A Mimicker of Differentiated Vulvar Intraepithelial Neoplasia: Reactive Atypia From Noncompliance With Lichen Sclerosus Therapy.

ABSTRACT: Differentiated vulvar intraepithelial neoplasia (d-VIN) is an HPV-independent precursor to vulvar squamous cell carcinoma. The histology of d-VIN lesions is difficult to differentiate from that of non-neoplastic epithelial disorders, especially lichen sclerosus (LS). The authors present a case of LS, where relying on histopathology alone could have led to misdiagnosis. The patient was a 17-year-old female patient with clinical features of vulvar dermatitis and LS for 2 years. She was counseled to apply clobetasol 0.05% to the affected area daily but reported no improvement after 6 months. A biopsy of the right labia majora revealed histologic findings typical of d-VIN and near-contiguous p53 expression. These features are characteristic of d-VIN. However, d-VIN is exceedingly rare in young patients. The case was reviewed by 6 dermatopathologists and gynecologic pathologists, who observed that the degree of inflammation would be unusual postclobetasol therapy and could be due to noncompliance. A review of the patient's chart revealed that she "does not always remember to apply" clobetasol. The patient's clinician confirmed that there were compliance issues, and the follow-up biopsy was negative for d-VIN. The case was signed out as LS, with a note describing the above, and to rebiopsy if concern persisted. The authors conjecture that inflammatory infiltrates in the biopsied area caused reactive atypia due to lack of adherence to treatment. Although the patient's age helped rule out d-VIN, similar cases in elderly patients may be occurring. Pathologists must be aware that reactive forms of untreated LS can mimic d-VIN, to avoid misdiagnosis.

Interest in and uptake of genetic counseling for preconception carrier screening when offered to predominantly white reproductive-age persons seeking gynecologic care at a single U.S. academic medical center.

The objective of this study was to assess the level of interest in preconception carrier screening among reproductive-aged persons presenting for gynecologic care and to identify demographic factors predictive of pursuing screening. Patients aged 18-40 who were presenting for gynecologic care at a single U.S. academic medical center were provided with information about current options for preconception carrier screening and were offered genetic counseling referral with the possibility to undergo screening. Outcomes of interest were desire for genetic counseling referral and attendance at genetic counseling visit. Statistical analyses were performed as appropriate using R version 3.6.1 with variables significant at 0.1 included in a multivariable logistic regression. Of 193 participants, 79 (41%) desired genetic counseling referral. Participants aged 25-34 (OR 3.39, 95% CI 1.47-8.10) and nulliparas (OR 2.69, 95% CI 1.23-6.03) were more likely to desire referral. Thirty-five participants (44.3% of those who desired referral) attended a visit with genetic counseling. Having an advanced degree (OR 3.27, 95% CI 1.06-10.4) was associated with visit attendance. Thirteen participants underwent screening, and five were found to be a carrier of at least one X-linked or autosomal recessive condition. Surprisingly, presenting for a gynecologic visit directly related to planning a pregnancy was not associated with increased interest in preconception carrier screening. Nulliparas and those aged 25-34 likely expressed greater interest in referral due to high potential for future childbearing in these groups. The increased level of visit attendance in participants with advanced degrees is likely confounded by the high level of health literacy and financial resources in this group.

Prophylactic Negative Pressure Wound Therapy and Wound Complication After Cesarean Delivery in Women With Class II or III Obesity: A Randomized Controlled Trial.

OBJECTIVE: To compare the occurrence of superficial surgical site infections in obese women using prophylactic negative pressure therapy with standard dressings after cesarean delivery. METHODS: We conducted a randomized controlled, nonblinded, two-center study of prophylactic negative pressure therapy compared with standard surgical dressings placed at the time of primary closure at cesarean delivery in obese women with body mass indexes (BMI) of 35 or higher (ie, class II and III obesity). Our primary outcome was occurrence of a superficial surgical site infection. We assumed a superficial surgical site infection occurrence rate of 20% and intended to recruit 400 women. However, after low enrollment of 166 women over 24 months, an interim analysis for futility was conducted and the decision was made to halt the study. RESULTS: Women were recruited between January 5, 2015, and January 7, 2017, from two sites. The mean BMI on admission was 44.9 (±8) for the prophylactic negative wound therapy group and 43.4 (±7) for the standard dressing group. There were no differences in the occurrence of observed superficial surgical site infections between women using prophylactic negative pressure wound therapy (12/80 [15%]) compared with women who received the standard dressing (8/81 [10%], P=.35, relative risk 1.52, 95% CI 0.66-3.52). There were no differences in the occurrence of composite wound complications between women using prophylactic negative pressure wound therapy (25/80 [31%]) compared with women who received the standard dressing (24/81 [30%], P=.87). CONCLUSION: In this randomized controlled trial that did not achieve full anticipated enrollment, we did not observe a decrease in superficial surgical site infections after cesarean delivery in obese women with the use of prophylactic negative pressure wound therapy.
