There is a large body of literature demonstrating an important role of mast cells in adaptive and innate immunity. The distribution of mast cells in the skin varies in different parts of the body. It is well known that mast cells are important for effector functions of classic IgE-associated allergic disorders as well as in host defense against infective agents and influence the manifestation o...

The neurophysiology of itch, the dominant symptom of skin disease, has previously received scant attention. Recent advances in the neurophysiology and molecular basis of itch include the use of microneurography to demonstrate the existence of a subset of itch-dedicated afferent C neurons distinct from neurons which transmit pain; use of functional positron emission tomography (PET) and magnetic...

Background: Vulvar dermatoses are inflammatory disorders of genital skin causing itch, burning, and plaques with overlying excoriation and linear fissures. Objective: To assess the effectiveness of a soft foam based on Tiab® system (TF), complex of titanium micro crystals covalently bound with silver ions associated with hyaluronic acid, in the supportive treatment of lichen sclerosus (LS) and ...

Lichen sclerosus, lichen planus, and lichen simplex chronicus are three of the most common non-neoplastic epithelial disorders of the vulva. Lichen sclerosus is characterized by intense vulvar itching and can affect men and women of all ages, but it manifests most commonly in postmenopausal women. Patients with lichen sclerosus have an increased risk of developing squamous cell carcinoma, and t...

Repeated courses of potent topical corticosteroids and maintenance therapy with moderately potent topical corticosteroids are frequently needed to treat various forms of vulvar dermatoses, which are often characterized by an abnormal proliferation or activation of T lymphocytes. Because such therapeutic regimen is associated with an increased risk of potential side effects, particularly skin at...

The dysregulation of apoptosis occurs in many cutaneous disease states. Several apoptosis inhibitors have been shown elevated in neoplasms and in some inflammatory conditions, but their relation to proliferative and apoptotic states has not been defined. We examined the expression of the apoptosis inhibitor survivin in a panel of keratinocytic neoplasms and hyperproliferative skin lesions using...

INTRODUCTION Dermatologic diseases of the vulva may cause dyspareunia. These disorders may be overlooked by gynecologists and urologists because of lack of residency training experience. Dermatologists who are most familiar with these diseases are infrequently trained in vulvovaginal examination. As such, these disorders are often improperly diagnosed and treated. AIM To describe the presenta...

Results The lesions started at age 18 during the patient ́s first pregnancy and had a predominant flexural distribution pattern. At the physical exam, the patient presented with erythema and infiltrative lesions in forearm and periorbital regions, and scaly erythematous papules, especially in inferior extremities. Some of these lesions presented an ulcerous center and had linear form. The patien...
