1 sie 2023 · Vulvar intraepithelial neoplasia 3 is a type of vulvar intraepithelial neoplasia (VIN). VIN is a precancer. This means it’s not cancer but can sometimes develop into cancer. VIN is the growth...
29 mar 2023 · Vulval intraepithelial neoplasia or VIN is when abnormal cells develop in the top layer of skin covering the vulva. It is not vulval cancer but could turn into cancer. This may take many years.
Vulval (or vulvar) intraepithelial neoplasia is a pre-cancerous skin lesion (a type of squamous cell carcinoma in situ) that can affect any part of the vulva. The term vulval intraepithelial neoplasia describes two conditions with different biological behaviour: usual type and differentiated type.
Medically speaking, the term denotes a squamous intraepithelial lesion of the vulva that shows dysplasia with varying degrees of atypia. The epithelial basement membrane is intact and the lesion is thus not invasive but has invasive potential. The terminology of VIN evolved over several decades.
Treatment is recommended for all women with vulvar HSIL (VIN usual type). Because of the potential for occult invasion, wide local excision should be performed if cancer is suspected, even if biopsies show vulvar HSIL.
18 paź 2023 · Vulvar intraepithelial neoplasia (VIN) is a noninvasive squamous lesion and precursor of squamous cell carcinoma of the vulva. This activity reviews the evidence-based approaches to diagnosing and managing VIN and focuses on current advancements in histopathological classification and risk stratification of VIN lesions.
Three developed micro-invasive cancer. Conclusions: Treatment by local excision is both diagnostic and therapeutic. Excision may reveal micro-invasive cancer, patients are usually symptomatic and VIN 3 has some potential to become invasive. Treated patients may develop microinvasive disease but frank invasion was not seen.
