Erosive Lichen Sclerosus-A Clinicopathologic Subtype.

OBJECTIVE: The aim of the study was to identify whether erosive lichen sclerosus (LS) is a distinct clinicopathologic subtype. MATERIALS AND METHODS: The pathology database was searched for "erosion," "erosive," "ulcer," and "lichen sclerosus." Inclusion criteria were histopathologic diagnosis of LS and erosion or ulcer overlying a band of hyalinization and/or fibrosis. Exclusions were concurrent neoplasia and insufficient tissue. Histopathologic review documented site, epithelial thickness, adjacent epidermal characteristics, infiltrate, and dermal collagen abnormality. Clinical data included demographics, comorbidities, examination findings, microbiologic results, treatment, and response. RESULTS: Ten examples of erosive LS and 15 of ulcerated LS occurred in 24 women with a mean age of 67 years. Ulcerated LS was associated with diabetes and nontreatment at time of biopsy. Clinicians identified red patches in all but 1 case of erosive LS. Ulcerated LS was documented as fissure, ulcer, or white plaque, with 8 (53%) described as lichenified LS with epidermal breaches. Erosive LS favored hairless skin with normal adjacent stratum corneum sloping gently into erosion, whereas most ulcers in LS had an abrupt slope from hair-bearing skin. All cases were treated with topical steroids; 2 patients with erosive LS and 10 with ulcerated LS also had oral antifungals, topical estrogen, antibiotics, and/or lesional excision. Treatment yielded complete resolution in 50%. CONCLUSIONS: Erosive LS is an unusual clinicopathologic subtype characterized by red patches on hairless skin seen microscopically as eroded epithelium overlying a band of hyalinized or fibrotic collagen. In contrast, ulcerated LS is usually a traumatic secondary effect in an uncontrolled dermatosis.

Diagnosis of vulval inflammatory dermatoses: a pathological study with clinical correlation.

Diagnosis of vulval inflammatory disease is difficult. In this study, we reviewed 31 vulval biopsies from 23 patients with clinical follow-up. We devised 2 scoring systems from recent publications to determine whether these could help to distinguish between lichen sclerosus (LS) and lichen planus (LP). We found that scoring systems could help in distinguishing LS from LP but that they were no better than using some select pathologic criteria, and were much more time-consuming. Most cases of LS had characteristic dermal sclerosis. LP cases had a characteristic band-like inflammatory infiltrate and did not always have features such as pointed rete ridges, wedge-shaped hypergranulosis and cytoid bodies as observed in nonvulval sites. Eczema was the third most common dermatosis in the study and had features that could also be observed in LS, such as acanthosis, abnormal collagen, and ectatic blood vessels. However, dermal sclerosus was not observed. Loss of dermal elastin fibers was observed in both LS and LP and thus did not help in discriminating between the 2 conditions. Oral LP elsewhere in the body was common and was observed in 20% of both the LS and LP group. A small proportion of patients did not fit into any category. We believed that it was important not to label patients as having a disease unless specific features were observed. It may be in their best interests to be called nonspecific rather than being put in the wrong disease category.

The vulvar dermatoses.

INTRODUCTION: Dermatologic diseases of the vulva may cause dyspareunia. These disorders may be overlooked by gynecologists and urologists because of lack of residency training experience. Dermatologists who are most familiar with these diseases are infrequently trained in vulvovaginal examination. As such, these disorders are often improperly diagnosed and treated. AIM: To describe the presentation and management of the major vulvar dermatoses including irritant and allergic contact dermatitis, lichen sclerosus, lichen simplex chronicus, and lichen planus. MAIN OUTCOME MEASURE: Data from a peer review literature search on the topic of vulvar dermatoses. METHODS: The literature for this review article was obtained through a Medline search. Appropriate dermatology textbooks were utilized for additional information. RESULTS: A comprehensive survey of the vulvar dermatoses. CONCLUSION: Vulvar dermatoses must be considered a part of the differential diagnosis of any woman with a sexual pain disorder. As such, healthcare providers who evaluate and treat women with dyspareunia must become familiar with the most common dermatologic disorders of the vulva.

[New histological terminology of vulvar intraepithelial neoplasia]. / Nouvelle terminologie histologique des néoplasies intraépithéliales de la vulve.

The International Society for the Study of Vulvar Disease (ISSVD) recommends not to use a grading any more and to include in the term vulvar intraepithelial neoplasia (VIN), usual type, the previously called VIN 2 where the nuclear atypia and mitotic figures are confined to the basal half of the epithelium and VIN 3 where nuclear abnormalities and abnormal mitotic figures are present throughout most or all of the thickness of the epithelium. VIN, usual type, is related to a human papillomavirus (HPV) high-risk type infection in most of the cases. The histologic changes previously encompassed within the term VIN 1 will be described as flat condyloma or HPV effect. The less common type of VIN lesion is termed VIN, differentiated type, previously called "high grade" differentiated type or VIN simplex type. This type of VIN is a highly differentiated lesion. The atypia is confined to the basal and parabasal layers of the epithelium, where the cells have abundant cytoplasm and form abortive pearls and the nuclei are relatively uniform in size and contain coarse chromatin and prominent nucleoli. The epithelium does not contain koilocytosis because it is not associated with HPV. It is seen primarily in older women, with a previous history of lichen sclerosus. The diagnosis is often made late in association with keratinising squamous cell carcinomas.

Intralesional injection of triamcinolone in the treatment of lichen sclerosus.

OBJECTIVE: To assess intralesional vulvar injections of triamcinolone as an alternative to using topical treatment. STUDY DESIGN: This was an open trial, in eight patients, of intralesional injection of triamcinolone in patients with symptomatic lichen sclerosus who could not use primary topical treatments. The patients' pretreatment and posttreatment clinical symptoms and gross physical findings were reviewed. In some patients pretreatment and posttreatment biopsies were performed. RESULTS: There was a decrease in severity scores in the categories of symptoms and physical findings. In four patients who consented to posttreatment biopsy, there was a decrease in severity scores on histopathologic findings. CONCLUSION: Intralesional injection of triamcinolone hexacetonide into sites of vulvar lichen sclerosus seems to be an effective alternative to using topical agents.

Lichen sclerosus's pathogeny, the most frequent vulvar dystrophy predominant at the start of menopause, is still enigmatic. Its repercussions on the functional level can be disabling. Its clinical sides include atrophy and sclerosis. The evolution of the past towards great atrophies (kraurosis vulvae) may today be prevented by early diagnosis and treatment (essentially dermocorticoïde). Even if the risk of degenerescence is low, it's not negligible and these patients must be put under steady surveillance.
