OBJECTIVE: To characterize the immunohistopathologic features of oral chronic graft-versus-host disease (cGVHD), and the impact of topical immunomodulatory therapy on the infiltrating cells. MATERIAL AND METHODS: Paired oral cGVHD biopsies obtained before (n=12) and one month after treatment (n=12) with topical dexamethasone (n=8) or tacrolimus (n=4) were characterized by immunohistochemistry using a panel of CD1a, CD3, CD4, CD8, CD20, CD31, CD62E, CD103, CD163, c-kit and FoxP3...

To determine if vestibulovaginal sclerosis and lichen sclerosus (LS) are 2 distinct entities. Biopsies obtained from the vagina or vulvar vestibule that contained abnormal subepithelial collagen were reviewed. Cases were categorized either as LS or vestibulovaginal sclerosis based on presence or absence of basal layer degeneration and lymphocytic infiltrate. Clinical data collected included examination findings, biopsy site and indication, previous vulvovaginal surgery, medications at time of biopsy, vulvar LS, treatment, and response...

Penile cancer is a rare neoplasm representing less than 1% of all malignancies in the USA and Europe but is a significant public health hazard in the developing world. Male neonatal circumcision has been associated with a dramatic decrease in penile cancer rates with countries such as Israel, where circumcision is widely performed, having the lowest incidence in the world at <0.1% of malignancies. Many risk factors have been identified for penile cancer including phimosis, lack of circumcision, obesity, lichen sclerosis, chronic inflammation, smoking, UVA phototherapy, socioeconomic status, human papillomavirus (HPV) infection and immune compromised states...

Autoimmunity is a status that immune mechanisms react against self-structure. The immune mechanisms, including cellular and molecular elements have been developed to immune body against foreign invades. Multiple factors such as genetic and epigenetic background, hormonal status, microbiome, and other factors can cause launching the autoreactive responses, in which the immune tolerance breaks and immune mechanisms are against self-antigens. Apoptosis is one of the important mechanisms in maintaining the tolerance and eliminating the autoreactive lymphocyte clones...

INTRODUCTION: Tubularized urethroplasty is commonly performed in clinical practice using genital skin flaps, bladder mucosa, and buccal mucosa. However, the long-term effects are not satisfying, and donor site morbidities remain a problem. Besides, those grafts are unavailable with malignant conditions of the urinary tract, a history of lichen sclerosis, or oral disease. OBJECTIVE: An autologous granulation tissue tube of any required length and diameter can be produced by implanting foreign objects subcutaneously (Summary Fig...

Lipotransfer for soft tissue filling is a well-established plastic and aesthetic surgical technique. Elective fat grafting is considered a safe and well-tolerated procedure. Coleman and others have reported that fat grafting may have tissue regenerative properties and not only serve as a soft tissue filler. There have been reports from our group and others that it may improve fibrosis secondary to many different pathological aetiologies including scleroderma, burn injury, lichen sclerosis, graft vs host disease, and radiation...

Vulvovaginitis is one of the most common gynecological complaints presenting in the pediatric and adolescent female. The common causes of vulvovaginitis in the pediatric patient differ than that considered in adolescent females. When a child present with vulvar itching, burning and irritation the most common etiology is non-specific and hygiene measures are recommended. However these symptoms can mimic more serious etiologies including infection, labial adhesion, lichen sclerosis, pinworms and foreign body must be considered...

PURPOSE: We examined the impact on urethral stricture complexity at urethroplasty of previous transurethral treatments such as dilation, urethrotomy, and stenting which are used most commonly when treating male urethral stricture. PATIENTS AND METHODS: We retrospectively reviewed the records of 45 males who had undergone transurethral treatments before urethroplasty and compared their urethrography findings at initial diagnosis with those at urethroplasty. Males with failed hypospadias repair, lichen sclerosis, or history of prior urethroplasty were excluded...

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...
