate of spontaneous regression. The lesions are frequently multifocal, associated with papilloma virus (HPV) infection and arising in young women. On the contrary, the VaIN showing a more aggressive behaviour are usually represented by single lesions, arising in older women. Those patients are also frequently immunosuppressed, with a history of preceding genital neoplasia and a previous exposure to radiation and/or chemotherapy.

The authors reviewed 21 cases of "mild vulvar atypia" diagnosed from 1981 to 1990. The first 16 cases were diagnosed as hyperplastic dystrophy with mild atypia according to the 1976 ISSVD Classification of Vulvar Disease, while the last five cases were diagnosed as vulvar intraepithelial neoplasia grade I (VIN I). The review of the specimens was made by the same pathologist who gave the initial diagnosis and by a dermatopathologist unaware of the initial diagnosis. Both reviewers used the 1986 and 1989 ISSVD terminologies. The presence of "mild atypia" was confirmed in only four of the 21 specimens, that is in 19% of the cases, and two of them were found in the context of patients suffering from a lichen planus. These findings show that the diagnosis of mild atypia in vulvar tissues is a challenge and that mild vulvar atypia cannot be automatically considered a VIN I.

Thirty-two women with histologically confirmed cervical intraepithelial neoplasia (CIN) associated with human papillomavirus (HPV) infection were treated with intralesional beta-interferon. At 12 months from the end of the treatment, 60% of the patients showed complete regression, histologically assessed, of CIN. Considering separately the different CIN grades, the regression for CIN I was 71%, 64% for CIN II and 45% for CIN III. Side-effects were rather frequent (84%) but they did not require discontinuation of the treatment. On the basis of these data the Authors believe that intralesional beta-interferon, in selected cases, can play a role, as a conservative modality, among the different techniques of CIN therapy.
