BACKGROUND: Hormonal fluctuations during menopause lead to endocrine changes in women, especially in their sex steroid hormone production. Studies have documented the role of estrogen and progesterone (Pg) on autoimmune disorders such as multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. Lichen planus (LP), an autoimmune disorder, seen frequently in perimenopausal women, may also get affected by sex steroid hormones, but no direct relationship has been established yet...

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

Survivin is a protein functionally important for cell division, apoptosis, and possibly, for micro-RNA biogenesis. It is an established marker of malignant cell transformation. In non-malignant conditions, the unique properties of survivin make it indispensable for homeostasis of the immune system. Indeed, it is required for the innate and adaptive immune responses, controlling differentiation and maintenance of CD4(+) and CD8(+) memory T-cells, and in B cell maturation. Recently, survivin has emerged as an important player in the pathogenesis of autoimmune diseases...

Cutaneous chronic graft-versus-host disease (GvHD) has a broad spectrum of clinicopathological presentations, the most common ones being poikiloderma, lichen planus-like eruptions, lichen sclerosus-like lesions, morphea-like plaques, and deep sclerosis. New forms of chronic cutaneous GvHD with different clinicopathological characteristics have been described, most of them mimicking cutaneous manifestations of autoimmune diseases. We report the case of a 35-year-old man who underwent allogenic stem cell transplantation for a therapy-associated acute myeloid leukemia and developed an acute GvHD with involvement of skin and gastrointestinal tract...

Labial fusion usually affects prepubertal girls and postmenopausal women, it may rarely occurs in reproductive years in the absence of predisposing factors such as vulvar infections, dermatitis, trauma, female circumcision and lichen sclerosis. Should be considered in differential diagnosis in the differential diagnosis of urinary retention even if the patient doesn't have history of sexual intercourse.

Dermatofibrosarcoma protuberans (DFSP) is an uncommon, low-to-intermediate grade sarcoma with several histologic variants, including pigmented (Bednar tumor), sclerosing, myxoid, atrophic, and DFSP with fibrosarcomatous changes. Two patterns of sclerosis in DFSP can be observed, a sclerotic fibroma-like pattern and a morphea/lichen sclerosus-like pattern. Partial biopsies of sclerosing DFSPs with the sclerotic fibroma pattern can be misdiagnosed as sclerotic fibroma or other benign sclerosing tumors (eg, perineurioma, dermatofibroma)...

Lichen sclerosis (LS) is a chronic, relapsing disease with a variable presentation. In men, genitourinary LS may affect the penile foreskin, glans, meatus, and urethra. Treatment is multifaceted, ranging from pharmacotherapy to surgery. Urethral reconstruction due to stricture disease from LS is frequently plagued by a high recurrence rate. At the authors' institution, the high recurrence rate has shifted their practice toward potent steroids and minimally invasive surgical techniques. Management of recurrence includes dilation, meatotomy/meatoplasty, 1-stage and 2-stage repairs...

Lichen sclerosus et atrophicus and limited systemic scleroderma (acrosclerosis) are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically. They are very rarely associated. The literature has reported cases in which lichen sclerosus was associated with various forms of scleroderma, but often with localized morphea. The characteristic histopathological picture of lichen sclerosus includes a thin epidermis, with orthohyperkeratosis and vascular degeneration in the basal layer, loss of elastic fibers, and band-like inflammatory infiltrate in the papillary dermis, while systemic sclerosis is characterized by excessive deposition of collagen in the dermis, accompanied by reduction in adnexal structures and their entrapment in collagen, and the presence of perivascular lymphocytic inflammatory infiltrate...

Lichen sclerosus is a chronic inflammatory disease associated with substantial morbidity. Knowledge of the aetiology and progression of lichen sclerosus is therefore needed. In this cross-sectional study, 100 male patients diagnosed with lichen sclerosus were interviewed and examined. Since there is a possible link between lichen sclerosus and autoimmunity, blood tests were analysed for thyroid disease, antinuclear antibodies and antibodies to extracellular matrix protein 1, but autoimmunity was found to be infrequent...

Programmed death-ligand 1 (PD-L1) can reduce the immune response by inhibiting CD8 T-cell proliferation and cytotoxic activity. We studied a series of human viral (molloscum, human papillomavirus, herpes simplex, cytomegalovirus, Epstein-Barr virus, smallpox) and bacterial infections (Helicobacter pylori) for the in situ expression of PD-L1, mononuclear cell infiltration, and CD8 activity and compared this to noninfectious idiopathic inflammatory conditions to better define which immune responses may be more highly correlated with an infectious agent...

BACKGROUND: Vulvodynia is a difficult-to-treat, chronic, multifactorial malady that drastically lowers the quality of life of afflicted patients. CASE: A 68-year-old woman, who had been treated successfully for vulvodynia years before with medication, returned with a recurrence of vulvodynia symptoms that this time did not respond to treatment. She now had biopsy-confirmed lichen sclerosis and was found to have markedly elevated serum testosterone levels. An imaging study detected an ovarian lesion that, on removal, proved to be afibrothecoma...

OBJECTIVE: In this study, we investigated if the presence of histologically abnormal epithelium adjacent to the primary tumour influenced the frequency, timing, and topography of local vulvar recurrences (LVR) following treatment for squamous cell carcinoma of the vulva (VSCC). METHODS: The study population comprised a cohort of 201 consecutive cases with incident VSCC. LVR were categorised as local relapses (LR) if they occurred <2cm from the tumour margins, and as second field tumours (SFT) when ≥2cm from these margins...

Newborn male circumcision is a minor surgical procedure that has generated significant controversy. Accumulating evidence supports significant health benefits, most notably reductions in urinary tract infections, acquisition of HIV and a number of other sexually transmitted infections, penile cancer, phimosis, paraphimosis, balanitis and lichen sclerosis. While circumcision, like any surgical procedure, has risks for complications, they occur in less than 1 in 500 infants circumcised and most are minor and require minimal intervention...

AIMS: Differentiating between human papilloma virus-dependent vulvar low-grade and high-grade squamous intraepithelial lesions (LSILs and HSILs) remains difficult in selected cases. Stathmin, a protein involved in cell cycle progression, might be a useful additional marker for this differentiation. The aim of this study was to investigate the additional diagnostic value of stathmin expression in vulvar intraepithelial neoplastic (VIN) lesions. METHODS: Immunohistochemical analysis was used to evaluate stathmin, P16 and Ki67 expression in 91 samples, including LSILs (n=16), HSILs (n=50), differentiated VIN (dVIN; n=10), lichen sclerosis (LS; n=10) and normal vulvar tissue (n=5)...

CONTEXT: Pathogenesis of autoimmune diseases (AD) is one of a multifactorial milieu. A genetic predisposition, an immune system failure, hormonal imbalance and environmental factors play important roles. Among the many environmental factors, the role of infection is gaining importance in the pathogenesis of various autoimmune disorders; among them, Epstein-Barr virus (EBV) plays a pivotal role. Literature states an association of various AD with EBV namely multiple sclerosis, autoimmune thyroiditis, systemic lupus erythematous, oral lichen planus (OLP), rheumatoid arthritis (RA), autoimmune hepatitis, Sjögren's syndrome and Kawasaki disease; among these, the most commonly occurring are OLP and RA...
