Scratching or rubbing the itchy patch(es), either frequently or sporadically Delusions of parasitosis occur in disturbed or anxious eccentric individuals. This disorder begins as intractable pruritus with a crawling sensation in the skin. The patients are convinced that they are harboring parasites and usually bring “specimens” to prove infestation. These bits of material or skin must be examined to rule out a true infestation and to assure the patient of your interest in the problem. More than half of these patients have no visible skin lesions. Those with active lesions have excoriated, crusted papules secondary to picking. Illicit drug addiction should also be ruled out. Request Username Although not psoriasiform, mention is made of a recently described entity that clinically resembles lichen simplex chronicus or lichen amyloidosus but which has no histological similarities at all – pretibial pruritic papular dermatitis. The authors of that paper proposed that it was a response to chronic rubbing, possibly with other contributing factors such as xerosis, contact with irritants, and emotional distress. The lesions were red to flesh colored, pruritic papules 3–8 mm in diameter. There was a cobblestone appearance in some later lesions. Lesions were unilateral in 33/44 cases and bilateral in 11/44. The histology showed mild compact orthokeratosis, flattening of the rete ridges, superficial dermal fibrosis, and a mild to moderate superficial and mid-dermal infiltrate of lymphocytes, histiocytes and a few eosinophils. Stellate cells were present, probably a reflection of scratching. The published photomicrographs show some resemblance to pigmented purpuric dermatosis but there was no hemosiderin. Figures Bathing Chan SC Questions to ask your doctor It should be emphasized that during all age periods, neurodermatitis has the leading clinical symptom, it is itching that persists for a long time, even in case of disappearance of skin lesions.

Tacrolimus is a macrolide obtained from Streptomyces, and is widely used as an immunosuppressant in transplant medicine. Skin diseases such as neurodermatitis are another indication; this will be discussed elsewhere (see Chapter 2.17). Certain advantages and disadvantages of tacrolimus in pregnancy are discussed compared to cyclosporine: rejection and hypertension are less common with tacrolimus, and the necessary dosage of prednisolone is lower. On the other hand, gestational diabetes occurs more often, as does transient hyperkalemia and transient reduction of kidney function in the newborn. Jain (1997) even reported on a newborn with anuria which lasted 36 hours. As with other immunosuppressant drugs, pre-eclampsia, prematurity, low birth weight, and cesarian births were seen at greater incidence. Scientists have presented a new drug for smoothing the symptoms of menopause The causes of neurodermatitis are many and varied. Genetic predisposition, environmental factors as well as inflammation taking place in the skin play a role. This reduced skin barrier is caused by a deficiency, an imbalance or defective functioning of substances (e.g. proteins or fats) that are responsible for the formation of the upper layer of the skin. As a result, more water evaporates and the skin becomes dry. In addition, the skin becomes more permeable to allergens and other environmental substances. These can trigger inflammatory reactions.  Topical under occlusion Br J Dermatol. 1998; 138: 182-187 MedlinePlus links to health information from the National Institutes of Health and other federal government agencies.

News See, Play and Learn Meyer S Find & Review Registration Community programs & events Skip to main content FAQs Grundmann-Kollmann M Print this section In the pathogenesis of neurodermatitis as well as eczema, the leading role belongs to a dysfunction of immune, central and autonomic nervous systems. The basis of immunological disorders is a reduction of a number and functional activity of T-lymphocytes, especially T-suppressors, regulating immunoglobulin E synthesis by B-lymphocytes. IgE binds to blood basophiles and mast cells, which start to produce histamine, causing immediate hypersensitivity development.
