Abstract
Genital involvement is a rare manifestation in discoid lupus erythematosus (DLE) and systemic lupus erythematosus (SLE), and there are few reports on vulvar clinical features. We describe a 41-year old Caucasian woman with bilateral vulvar DLE. Although vulvar lesions in lupus are probably more common than is realized, the present report is the first case of genital DLE documented in a female.

Abstract
Vulvovaginal-gingival lichen planus (VVG-LP) consists of a triad of symptoms: vulval, vaginal and gingival lichen planus lesions. The aim of this study was to analyse the prevalence of lesions in various anatomical locations in patients with VVG-LP. The study included 126 consecutive patients with lichen planus. Sixteen (12.7%) patients fulfilled the criteria of VVG-LP. In 12/16 (75%) patients with VVG-LP scalp lesions were also observed. Stratified epithelium-specific antinuclear antibodies (SES-ANA) and anti-ΔNp.3α antibodies were detected in 10/16 (75%) patients with VVG-LP and in 15/110 (13.6%) patients with other forms of lichen planus (p < 0.05). In conclusion, VVG-LP is frequently associated with lichen planopilaris. The new entity may be termed "vulvovaginal-gingival-pilar lichen planus" and our study indicates that SES-ANA is a marker of this type of lichen planus with extensive, severe and refractory-to-therapy involvement of the mucous membranes, skin and scalp.

Abstract
A study of the HLA-A, B and DR antigens and properdin factor B allotypes of 26 patients with lichen sclerosus et atrophicus and a normal control population showed an increase in the HLA-Aw31 antigen only. However, when the HLA-A and B frequencies were combined with the results of a previous independent study a significant increase in both HLA-Aw31 and HLA-B40 was noted. These findings suggest an association between lichen sclerosus et atrophicus and the HLA system.

Abstract
Anti-tumour necrosis factor-alpha therapy of Crohn's disease (CD) with infliximab has proved a major advance in the treatment of patients with difficult disease. We report our experience of the use of infliximab in a patient with recalcitrant vulval CD. The introduction of infliximab has improved disease control, although a search for an optimum remittive dosing schedule is ongoing.

The vulvovaginal gingival syndrome: A severe subgroup of lichen planus with characteristic clinical features and a novel association with the class II HLA DQB1∗0201 allele. J Am Acad Dermatol 2006; 55:98-113. [PMID: 16781300 DOI: 10.1016/j.jaad.2005.12.006] [Citation(s) in RCA: 77] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2004] [Revised: 11/30/2005] [Accepted: 12/04/2005] [Indexed: 11/21/2022]
Abstract
BACKGROUND The vulvovaginal gingival syndrome is an uncommon and severe variant of lichen planus characterized by erosions or desquamation of vulval, vaginal, and gingival mucosae with a predilection for scarring and stricture formation. OBJECTIVE We sought to define the clinical, immunopathologic, and human leukocyte antigen findings in a large cohort of patients. METHODS The clinical presentation and outcome during long-term follow-up were documented in 40 patients. In addition, human leukocyte antigen typing for class II by polymerase chain reaction and sequence-specific primers was performed. RESULTS During a mean follow-up period of 8.7 (SD +/- 6.8) years, long-term sequelae included strictures of the esophagus, lachrymal ducts, and external auditory canal; loss of vulval architecture; vaginal stenosis; and buccal mucosal fibrosis. The DQB1( *)0201 allele was present in 80% of patients versus 41.8% of control subjects (P <or= .0042; relative risk 3.71). CONCLUSION Early diagnosis of this distinct subgroup of lichen planus, combined with appropriate therapeutic measures, may help to minimize the significant physical and psychologic morbidity associated with this scarring disorder.

Abstract
We have observed that the majority of our vulvodynia patients give a previous history of vaginal candidiasis that was treated but was followed by symptoms of chronic vulvodynia. 27 vulvodynia patients were patch-tested to a standard series of contact allergens, a customized vulvar series and commensal organisms including ultraviolet-killed Candida albicans. Comparison tests for the commensal organism were made to a group of 13 female atopic dermatitis patients and to 19 female dermatitis patients without a history of childhood flexural dermatitis who were undergoing patch test evaluation in our clinic. Patients reporting vulvodynia were significantly (P < 0.05) more likely to react to C. albicans than the dermatitis comparison group. Interestingly, lower concentrations of C. albicans caused more positive patch tests than higher concentrations. Our findings suggest that previous C. albicans infection may predispose patients to a subsequent hypersensitivity response to C. albicans that is expressed only in areas of high cutaneous peripheral fibre density. Low levels of C. albicans may also be required to elicit this response as high levels of C. albicans may actually result in decreased cutaneous inflammation and decreased intensity of C. albicans patch test responses.

Lack of specific immunological disease pattern in vulvar lichen sclerosus. Exp Mol Pathol 2005; 79:176-85.

Abstract
The literature suggests that autoantibody formations and disturbances in cellular or humoral immunities are relevant immunological events in lichen sclerosus (LS). We examined 39 patients (age range: 7-81 years) enrolled in this experimental immunopathology study and treated for vulvar LS. In the serum, we used 88 clinical immunology parameters to evaluate the immunological patterns, i.e., autoimmune phenomena, humoral immunity, cellular immunity, and inflammation. The analyses permitted direct comparison of the measured distributions of alternative data. We found that all pathological findings of single immunological events followed a random distribution without any positive or negative trend or a distribution with a negative trend. There was a lack of correlation between the majority of cases and the presence of pathological findings (confidence intervals 0.950 and 0.999). Combinations of two or more of the four patterns did not improve the outcomes (confidence intervals 0.950 and 0.999). However, abnormalities in systemic immune parameters implying system impairments might have occurred long before the patients with such a chronic disease presented to the clinic. This may be especially true of such diseases as vulvar LS, where local skin scarring might represent a local tissue response secondary to an initial insult by immune or other processes.

Abstract
The objective of this study was to investigate whether circulating basement membrane zone (BMZ) antibodies are present in erosive lichen planus (LP) of the vulva. In total, 56 consecutive women with biopsy-confirmed erosive LP of the vulva were recruited from a vulval clinic in a district general hospital and teaching hospital in Oxfordshire. Indirect immunofluorescence (IgG and IgA) was performed on 56 sera, and 15 were tested to IgG subclasses (1-4). Immunoblotting was carried out on salt-split and urea-extracted epidermal skin extracts on 11. The main outcome measure was the presence or absence of staining at the BMZ. Of the 56 sera, 34 (61%) had weak (neat or 1 : 5) epidermal-binding BMZ antibodies (25 had IgG, 5 had IgA, 4 had both IgG and IgA). All 15 sera tested to IgG showed epidermal binding to one or more IgG subclasses: IgG1 (7 sera), IgG2 (7), IgG3 (7) and IgG4 (0). Immunoblotting identified IgG antibodies to bullous pemphigoid (BP)180 (10/11) and BP230 (2/11). The majority (61%) of patients with vulval erosive LP had circulating serum IgG BMZ antibodies, chiefly reacting with BP180. There was subclass restriction of the IgG response to IgG1, 2 and 3. The significance of these antibodies is uncertain, but they may be a marker for the disease.

Abstract
Vulvar tissue differs from cutaneous epithelia in structure, morphology and biophysical characteristics. For example, the skin of the labia majora exhibits elevated hydration, occlusion and frictional properties, which may increase susceptibility to irritants and contact sensitizers. Furthermore, the nonkeratinized vulvar vestibule is likely to be more permeable than keratinized regions. These differences heighten vulvar susceptibility to topical agents. This reviews the structure and properties of vulvar tissue, emphasizing their impact on susceptibility contact irritants and allergens.

Abstract
Histopathology demonstrates disruption of the basal layer of the epidermis in lichen planus (LP) and altered expression of basement membrane zone (BMZ) components occurs in cutaneous and oral LP. This is the first study in erosive LP of the vulva to investigate the expression of components of the BMZ and extracellular matrix by indirect immunofluorescence. Six biopsies from lesional vulval erosive LP were compared with two biopsies from normal vulva and five biopsies from normal skin. In erosive vulval LP there was widespread disruption of several BMZ components compared to normal skin. The hemidesmosome antigens were disrupted and attenuated, or absent. Expression of lamina lucida proteins and anchoring filaments also showed some alteration. Lamina densa components were altered and in particular there was very marked thickening, streaking and fragmentation of the anchoring fibrils. Some dermal extracellular matrix proteins were increased. This study has demonstrated widespread damage to the BMZ in erosive LP of the vulva, in particular the hemidesmosomes (alpha6beta4 integrin, BP230, BP180) and anchoring fibrils (collagen VII). This suggests an alteration in antigenic expression in the BMZ that may lead to exposure of epitopes and thus make these proteins vulnerable to attack by autoantibodies.

Abstract
OBJECTIVE To determine the role of contact sensitization in vulvar lichen simplex chronicus and to select appropriate batteries of allergens to test. STUDY DESIGN Between 1993 and 2000, 61 women affected by vulvar lichen simplex chronicus were enrolled to evaluate the role of contact hypersensitivity. All the patients underwent patch tests with the Italian standard series and with a wide battery of allergens (preservatives, perfumes, emulsifiers, medicaments) and products they used routinely. RESULTS Of the women, 47.5% had at least one positive patch test, and relevant positivities were observed in 26%. The relevant allergens were usually medicaments and preservatives. CONCLUSION It would be acceptable to reduce the number of allergens tested, in particular omitting the perfume series. Patch tests are a helpful diagnostic tool in vulvar lichen simplex chronicus and improve prescribing practice.

Abstract
BACKGROUND Information about vulvovaginal and perianal condylomata acuminata and intraepithelial neoplasia in women infected with HIV-1 is needed to develop guidelines for clinical care. Our aim was to investigate the incidence of these lesions in HIV-1-positive and HIV-1-negative women and to examine risk factors for disease. METHODS In a prospective cohort study, 925 women had a gynaecological examination twice yearly-including colposcopy and tests for human papillomavirus DNA in cervicovaginal lavage-for a median follow-up of 3.2 years (IQR 0.98-4.87). FINDINGS Vulvovaginal and perianal condylomata acuminata or intraepithelial neoplasia were present in 30 (6%) of 481 HIV-1-positive and four (1%) of 437 HIV-1-negative women (p<0.0001) at enrollment. Women without lesions at enrollment were included in an incidence analysis. 33 (9%) of 385 HIV-1-positive and two (1%) of 341 HIV-1-negative women developed vulvovaginal or perianal lesions, resulting in an incidence of 2.6 and 0.16 cases per 100 person-years, respectively (relative risk 16, 95% CI 12.9-20.5; p < 0.0001). Risk factors for incident lesions included HIV-1 infection (p = 0.013), human papillomavirus infection (p=0.0013), lower CD4 T lymphocyte count (p = 0.0395), and history of frequent injection of drugs (p=0.0199). INTERPRETATION Our results suggest that HIV-1-positive women are at increased risk of development of invasive vulvar carcinoma. Thus, we recommend that, as part of every gynaecological examination, HIV-1-positive women should have a thorough inspection of the vulva and perianal region, and women with abnormalities-except for typical, exophytic condylomata acuminata-should undergo colposcopy and biopsy.

Abstract
Although patients with both morphoea and lichen sclerosus have been reported previously, in the majority of these reports the lichen sclerosus has been extragenital. We report nine patients in whom genital lichen sclerosus coexisted with scleroderma spectrum disorders including seven with morphoea, one with morphoea and lichen planus, and one with systemic sclerosis. The clinical features, associated autoimmune disease, autoantibodies and HLA type are reported. Antibodies to Borrelia burgdorferi were not detected in any of the patients. The coexistence of these diseases raises a number of intriguing questions about the relationship between them.

Abstract
Lichen sclerosus is among the most frequently seen paediatric vulval disorders. In adults a strong association between lichen sclerosus and autoimmune diseases, and also with HLA class II locus DQ7, has been well demonstrated in women and a weaker association in men. These associations have not previously been studied in children, although in other autoimmune diseases, the HLA associations have been strongest in children. We performed HLA tissue typing and looked for autoimmune associations in a group of 30 children with vulval lichen sclerosus. HLA DQ7 was present in 66% of female children with lichen sclerosus compared with 31% in controls. Previous studies reported DQ7 in 51% of adult female patients and 45% of male patients. Sixteen per cent of the children were homozygous for DQ7 as opposed to 5% of controls. In the childhood group, only 4% had another autoimmune disease, but 56% of their parents or grandparents did. Age differences make comparison difficult, but the family history of autoimmunity appears to be strong in the early-onset group, in addition to the stronger association with DQ7.

Abstract
To characterize the immunophenotype of inflammatory cells in lichen sclerosus (LS), we performed a comparative case control study using one- and two-color immunohistochemistry and the nitro blue tetrazolium (NBT) reaction. Study material consisted of 100 biopsies from patients with LS or from 12 control groups consisting of inflammatory, scarring, and depigmenting cutaneous disorders. In addition, fresh tissue was sampled from four vulvectomy specimens for NBT testing. The typical inflammatory infiltrate of LS contained numerous epidermotropic CD3+, CD8+, CD57+ cells, increased intraepidermal HLA-DR+ cells, and a dermal infiltrate rich in CD8+, CD57+, HLA-DR+, and CD68+ inflammatory cells. Comparing LS to the 12 control groups, epidermotropic CD57+ lymphocytes independently predicted LS (P = 0.006, logistic regression, multivariate analysis). Among the 12 control groups, only specimens of the inflammatory stage of morphea exhibited numerous dermal CD57+ lymphocytes. Two-color immunohistochemistry confirmed the CD3+/CD8+CD57+ and CD3+/ CD8+/CD57+HLA-DR+ epidermotropic and dermal lymphocytic phenotypes and the dermal macrophage CD68+HLA-DR+ phenotype. In LS, the NBT reaction revealed evidence of superoxide production associated with CD68+HLA-DR+ cells. Expansion of CD8+CD57+lymphocytes is associated with viral infections, autoimmune disease, malignancies, and transplantation and is suspected to be the result of chronic excessive antigen challenge. In these pathologic states, CD8+CD57+ lymphocytes (as terminally differentiated, antigen-specific T cells) participate in the suppression of cytolytic activity to limit tissue damage. In LS, activated macrophages and lymphocytes indicate persistent antigen-driven inflammation. LS's numerous CD8+CD57+ lymphocytes may be either the mediators or the consequence of its hallmark sclerosis.

Abstract
OBJECTIVE To investigate the seroimmunologic (CD3, CD4, CD8 lymphocytes, C3c and C4 complement fractions, and several autoantibodies) and immunohistochemical (T lymphocyte subpopulations, B lymphocytes, natural killer cells, macrophages, immunoglobulin [Ig] G, Ig M, and C3c complement fraction) characteristics of vulvar lichen sclerosus. METHODS Serum samples from 68 women with histologically proven lichen sclerosus were compared with those from 53 healthy controls, and tissue samples from 14 of 68 women chosen at random were compared with those from 14 of 53 healthy controls. A scoring system was constructed to compare the number of cells in the tissue. RESULTS Patients had significantly lower counts of circulating lymphocytes CD3 and CD4 than controls (P < .05) and a higher number of autoantibodies (P < .01). Analysis of the tissue samples confirmed a lower number of CD2 cells (two-tailed P = .002 in epidermis, .005 in dermis), CD3 cells (two-tailed P = .001 in epidermis and in dermis), CD4 cells (two-tailed P = .002 in epidermis, .011 in dermis), and CD8 cells (two-tailed P = .002 in epidermis, .051 in dermis) in subjects than in controls. Numbers of monocyte-macrophage cells were similar in the epidermis but different in the dermis (two-tailed P = .003). No natural killer CD56 cells or B lymphocytes (CD19-CD21) were detected in the affected areas. Deposits of IgG, IgM, and C3 were no greater in biopsy specimens of patients than in those of controls. CONCLUSION Vulvar lichen sclerosus is not caused by a T cell-mediated response, and a viral origin is unlikely. The absence of CD19 and CD21 cells excludes local production of autoantibodies. Our data do not confirm an autoimmune pathogenesis for vulvar lichen sclerosus but help explain why systemic cortisone is of no benefit and justify the use of petroleum jelly to relieve pruritus.

Abstract
The Buschke-Loewenstein tumor, also called giant condyloma acuminatum, is generally observed in male subjects, usually on the penis and rarely occurs in women. A case of Buschke-Loewenstein tumor located on the vulva is reported. It is a cauliflower-like tumor which behaves clinically in a malignant fashion, although it shows no histomorphological criteria of malignancy. Histologically it is a benign papillomatous growth characterized predominantly by epithelial hyperplasia, hyperacanthosis and hyperkeratosis. The assessment of humoral and cellular immunity demonstrated an unusual circulating increase of CD4+ lymphocytes suggesting their major role in the very slow progression of the disease. Surgery remains the treatment of choice for this tumor.

Abstract
An immunohistochemical approach was used to characterize the inflammatory infiltrate in vulval lichen sclerosus, using monoclonal antibodies to CD3, CD4, CD8, CD68 and HLA-DR. Significant numbers of CD4 + and CD8 + lymphocytes were observed in the dermal band of inflammatory cells in approximately equal proportions. Less numerous CD4 + and CD8 + lymphocytes also occurred adjacent to the dermoepidermal junction and occasionally in the lower epidermis. Increased numbers of cells staining with the monocyte/macrophage marker CD68 were also present in the band of inflammatory cells as well as being scattered diffusely throughout the sclerotic region. Expression of HLA-DR in the lichen sclerosus specimens was increased within the inflammatory infiltrate and around blood vessels in the dermis. All the vulval lichen sclerosus specimens also demonstrated some HLA-DR expression around the keratinocytes, suggesting that these keratinocytes might be involved in antigen presentation. We also studied the expression of CD44 and its isoforms 3G5 (marker of V3), 8G5 (marker of V6), 3D2 (marker of V4/5) and IE8 (marker of V8/9). CD44 has been proposed to play a part in lymphocyte homing, cell-matrix interaction (particularly with hyaluronic acid), lymphocyte activation and malignant progression of certain tumours. The epidermis of the lichen sclerosus specimens appeared to demonstrate a greater intensity of staining with the pan-CD44 marker F10-44, and reduced staining with 3G5, 3D2 and IE8 compared with normal skin. Like normal skin, the dermis of the lichen sclerosus specimens did not demonstrate staining with 3G5, 3D2, 8G5 or 1E8, but did show staining with F10-44. However, the pattern of the dermal staining with F10-44 reflected the position of the inflammatory infiltrate and was sparse in the five sections where there was a prominent sclerotic zone, but increased in the three sections where there was a prominent band of inflammation cells. Our results demonstrate evidence of immunological changes at all levels of skin involved by lichen sclerosus, including the epidermis.

Abstract
We describe five girls with vulval pemphigoid: two had bullous pemphigoid confined to the vulva and three had cicatricial pemphigoid. They demonstrate a spectrum of severity from localized disease to extensive vulval scarring necessitating long-term immunosuppressive therapy and surgical correction. The age at onset of their disease ranged between 6 and 13 years. All presented with vulval discomfort and erosions. Three had oral lesions, two perianal and one eye and cutaneous involvement. Two girls with only vulval lesions and one with vulval and oral lesions responded well to topical steroids. In two, systemic treatment with prednisolone and dapsone or azathioprine was required. The diagnosis was made on the basis of histology and immunofluorescence (IF). All had positive direct IF with IgG and C3. Indirect IF demonstrated circulating IgG binding to the basement membrane zone in four, with dermal or epidermal binding on salt-split skin substrate. Immunoblotting revealed antibodies to the BP230 and BP180 antigens. Immunoelectron microscopy in the child with dermal binding IgG and BP180 and BP230 on immunoblotting showed labelling at the lamina densa-lamina lucida interface adjacent to hemidesmosomes.

Abstract
Vulvar vestibulitis, a subset of vulvodynia, is present in 15% of patients in a general gynecologic practice. Only a few studies have focused on pathologic features of vulvar vestibulitis and none have included a control group. Punch biopsies from the vulvar vestibule of 12 patients with an age range of 22 to 51 years (mean 28 years) and 12 age-matched controls were analyzed for histopathologic features and investigated for the role of probable etiologic factors including human papillomavirus (HPV). A chronic inflammatory infiltrate was present in all specimens from patients with vestibulitis, and was composed predominantly of T-lymphocytes with a small number of B cells and an admixture of plasma cells, mast cells, and occasional monocytes. T-helper suppressor ratio was normal. The infiltrate was mild in 5 patients, moderate in 1, and severe in 6. Minor vestibular glands were observed in 8 (66%) patients and were associated with a periglandular inflammatory infiltrate. Squamous metaplasia was observed in 4 (44%) patients. Epithelial hyperplasia was present in 10 (83%) patients with mild dysplasia in 2 (16%). Immunohistochemistry for immunoglobulins IgG, IgA, and IgM showed the presence of IgG-positive plasma cells in 75% of patients, suggesting chronic irritation, but an autoimmune etiology cannot be excluded or confirmed. Biopsies of control cases did not show any inflammatory infiltrate. In situ hybridization for HPV 6, 11, 16, and 18 was negative in the patient group as well as in the control group. We conclude that histopathologic abnormalities in patients with vulvar vestibulitis are the result of a chronic inflammatory reaction of the mucosa of the vulvar vestibule, for which the cause remains unclear.

All phases of HPV infection are under the control of the immunitary system which is probably inhibited by the virus itself. We studied 65 patients (range 22-55 year). They presented an HPV vulvovaginal infection not healed after common therapy. The aim of our study was to verify the changes occurring in the immune system during HPV vulvo-vaginal infection. Using the immunohistochemical method we evaluated the number of T4,T8 and NK lymphocytes inside the lesion. Moreover we measured the immunitary cells of the hematic compartment. Inside the lesion we noted a reduction of the immune system in 69.23% of cases, while in the hematic compartment it was reduced only in 6.15% of cases. These data strongly suggested that the evaluation of the immunitary state, before starting therapy, is important in deciding when it would be useful to associate immunostimulating substances at the common treatment of vulvo-vaginal infection.

Abstract
In 20 women with vulvar lichen sclerosus (LS) we analyzed the immunohistologic features of the dermal lymphoid infiltrate and the number of epidermal CD1a+ cells (Langerhans cells). Activated (HLA-Dr+) T cells, associated with CD1a+ accessory cells, were found in the dermis in all cases. The number of CD1a+ epidermal cells was increased, and the cells expressed strong HLA-DR+ staining. These findings suggest activation of the skin immune system in vulvar LS lesions. Conventional 2% testosterone therapy failed to modify the immunohistologic features. Clobetasol, 0.05%, application seemed more effective in down-regulating the skin's immune system activation profile.

Abstract
The case is reported of a young atopic woman with combined Type I and possible Type IV allergy to human seminal plasma, as well as Type-I allergy to latex. Clinical symptoms were swelling and a burning sensation on the vulva and in the vulvovaginal area during or after coitus, followed by vesiculation, lichenification and the development of generalized eczema. Diagnosis was confirmed by investigation (RAST, prick testing, histology). Literature on the subject is reviewed.

Abstract
Cryostat sections of 20 clinical condylomata of the vulva induced by human papillomavirus and 5 normal control biopsies were examined using immunohistochemistry. The results indicated that in vulvar papillomavirus infection the intraepithelial Langerhans' cells showed abnormal morphology and a significantly lower density than controls. CD1a positive Langerhans' cells were also observed in dermis of condylomata, suggesting an abnormal epithelial traffic of dendritic cells. T lymphocytes with a mean CD4/CD8 ratio of 0.25 and a mean density of 267 +/- 59 cells/mm2 of epithelial section were the main cellular infiltrate in vulvar papillomavirus infection. Most of the T cells were HLA-DR negative. Those condylomata with moderate to severe mononuclear infiltrate showed leucocyte function antigen 1 positive T cells forming small clusters in the lower epithelial half around the ICAM-1 positive keratinocytes. Vulvar warts also showed epithelial areas with overlapped ICAM-1 and HLA-DR expression. Scattered T gamma-delta and B lymphocytes, macrophages and NK cells were observed among the cells of the dermal infiltrate of vulvar condylomata.

Abstract
BACKGROUND Childhood localized vulvar pemphigoid has been recently reported in four girls. A fifth child with this proposed rare variant of bullous pemphigoid is described. Moreover, findings in the various immunopathologic studies we performed establish this entity as a true morphologic variant of bullous pemphigoid. OBSERVATIONS In situ deposits of IgG in this patient's epidermal basement membrane zone localized to the epidermal side of 1 mol/L of saline-split skin. Moreover, the patient had circulating IgG autoantibodies that bound the epidermal side of 1 mol/L of saline-split skin in indirect immunofluorescence microscopy and immunoprecipitated the 230-kd bullous pemphigoid antigen from biosynthetically radiolabeled human keratinocyte extracts. These laboratory findings are identical to those documented in patients with the generalized "classic" form of bullous pemphigoid. CONCLUSIONS This study demonstrates that a child with clinical, histopathologic, and immunopathologic features of localized vulvar pemphigoid had circulating autoantibodies that identify a specific keratinocyte antigen, the bullous pemphigoid antigen, which may serve as a molecular marker for this disease.

Abstract
Cellular immunity was studied in 73 patients with recurrent vaginal moniliasis and 37 healthy controls, by skin testing with the multitest CMI kit and Candida antigen, with measurement of lymphoblastic transformation to phytohemagglutinin, antigens of Candida albicans, mumps, and streptokinase. Eighteen patients (24.7%) had a hypoergic or anergic response to Candida antigen on skin testing versus two controls (5.4%), p = 0.01. Overall, the patient's lymphoblastic proliferation to mitogen and various antigens was not significantly different from that of the controls. However, a subgroup of younger women (19 to 29 years old) had impaired responses to Candida antigen when compared with age-matched controls, 58% versus 17%, p less than 0.005. Most women with current vaginal moniliasis had normal cellular immunity.

Abstract
Biopsies taken from vulvar lesions in 12 women affected by vulvar lichen sclerosus et atrophicus (LSA) have been processed for immunohistological study. Activated (HLA-Dr+) T cells, associated with CD1a+ accessory cells, were found in the dermis in all cases, with architectural patterns varying in relation to the histological phase (early, well developed, old) of the lesion. Interestingly, the number of epidermal CD1a+ Langerhans cells (LCs) was increased in all cases, without any correlation with the amount of the dermal infiltrate and with the histological phase of the lesions. In fact, also in old lesions the number of epidermal CD1a+ LCs was increased, and the sparse dermal lymphoid cells showed a persistent HLA-Dr antigen expression. These data, indicating the persistent activation of epidermal antigen-presenting cells and lymphoid cells in all the evolutive phases of vulvar LSA, suggest a possible involvement of the skin immune system in the pathogenesis of LSA.

Abstract
Specimens from vulvar carcinomas and vulvar intraepithelial neoplasia (VIN) of various degrees were analyzed for the presence of herpes simplex virus 2 (HSV 2) and human papillomavirus (HPV) genetic information. A search for the HPV 16 E6 protein as well as the HSV 2 antigenic determinant LA1 and ICSP 11/12 protein was carried out with an immunoperoxidase assay on 12 vulvar carcinomas and 6 VINs. Seven invasive cancers and four VINs were screened for the presence of homology to HPV 16 DNA and HSV 2 DNA transforming sequences with Southern blot hybridization. We used specimens from labial tumors and from normal vulvas and cervixes as controls. The preliminary results showed that one vulvar carcinoma and two VINs contained HPV 16 DNA. Four vulvar carcinomas expressed the E6 protein, while all the VINs were negative. Homology to HSV 2 DNA transforming sequences was detected in one vulvar cancer but not in any VIN cases. Positivity to HSV 2 ICSP 11/12 was observed in 33.3% of VIN cases and 75% of invasive cancers. HSV 2 LA1 antigenic determinant was expressed in 33.3% of VIN and 66.6% of cancer cases.

Abstract
The cause of vulvar lichen sclerosus (VLS) is unknown. An autoimmune origin has been suggested. The HLA system is responsible for the synthesis of major histocompatibility antigens and is considered a genetic marker of the risk of or resistance to some diseases. Recently, the association between some antigens of the HLA system and diseases of proven autoimmune origin has been reported. A possible association between antigens of the HLA system and VLS has been investigated by others, with contradictory results. Here we report the results of HLA typing in 68 women with histologically proven VLS. The following antigens were tested: A1, A2, A3, A9-11, A28, A29, A32, B5, B7, B8, B12-B18, B21, B22, B27, B35, B40, Cw1-4, Dr1-5 and Dr7. The results were compared with the frequency of HLA antigens in about 2,000 controls. Patients affected by VLS showed an increased frequency of HLA-B21 (22.06% vs. 9.56%, P less than .001), HLA-Dr5 (55.38% vs. 40.92%, P less than .025) and HLA-Dr7 (38.46% vs. 25.19%, P less than .025). After correction for the number of antigens tested (44) the difference in HLA-B21 frequency was significant at the P less than .05 level. This finding gives further support to the suggestion that an immune system disorder is involved in the origin of VLS.

Antibodies to papillomavirus genus-antigens in women with genital warts. MICROBIOLOGICA 1987; 10:271-9. [PMID: 3041183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 01/03/2023]
Abstract
Thirty-three sera from women symptom-free for papillomatous disease and 27 sera from women with flat or exophytic genital warts were examined for the presence of IgG and IgM antibodies to papillomavirus (PV) genus-antigens. For this purpose, sera were challenged with genus-antigens extracted from both human and bovine purified virions of PVs, in a micro solid-phase enzyme-linked immunosorbent assay (ELISA). The assay performed with PV genus-antigens of human origin showed that in women with genital warts, IgG antibodies were present in a percentage of 70.37% and IgM antibodies in a percentage of 40.74%; in apparently uninfected women, IgG and IgM antibodies were present in a percentage of 54.54% and 24.24% respectively. When sera were challenged with PV genus-antigens of bovine origin for IgG antibody class, positivity was 70.37% in women with genital disease and 45.45% in symptom-free women. IgG and IgM antibody response in women with and without papillomatous genital lesions is discussed.

Abstract
Tissue typing was performed on 25 patients who attended the Royal Victoria Hospital with chronic vulval dystrophy (CVD). Age-matched control groups who had pernicious anaemia only and achlorhydria only were also tissue typed as these conditions had been found more frequently in our patients with CVD. When these three groups were compared with age-matched control groups of blood donors and patients with gynaecological disorders other than CVD, no specific tissue type was found in patients with CVD nor in those with pernicious anaemia or achlorhydria only.

Abstract
A case of Behcet syndrome with immunologic evaluation, including screening of a vulvar ulcer for IgG, IgM, IgA, and fibrinogen by direct fluorescent microscopy is presented. Attempts were made to demonstrate cellular and humoral immune responses to mucosal antigens by lymphoblast transformation in the presence of cadaver esophageal mucosal extracts and indirect immunofluorescence using autologous serum and mucosal tissue. Serial measurements of percentages of total T, active T, and B lymphocyte populations, and lymphocyte response to phytohemagglutinin (PHA) stimulation during the course of Behcet syndrome are also presented. Clinical evaluation, histology of a Behcet vulvar ulcer, and a 2-year followup with good response to chlorambucil are reviewed.
