Which condition involves inflammation and epithelial thinning of the anogenital area, mostly affecting postmenopausal women?

Lichen sclerosus is a chronic inflammatory condition that primarily affects the anogenital area, particularly in postmenopausal women. It is characterized by distinct changes such as inflammation, epithelial thinning, and white patchy lesions on the skin. The condition often presents with symptoms including itching, pain, and discomfort, and it can lead to significant scarring and narrowing of the vaginal opening if left untreated.

The demographic predominance in postmenopausal women makes this condition particularly notable, as hormonal changes during this period may contribute to its pathophysiology. The inflammation associated with lichen sclerosus can damage the integrity of the skin and mucosal surfaces, leading to the characteristic thinning observed in affected individuals.

In contrast, other options represent different conditions with distinct presentations and implications. Vulvar intraepithelial neoplasia is a premalignant condition related to HPV infection that may involve disordered epithelial growth rather than inflammation and thinning. Cervical cancer primarily affects the cervix and is linked to HPV as well, showing differing clinical features. Vulvar psoriasis typically presents with a well-defined erythematous plaque with silvery scales, which is not characteristic of the changes seen in lichen sclerosus.

Thus, the features of
