A case of disseminated DLE complicated by atopic dermatitis and Sjögren's syndrome: link between hypohidrosis and skin manifestations.
Summary of "A case of disseminated DLE complicated by atopic dermatitis and Sjögren's syndrome: link between hypohidrosis and skin manifestations."
We report an unusual case of disseminated discoid lupus erythematosus (DLE) complicated by pre-existing atopic dermatitis (AD) and late-onset Sjögren's syndrome (SS). Disseminated DLE lesions were sparse on the expected sites for AD, such as the medial region of the extremities or v-neck area. The patient fulfilled the diagnostic criteria for AD and SS but not for systemic lupus erythematosus. Histopathological analysis of the crusted erythematous lesions revealed typical DLE with few FoxP3(+) cells and a moderate number of IL-17(+) cells. A quantitative sweating test showed impaired sweating of both lesional and non-lesional skin due to underlying hypohidrosis that was related to AD and SS. This finding suggests that dissemination of DLE was triggered by scratching and a Köbner phenomenon-like effect related to hypohidrotic and xerotic skin. To the best of our knowledge, this is the first reported case of disseminated DLE complicated by AD and SS.

Kaposi Varicelliform Eruption
A disseminated vesicular-pustular eruption caused by the herpes simplex virus (HERPESVIRUS HOMINIS), the VACCINIA VIRUS, or Varicella zoster (HERPESVIRUS 3, HUMAN). It is usually superimposed on a preexisting, inactive or active, atopic dermatitis (DERMATITIS, ATOPIC).
The widespread involvement of the skin by a scaly, erythematous dermatitis occurring either as a secondary or reactive process to an underlying cutaneous disorder (e.g., atopic dermatitis, psoriasis, etc.), or as a primary or idiopathic disease. It is often associated with the loss of hair and nails, hyperkeratosis of the palms and soles, and pruritus. (From Dorland, 27th ed)
Antigens from the house dust mites (DERMATOPHAGOIDES), mainly D. farinae and D. pteronyssinus. They are proteins, found in mite feces or mite extracts, that can cause ASTHMA and other allergic diseases such as perennial rhinitis (RHINITIS, ALLERGIC, PERENNIAL) and atopic dermatitis (DERMATITIS, ATOPIC). More than 11 groups of Dermatophagoides ALLERGENS have been defined. Group I allergens, such as Der f I and Der p I from the above two species, are among the strongest mite immunogens in humans.
Rare autosomal recessive disease with variable expressions. Clinical features of the disease include variable ICHTHYOSIFORM ERYTHRODERMA, CONGENITAL; bamboo hair (trichorrhexis invaginata); and ATOPIC DERMATITIS. The disease is caused by mutations in the SPINK5 gene.
A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.
We describe here 4 patients with Sézary syndrome masquerading as adult-onset atopic dermatitis. The patients presented with a clinical picture compatible with wide-spread atopic dermatitis and did no...
Many authors favor a distinction between the extrinsic and intrinsic forms of atopic dermatitis. In this review, the controversy is discussed and several definitions are presented. After reviewing man...
Th-2-biased immune responses are known to play a key role in the pathogenesis of atopic dermatitis. In particular, the macrophage-derived chemokine CCL22 is directly implicated in Th-2-associated skin...
OBJECTIVES: The aim of this study was to assess the point prevalences of hay fever, asthma, and atopic dermatitis in OA, RA, and AS, and to compare with healthy controls. METHODS: A total of 935 patie...
Personality and emotional factors are supposed to influence the course of skin diseases, such as psoriasis and atopic dermatitis. Few reports exist, however, showing distinct personality traits among...
The purpose of this research study is to better understand how this study drug works when people use it to treat atopic dermatitis. Desonate has been approved by the US Food and Drug Admi...
The purpose of the study is to determine whether the topical application of BRT-FC-83C is effective in the treatment of mild to moderate atopic dermatitis.
The purpose of this research study is to better understand how the study drug works when people use it to treat atopic dermatitis.
The primary goal of the study is to investigate the impact of a common genetic polymorphism in a histamine detoxification enzyme that may well have a common role in regulating the expressi...
Atopic Dermatitis is a chronic non contagious disease that causes itchy, inflamed skin. The purpose of this study is to evaluate the safety and efficacy of topical AS101 ointment for the t...
