Histopathologic patterns of female genital tuberculosis with clinical correlation: a 10-year (2013-2022) retrospective cross-sectional study.

OBJECTIVE: Underdiagnosis of female genital tuberculosis (FGTB) often leads to infertility. In this study, we aimed to determine the site and histopathologic patterns of FGTB and its correlation with clinical presentation and acid-fast bacilli (AFB) status. METHODS: A retrospective cross-sectional study was conducted on 122 patients with a histopathological diagnosis of FGTB at the Department of Pathology, College of Health Sciences (CHS), Tikur Anbessa Specialized Hospital (TASH), Addis Ababa University (AAU), from January 1, 2013, to August 30, 2022. RESULTS: Female genital tuberculosis was found in 0.94% of the gynecology specimens examined. The most common presentations were menstrual disturbance, abdominopelvic pain, and infertility. Among patients with FGTB, 4.6% exhibited misleading clinical and radiologic findings, leading to suspicion of malignancy and subsequent aggressive surgical management. The endometrium was the most frequently affected organ, followed by the fallopian tube, ovary, cervix, and vulva. In the majority of tuberculous endometritis cases (53.3%), histopathology revealed early-stage granulomas. Acid-fast bacilli were found in a significant proportion (42.6%) of FGTB tissues with TB histopathology. The ovary had the highest rate of AFB detection, followed by the fallopian tube, endometrium, and cervix. CONCLUSION: Female genital tuberculosis should be considered in reproductive-age women presenting with menstrual irregularities, abdominopelvic pain, infertility, or an abdominopelvic mass. The endometrium is commonly affected, displaying early granulomas with low AFB positivity.

Characterization of Bovine papillomavirus 28 (BPV28) and a novel genotype BPV29 associated with vulval papillomas in cattle.

Papillomavirus (PV) infections are associated with the development of cutaneous and mucosal tumors in humans and various animal species. In humans, infection of high-risk human PVs (HPVs) causes anogenital cancers, while in animals, anogenital-associated PVs are not well understood. Among animal PVs, Bos taurus PVs (BPVs) have the most diverse genotypes, up to 28 of them. The present study will report two unique BPVs identified in vulval papilloma lesions from two Holstein Friesian cattle by conventional PCR and sequencing. In the first case, BPV28 harboring two L1 open reading frames (ORFs) due to a five-nucleotide deletion was identified. In the second case, histologically diagnosed as papilloma, an unclassified BPV genotype was detected. However, in both cases, the immunohistochemistry against PV antigen was negative. The full genome of the unclassified BPV was amplified by inverse PCR and analyzed by genome-walking sequencing. The L1 nucleotide sequence was most identical to BPV genotype 6 (BPV6), showing 78 % identity, indicating that this novel BPV should be classified as species Xipapillomavirus 1, genotype BPV29. The mRNA expression of three early genes (E1, E2, E10), but not L1, was confirmed in both BPV28- and BPV29-detected papilloma lesions. The present study suggests the involvement of novel types of BPV in vulval papilloma. The alteration of BPV28 pathogenicity due to the frameshift mutation of L1 needs to be elucidated in the future.

Is Vulvovaginal Lichen Planus Associated With Squamous Cell Carcinoma?

OBJECTIVE: The aim of the study was to assess for the presence of vulvar lichen planus (LP) in association with human papillomavirus (HPV)-independent squamous cell carcinoma (SCC). MATERIALS AND METHODS: We performed a clinicohistopathologic review of consecutive vulvectomies and wide local excisions for HPV-independent vulvar or vaginal SCC from 2007 to 2017. Data collected included site of SCC, adjacent precursor lesions and dermatoses, dermatologic treatment, and outcome. RESULTS: There were 43 cases of primary HPV-independent vulvar SCC treated by excision, but no vaginal cancers. Eighteen women (42%) had a preoperative diagnosis of lichen sclerosus (LS); none had a diagnosis of LP. Topical corticosteroids were prescribed in 19 (44%) of 43, with 4 women placed on maintenance therapy. Tumors arose from the labia minora, labia majora, and periclitoris, but not from vestibule or perianus. On histopathological review, LS was present in 41 (95%) of 43 specimens, 1 had a nonspecific lichenoid reaction, and 1 had lichen simplex; both of the latter had subsequent biopsies showing LS. Lichen planus was not seen in association with SCC. Differentiated vulvar intraepithelial neoplasia (dVIN) was present in 38 (88%) of 43 specimens, whereas 1 had acanthosis with altered differentiation and 4 (9%) had no precursor lesion. Differentiated vulvar intraepithelial neoplasia had standard, basaloid, and hypertrophic morphology, superficially resembling erosive LP in 9 (24%) of 38 and hypertrophic LP in 6 (16%) of 38. CONCLUSIONS: Lichen planus was not seen in association with HPV-independent vulvar SCC, whereas LS was underrecognized and inadequately treated in this group. Pathologists should be aware that dVIN may superficially resemble erosive or hypertrophic LP.

Skin diseases of the vulva: Infectious diseases.

A multitude of infectious diseases of viral (genital herpes, herpes zoster, genital warts and molluscum contagiosum), bacterial (syphilis, chancroid, lymphogranuloma venereum, donovanosis, erysipelas, cellulitis and necrotising fasciitis, folliculitis, impetigo, bartholin gland abscess, trichomycosis and erythrasma), fungal (candidiasis and dermatophytosis) and parasitic (pediculosis pubis) origin may affect the vulvar area. Herein, we review the infections and their skin manifestations in the vulvar area.

Vulvar pseudoepitheliomatous hyperplasia associated with herpes simplex virus type II mimicking cancer in an immunocompromised patient.

We report an exaggerated dermatological inflammatory condition in an immunocompromised patient. The patient was a 51-year-old woman who had HIV infection and a history of cervical cancer. Three years after highly active antiretroviral therapy with an improved immune status, and 2 years after remission of cervical cancer, she developed verrucous perineal masses. Provisional diagnosis was recurrent cervical cancer or primary vulvar cancer. Pathological features revealed pseudoepitheliomatous hyperplasia associated with herpes viral infection. After minimal response to systemic oral antiviral drugs and topical imiquimod, she had clinical resolution with the addition of systemic oral corticosteroid.

Pseudomembranous colitis due to Clostridium difficile as a cause of perineal necrotising fasciitis.

Although rare, pseudomembranous colitis may be a cause of perineal necrotising fasciitis in a context of immunosuppression, as in the case we report. This origin must be quickly identified because the therapeutic management, especially surgery, is unlikely to be the same as usual. Similarly, antibiotic treatment is also a matter of discussion due to the potential deleterious role of antibiotics in pseudomembranous colitis.

Assessment of best single sample for finding chlamydia in women with and without symptoms: a diagnostic test study.

OBJECTIVE: To compare vulvovaginal swabs with endocervical swabs as optimal diagnostic sample for detection of Chlamydia trachomatis infection. DESIGN: A diagnostic test study. SETTING: An urban sexual health centre. PARTICIPANTS: 3973 women aged ≥ 16 years requesting testing for sexually transmitted infections. INTERVENTIONS: Participants took a vulvovaginal swab before routine examination, and clinicians took an endocervical swab during examination. MAIN OUTCOME MEASURE: Diagnosis of chlamydia infection with samples analysed using the Aptima Combo-2 assay; positive results confirmed with the Aptima CT assay. RESULTS: Of the 3973 participants, 410 (10.3%) were infected with C trachomatis. Infected women were significantly younger (22 v 25 years, P<0.0001) and more likely to have symptoms suggestive of a bacterial sexually transmitted infection (53% v 41%, odds ratio 1.63 (95% CI 1.30 to 2.04)), be a contact of someone with a sexually transmitted infection (25% v 5%, odds ratio 6.18 (4.61 to 8.30)), clinically diagnosed with cervicitis (17% v 4%, odds ratio 4.92 (3.50 to 6.91)), and have pelvic inflammatory disease (9% v 3%, odds ratio 2.85 (1.87 to 4.33)). When women co-infected with gonorrhoea were included in the analysis, there was an association with mixed ethnicity (10% v 7%, odds ratio 1.53 (1.07 to 2.17)); but when those with gonorrhoea were removed, women of white ethnicity were significantly more likely to have chlamydia (85% v 80%, odds ratio 1.40 (1.03 to 1.91)). On analysis of complete paired results, vulvovaginal swabs were significantly more sensitive than endocervical swabs (97% (95% CI 95% to 98%) v 88% (85% to 91%), P<0.00001); corresponding specificities were 99.9% and 100%. In women with symptoms suggestive of a bacterial sexually transmitted infection, vulvovaginal swabs were significantly more sensitive than endocervical swabs (97% (93% to 98%) v 88% (83% to 92%), P=0.0008), as they were in women without symptoms (97% (94% to 99%) v 89% (84% to 93%), P=0.002). CONCLUSIONS: Vulvovaginal swabs are significantly better than endocervical swabs at detecting chlamydia in women with and without symptoms suggestive of sexually transmitted infections. In those with symptoms, using endocervical samples rather than vulvovaginal swabs would have missed 9% of infections, or 1 in every 11 cases of chlamydia. TRIAL REGISTRATION: ISRCTN42867448.

Assessment of self taken swabs versus clinician taken swab cultures for diagnosing gonorrhoea in women: single centre, diagnostic accuracy study.

OBJECTIVE: To compare gonorrhoea detection by self taken vulvovaginal swabs (tested with nucleic acid amplification tests) with the culture of urethral and endocervical samples taken by clinicians. DESIGN: Prospective study of diagnostic accuracy. SETTING: 1 sexual health clinic in an urban setting (Leeds Centre for Sexual Health, United Kingdom), between March 2009 and January 2010. PARTICIPANTS: Women aged 16 years or older, attending the clinic for sexually transmitted infection (STI) testing and consenting to perform a vulvovaginal swab themselves before routine examination. During examination, clinicians took urethral and endocervical samples for culture and an endocervical swab for nucleic acid amplification testing. INTERVENTIONS: Urethra and endocervix samples were analysed by gonococcal culture. Vulvovaginal swabs and endocervical swabs were analysed by the Aptima Combo 2 (AC2) assay; positive results from this assay were confirmed with a second nucleic acid amplification test. MAIN OUTCOME MEASURES: Positive confirmation of gonorrhoea. RESULTS: Of 3859 women with complete data and test results, 96 (2.5%) were infected with gonorrhoea (overall test sensitivities: culture 81%, endocervical swabs with AC2 96%, vulvovaginal swabs with AC2 99%). The AC2 assays were more sensitive than culture (P<0.001), but the endocervical and vulvovaginal assays did not differ significantly (P=0.375). Specificity of all Aptima Combo 2 tests was 100%. Of 1625 women who had symptoms suggestive of a bacterial STI, 56 (3.4%) had gonorrhoea (culture 84%, endocervical AC2 100%, vulvovaginal AC2 100%). The AC2 assays were more sensitive than culture (P=0.004), and the endocervical and vulvovaginal assays were equivalent to each other. Of 2234 women who did not have symptoms suggesting a bacterial STI, 40 (1.8%) had gonorrhoea (culture 78%, endocervical AC2 90%, vulvovaginal AC2 98%). The vulvovaginal swab was more sensitive than culture (P=0.008), but there was no difference between the endocervical and vulvovaginal AC2 assays (P=0.375) or between the endocervical AC2 assay and culture (P=0.125). The endocervical swab assay performed less well in women without symptoms of a bacterial STI than in those with symptoms (90% v 100%, P=0.028), whereas the vulvovaginal swab assay performed similarly (98% v 100%, P=0.42). CONCLUSION: Self taken vulvovaginal swabs analysed by nucleic acid amplification tests are significantly more sensitive at detecting gonorrhoea than culture of clinician taken urethral and endocervical samples, and are equivalent to endocervical swabs analysed by nucleic acid amplification tests. Self taken vulvovaginal swabs are the sample of choice in women without symptoms and have the advantage of being non-invasive. In women who need a clinical examination, either a clinician taken or self taken vulvovaginal swab is recommended.

Recurrent vulvovaginal candidosis: focus on the vulva.

Recurrent vulvovaginal candidosis is a frequent disease with a serious impact on women's quality of life. Mostly, recurrences are caused by identical Candida strains suggesting C. albicans persistence in the female anogenital area. Objectives of the presented work were to identify the site of C. albicans persistence, to determine clinical symptoms and signs related to C. albicans positive vulvar cultures and to introduce a new therapeutic approach in women with RVVC. Women with an acute, culture-confirmed episode of RVVC at time of visit were included in this prospective case series. Swabs were obtained from both vagina and inter-labial sulcus. Women received a combined 20-day regimen of 100 mg oral fluconazole and ciclopiroxolamin cream topically. Follow-up visits were at 3, 6, 9 and 12 months. Of 139 women, 105 (76%) had at least one C. albicans positive culture from the external vulva. Vulvar positive cultures correlated with pruritus (OR 5.4; P < 0.001), vulvar edema (OR 3.8; P = 0.03) and fissures (OR 2.4; P = 0.03). Recurrence rates were 27%, 33% and 34% (at 6, 9, 12 months, respectively). The external vulva appears to represent a site of C. albicans persistence and source of endogenous re-infection in patients with RVVC. The combined treatment compared favorably with published fluconazole maintenance regimens.

National audit of asymptomatic screening in UK genitourinary medicine clinics: clinic policies audit.

Of clinics responding to the audit, 99 and 97% have policies that are compliant with the British Association for Sexual Health and HIV National Guidelines for testing of asymptomatic men and women for HIV and syphilis, respectively. All clinics offer men, and all but one clinic offer women, screening for chlamydial infection with nucleic acid amplification tests (NAATs), as recommended by the guidelines. However, for gonorrhoea screening one-third of clinics offer men urine or urethral NAATs, and one quarter of clinics offer women endocervical, vulvovaginal or urinary NAATs, and not endocervical culture, and these practices are not compliant with the guidelines. Eight clinics did not specify whether they routinely offer testing for gonorrhoea in women. One-third of clinics routinely perform rectal and oropharyngeal screening for gonorrhoea in men who have sex with men (MSM), but fewer screen for chlamydia, regardless of sexual history which is stated as a determinant of offering screening at these anatomical sites. Finally, one-fifth of clinics offer urethral microscopy to asymptomatic heterosexual men and MSM, and about one half of clinics offer urethral culture for detection of gonorrhoea in asymptomatic women, even though these practices are not compliant with the guidelines.

Combined actinomycotic and pseudoactinomycotic radiate granules in the female genital tract: description of a series of cases.

BACKGROUND: Both actinomycotic granules and pseudoactinomycotic radiate granules (PAMRAGs) occur in the female genital tract, most commonly in the endometrium. It is important to distinguish between these since the former may result in pelvic inflammatory disease and require antibiotic treatment while the latter is non-infectious and does not require specific treatment. AIMS: To investigate the coexistence of actinomyces-like organisms and PAMRAGs in the same granules, and describe the presence of PAMRAGs in the cervix and the vulva. METHODS: Six cases with actinomyces-like organisms and PAMRAGs in the same granules (four in the endometrium, one in a tubo-ovarian abscess, and one in both the endometrium and a tubo-ovarian abscess) are reported as well as seven examples of PAMRAGs in the cervix and one in a vulval abscess. RESULTS: The combined granules consisted of central basophilic Gram and silver positive filamentous organisms consistent with actinomyces surrounded by radiating eosinophilic club-like formations which were Gram and silver negative, the latter consistent with PAMRAGs. The PAMRAGs in the cervix and vulva consisted entirely of Gram and silver negative radiating eosinophilic club-like formations. CONCLUSIONS: Although actinomycotic granules and PAMRAGs are distinct lesions which should be distinguished for patient management, they may coexist in the same granules. It is likely in such cases that the PAMRAGs form around the bacterial colonies which act as a nidus. The presence of radiating eosinophilic club-like formations characteristic of PAMRAGs does not preclude the presence of actinomyces. Careful morphological examination plus supportive Gram and silver stains, if necessary, allows the diagnosis of these combined granules. PAMRAGs also occur in the cervix, where it is likely that they form secondary to encrustation of inspissated mucus, and in the vulva.

Malignant edema in postpartum dairy cattle.

Five cases of postparturient vulvovaginitis and metritis in cattle caused by Clostridium septicum (malignant edema) are described in the current report. The diagnosis was established based on detection of C. septicum by culture and fluorescent antibody test. All animals were Holsteins, and 4 were primiparous (the parity of 1 animal was not reported). All animals developed clinical signs 1-3 days after calving, consisting of swelling of perineal and perivulvar areas, fever, and depression. Perineal, perivulvar, and perivaginal gelatinous and often hemorrhagic edema was consistently observed on gross examination. Longitudinal vulvar, vaginal, cervical, and uterine body tears, covered by fibrinous exudates, were also present. Microscopically, vulvar, vaginal, and uterine mucosae were multifocally necrotic and ulcerated. Large Gram-positive rods, some with subterminal spores, were present within the edematous subcutaneous and submucosal tissues. Clostridium septicum was demonstrated by culture and/or fluorescent antibody test in tissues of most animals. These cases of malignant edema were considered to be produced by C. septicum and predisposed by the trauma occurring during parturition.

Mycoplasma genitalium in asymptomatic patients: implications for screening.

OBJECTIVES: Mycoplasma genitalium is well established as a cause of urethritis and has also been associated with cervicitis, endometritis and pelvic infection. Low rates of infection suggest screening may be inappropriate in the general population, but it remains unclear whether asymptomatic patients attending a sexual-health clinic should be tested routinely. The objective of this study was to measure the positivity rate of M genitalium infection in asymptomatic individuals presenting to a sexual-health clinic to inform the need for screening in this population. METHODS: Asymptomatic patients were identified using a structured questionnaire and tested for M genitalium from genital swabs or urine using two separate polymerase chain reaction (PCR) assays incorporating different primer sequences. RESULTS: 1304 patients were approached over a 6-month period. 743 (57%) patients were symptomatic, and 168 (13%) refused consent, leaving 394 (30%) patients who entered the study. Residual samples were available for 308 (79%) patients, 168 (54%) men and 140 (46%) women. 14/308 (4.5%, 95% CI 2.2 to 6.9%) asymptomatic patients were infected with M genitalium, and an additional 2 (0.6%, 95% CI 0.2 to 2.3%) patients had discrepant PCR results. No significant associations were found between M genitalium infection and age, gender, ethnicity or isolation site. CONCLUSION: The positivity rate of M genitalium infection in asymptomatic sexual-health clinic attendees is comparable with that of gonorrhoea or chlamydia, and, if evidence of pathogenicity continues to accumulate, a further assessment of the role of routine screening in this setting would be appropriate.

Tubercular sinus of labia majora: rare case report.

Tuberculosis of the female external genitalia is unusual and primary infection is rare. We report a 50-year-old female patient admitted to Department to Surgery with swelling over left inguinal area with discharging sinus from labia majora to left inguinal crease which was found to be tubercular sinus on histopathology.

Clinical aspects and luteal phase assessment in patients with recurrent vulvovaginal candidiasis.

OBJECTIVE: This study was undertaken to characterize the patients with recurrent vulvovaginal candidiasis. STUDY DESIGN: Basic data of personal history and history of recurrent vulvovaginal candidiasis, lower genital tract symptoms and signs in 50 patients were analyzed in this longitudinal follow-up study including the determination of midluteal serum progesterone and urinary pregnanediol levels during the luteal phase in 84 cycles (recurrent vulvovaginal candidiasis) and 60 cycles (healthy controls). RESULTS: All patients suffered primary idiopathic form of recurrent vulvovaginal candidiasis. Frequently, there was a striking discrepancy between severe symptoms and clinical finding, which was often negligible or normal. There was no redness and no or minimum discharge in 52% of culture documented attacks. In contrast to the healthy controls, the patients had significantly lower levels of progesterone (p<0.01) as well as those of urinary pregnanediol (p<0.05). CONCLUSION: Culture positive attacks in patients with recurrent vulvovaginal candidiasis represented rather a form of vulvovaginal discomfort than attacks of vulvovaginal candidiasis with typical inflammatory changes. Significantly lower progesterone levels in the RVVC patients as compared to the healthy controls suggest a link between an altered hormonal status and one of possible causes of RVVC in these women.

Vulvovaginal-swab or first-catch urine specimen to detect Chlamydia trachomatis in women in a community setting?

Screening for chlamydia in women is widely recommended. We evaluated the performance of two nucleic acid amplification tests for detecting Chlamydia trachomatis in self-collected vulvovaginal-swab and first-catch urine specimens from women in a community setting and a strategy for optimizing the sensitivity of an amplified enzyme immunoassay on vulvovaginal-swab specimens. We tested 2,745 paired vulvovaginal-swab and urine specimens by PCR (Roche Cobas) or strand displacement amplification (SDA; Becton Dickinson). There were 146 women infected with chlamydia. The assays detected 97.3% (95% confidence interval [CI], 93.1 to 99.2%) of infected patients with vulvovaginal-swab specimens and 91.8% (86.1 to 95.7%) with urine specimens. We tested 2,749 vulvovaginal-swab specimens with both a nucleic acid amplification test and a polymer conjugate-enhanced enzyme immunoassay with negative-gray-zone testing. The relative sensitivities obtained after retesting specimens in the negative gray zone were 74.3% (95% CI, 62.8 to 83.8%) with PCR and 58.3% (95% CI, 46.1 to 69.8%) with SDA. In community settings, both vulvovaginal-swab and first-catch urine specimens from women are suitable substrates for nucleic acid amplification tests, but enzyme immunoassays, even after negative-gray-zone testing, should not be used in screening programs.
