Group A Streptococcal Vulvitis in Adult Women: Clinical Features and Association With Psoriasis.

OBJECTIVES: Group A streptococcus (GAS) vulvitis is rare, mainly reported in association with vaginitis. We examined the clinical features of GAS vulvitis in adults, the presence of other infected sites, and its association with dermatological conditions. MATERIALS AND METHODS: We retrospectively analyzed the medical files and photographs of adult patients with bacteriologically confirmed GAS vulvitis seen at 3 private clinics. Coexisting infected sites, associated dermatological conditions, and bacteriological results for the husbands of 3 patients were examined. RESULTS: Nineteen patients (mean age = 52.2 [range = 23-83] years) with vulvar GAS infections were identified. The vulvar symptoms consisted of pain (11 cases), pruritus (9), burning (4), and discharge (10). The predominant physical feature was bilateral erythema, mainly located on the labia minora and the inner aspect of the labia majora. This erythema was associated with oozing (3), edema (6), or fissures (6). Seventeen patients had an associated vaginal infection, which was asymptomatic in 7 cases; anal infections were present in 9 cases. The following 10 patients had associated dermatological conditions: psoriasis (6), lichen sclerosus (2), Paget disease (1), or vitiligo (1). Two (one each from the throat and penis) of the 3 bacteriological specimens taken from the 3 husbands were GAS positive. CONCLUSIONS: In most adult women, GAS vulvitis is associated with a vaginal infection that may be asymptomatic. A bilateral, oozing, and edematous or fissured erythema involving the vulvar or anovulvar area is suggestive of GAS vulvitis. The association with psoriasis and the benefits of screening household members and sexual partners deserves further attention.

Unilateral vulval swelling in cyclists: a report of 8 cases.

OBJECTIVE: To define the clinical features, imaging results, histopathologic patterns, and clinical outcomes seen in patients who develop vulval swelling as a result of intensive cycling. METHODS: The case notes of 8 female cyclists were retrospectively reviewed. RESULTS: The mean age of the patients was 45 years, and all were cycling long distances each week (range, 125-450 km; median, 210 km). All patients had a unilateral swelling of the labium majus. Five patients had magnetic resonance imaging showing asymmetry of the vulva with no enhanced signaling associated with inflammation. Histologic examination in 3 cases revealed dermal fibrosis and dermal edema associated with dilatation of lymphatic vessels. In 1 case, a perifollicular inflammatory infiltrate containing epithelioid granulomas was seen but Crohn's disease was excluded. In another case, fibromuscular hyperplasia was seen. Six patients had surgical excision of the swollen area, and 4 patients were able to resume cycling without problems up to 5 years of follow-up. The cosmetic appearance was initially considered satisfactory by 5 patients. However, 2 patients required a second surgical procedure to further improve the cosmetic appearance. In 1 case, there was a postoperative hematoma followed by an immediate recurrence of the swelling, which persisted. CONCLUSIONS: Unilateral swelling of the labium majus occurring in cyclists can be related to dermal fibroedema associated with lymphatic dilatation or to an increase in adipose tissue. Surgical results were satisfactory in 5 of the 6 patients who underwent excision.

Anti-HPV16 E2 protein T-cell responses and viral control in women with usual vulvar intraepithelial neoplasia and their healthy partners.

T-cell responses (proliferation, intracellular cytokine synthesis and IFNγ ELISPOT) against human papillomavirus 16 (HPV16) E2 peptides were tested during 18 months in a longitudinal study in eight women presenting with HPV16-related usual vulvar intraepithelial neoplasia (VIN) and their healthy male partners. In six women, anti-E2 proliferative responses and cytokine production (single IFNγ and/or dual IFNγ/IL2 and/or single IL2) by CD4+ T lymphocytes became detectable after treating and healing of the usual VIN. In the women presenting with persistent lesions despite therapy, no proliferation was observed. Anti-E2 proliferative responses were also observed with dual IFNγ/IL2 production by CD4+ T-cells in six male partners who did not exhibit any genital HPV-related diseases. Ex vivo IFNγ ELISPOT showed numerous effector T-cells producing IFNγ after stimulation by a dominant E2 peptide in all men and women. Since the E2 protein is absent from the viral particles but is required for viral DNA replication, these results suggest a recent infection with replicative HPV16 in male partners. The presence of polyfunctional anti-E2 T-cell responses in the blood of asymptomatic men unambiguously establishes HPV infection even without detectable lesions. These results, despite the small size of the studied group, provide an argument in favor of prophylactic HPV vaccination of young men in order to prevent HPV16 infection and viral transmission from men to women.

Spontaneous regression of grade 3 vulvar intraepithelial neoplasia associated with human papillomavirus-16-specific CD4(+) and CD8(+) T-cell responses.

Cell-mediated immunity directed against human papillomavirus 16 (HPV-16) antigens was studied in six patients affected with grade 3 vulvar intraepithelial neoplasia (VIN3, also known as bowenoid papulosis). Five of the patients presented with a chronic and persistent disease that relapsed after destructive treatments. They showed no detectable anti-HPV blood T-cell responses and no T-cell intraepidermal vulvar infiltrate containing both CD4+ and CD8+ lymphocytes. The last patient had a complete clearance of viral lesions, 8 months after disease onset and 2 months after electrocoagulation of <50% of the VIN3 lesions. She showed high frequency anti-E6 and anti-E7 effector blood T cells by ex vivo ELISpot-IFNgamma assay before clinical regression. Immunohistochemical study of her vulvar biopsy revealed a marked dermal infiltrate containing a majority of CD4+ T lymphocytes and an epidermal infiltrate made up of both CD4(+) and CD8(+) T cells. This seems to be the first evidence of an association between spontaneous regression of VIN3 lesions and HPV-specific T-cell responses detectable in the blood. Hence, an increase of HPV-specific effector T lymphocyte responses by vaccine-based therapeutic strategies might be useful to clear the lesions in bowenoid papulosis disease.
