Jun Yeong Park, Eun Byul Cho, Eun Joo Park, Hye Rim Park, Kwang Ho Kim, Kwang Joong Kim
BACKGROUND: The histopathologic differences among palmar psoriasis (PP), hand eczema (HE), and hyperkeratotic hand dermatitis (HHD) have been poorly described. OBJECTIVES: We sought to distinguish among PP, HE, and HHD on a histopathologic basis. METHODS: We retrospectively analyzed the histology of hematoxylin-eosin-stained sections obtained from 96 patients diagnosed with PP, HE, or HHD. RESULTS: The patients were divided into 4 subgroups: PP (n = 16, group A), HE without atopic or nummular dermatitis (n = 41, group B), HE with atopic or nummular dermatitis (n = 14, group C), and HHD (n = 25, group D)...

Nummular eczema or dermatitis is an uncommon paediatric pathology. It is presented as red-purplish small papules and vesicles that join to form exudative circular patches and then to eczematous or lichenified patches with discoid shape. The lesions appear predominantly on the extensor surface of extremities, although they can appear in trunk, hands or feet. This pathology has a clinical diagnosis; only few cases require complementary test. The topical corticosteroids are the mainstay of the treatment, and the causal treatment whether an infectious trigger is found...

For many years, the biblical term tzaraat has referred to leprosy. In fact, the disease or diseases described under this name have no relationship to leprosy, as it was known in the Middle Ages or today; moreover, the term referred not only to skin disease, but also to the state of the ritual impurity and punishment for the sins. Although the real nature of tzaraat remains unknown, the differential diagnosis might include the following: Psoriasis, seborrheic dermatitis, favus, dermatophyte infections, nummular dermatitis, atopic dermatitis, pityriasis rosea, crusted scabies, syphilis, impetigo, sycosis barbae, alopecia areata, furuncles, scabies, neurodermatitis, scarlet fever, lupus erythematosus, lichen sclerosus et atrophicus, folliculitis decalvans, morphea, sarcoidosis, and lichen planopilaris...

BACKGROUND: Glucocorticoids (GC) are the most commonly used anti-inflammatory drugs in dermatology. The actions of GCs are mediated by the glucocorticoid receptor (GR). Alternative splicing of GR mRNA gives rise to different isoforms, GRα and GRβ being the most important. GRβ antagonizes the activity of GRα and its up-regulation has been associated with glucocorticoid insensitivity in several non-cutaneous inflammatory diseases. METHODS: Using immunohistochemical stainings, we analyzed the expression of GRα and GRβ in lesional skin samples of patients with atopic dermatitis, lichen ruber planus, eczema nummulare and lichen simplex chronicus...

The Dutch College of General Practitioners practice guideline 'Eczema' provides recommendations for the diagnosis and treatment of common types of eczema: atopic dermatitis, contact dermatitis, acro-vesicular eczema, nummular eczema, hypostatic eczema, and asteatotic eczema. Age is an important factor when determining the type of eczema. According to the guideline, patient history and physical examination are sufficient in the diagnosis of eczema; additional investigations are rarely indicated. Moisturizing the skin with neutral emollients is the cornerstone of treatment for patients with eczema...

BACKGROUND: Nummular eczema is an idiopathic inflammatory skin disease that mostly has a chronic and relapsing course. Many factors are thought to be responsible for this condition, such as atopic dermatitis, dry skin, emotional stress or seasonal variation. OBJECTIVE: The purpose of the study was to assess clinical findings and aggravating factors of nummular eczema and to evaluate characteristics, severity of disease and quality of life of patients. METHODS: One hundred patients aged from 18 years old diagnosed as nummular eczema were asked about general data, characteristics and clinical findings of nummular eczema, and completed the Thai version of the Dermatology Life Quality Index (DLQI) questionnaires...

BACKGROUND: Etiopathogenesis of nummular eczema is obscure; many causative factors have been proposed. Only a few studies investigated the relevance of contact allergy. OBJECTIVE: This retrospective study aimed to investigate the role of contact allergy in the underlying mechanism of nummular eczema. METHODS: From the 29,323 consecutive patients, we patch-tested for eczematous dermatitis of various type, 1022 (3.5%) with nummular eczema were enrolled...

OBJECTIVES: There are no known reports of the frequency of skin diseases endemic to rural Yucatan, Mexico. The aim of this study was to report the prevalence of dermatologic conditions in rural villages in that region. METHODS: We conducted a retrospective descriptive study of all cases of skin disease diagnosed by a team of American board-certified dermatologists during consultations in January 2009, August 2009, and June 2010, in the state of Yucatan, Mexico. Traveling clinics were held in eight different rural locations...

The common manifestations of atopic dermatitis (AD) appear sequentially with involvement of the cheeks in infancy, flexural extremities in childhood, and hands in adulthood. Although less common clinical manifestations are well described, they have not been the subject of epidemiologic studies to describe their prevalence in specific age groups. This observational, cross-sectional, comparative study included 131 children younger than 18 of both sexes with AD who attended the clinics of the Dermatology Department of the National Institute of Pediatrics in Mexico City...

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 of autoimmune diseases. We aimed to quantify mast cells in five common dermatoses and compare them statistically with respect to the immunostains...

BACKGROUND: Most study concerning the prevalence and dermatological manifestations of the extrinsic and the intrinsic form of atopic dermatitis (AD) were performed in children and adult AD related to the early-onset AD extending to adult life. Adult-onset AD is a subgroup of AD. Apart from the typical eczematous flexural distribution pattern of AD, this group may also have nontypical morphology and localization. OBJECTIVE: The purpose of this study was to compare the clinical and diagnostic features of Thai patients with extrinsic and intrinsic type of adult-onset AD...

BACKGROUND: The reason psoriasis (PSO) favors extensor skin is unknown. We hypothesized that PSO may involve extensor skin preferentially because of differences in the number or type of dermal dendritic cells (dDCs) between flexural and extensor skin. OBJECTIVE: We sought to compare dDC type and distribution in normal-appearing flexural and extensor skin, PSO, and nummular dermatitis (ND). METHODS: Using immunohistochemical markers, the number, distribution, and type of Langerhans cells, myeloid dendritic cells (DCs), and plasmacytoid DCs was compared in normal-appearing skin, PSO, and ND...

Common shapes encountered in dermatologic diseases include linear, nummular, annular, polycyclic, and arciform. The last three have a relatively restricted differential, which must be entirely explored. It is not uncommon for a single disease to present in annular, arciform or polycyclic configurations; moreover, the lesions may evolve from being arciform to annular and then become polycyclic. Regardless, recognizing the arrangement of the defect will undoubtedly help in making a diagnosis and guiding subsequent management...

BACKGROUND: Hanifin and Rajka's criteria (HRC) are the gold standard for the diagnosis of atopic dermatitis (AD). Apart from the age-related distribution and typical morphology of the lesions as defined in one of the major criteria of HRC, patients may also show nontypical morphology and localization. AIM: The aim of this study was to find the frequency of nontypical morphology and localization in Turkish AD patients with onset before the age of 18 years, who were diagnosed according to HRC...

Atopic dermatitis (AD) is a common disease affecting both children and adults. AD develops from a complex interplay between environmental, genetic, immunologic and biochemical factors. Genetic factors predispose atopic subjects to mount exaggerated Th2 responses and to a poorly efficient epidermal barrier, which may be sufficient to initiate inflammation in the skin and may favor allergic sensitization. Thus AD can present with different clinical pheno-types. AD is classically distinguished into an intrinsic and extrinsic form, which are clinically identical but the former lacks high level specific IgE and is not associated with respiratory atopy...

Carcinoembryonic antigen-related cellular adhesion molecule 1 (CEACAM1) is a cell-surface glycoprotein, belonging to the carcinoembryonic antigen family, expressed by human neutrophils, epithelial cells, activated T and NK cells. CEACAM1 is expressed as a cell-surface molecule with different isoforms or can be secreted as a soluble protein. Here, we show that keratinocytes in the outer epidermal layer of psoriatic skin express CEACAM1, unlike those in healthy skin or in cutaneous lesions of patients with atopic or nummular dermatitis...

Triclosan is a lypophilic chlorophenol biocide with broad-spectrum antibacterial and antifungal activity. Triclosan-based topical products have been shown to be tolerated and beneficial in atopic dermatitis. The aim of this study was to evaluate the sensitizing potential of triclosan and triclosan-based creams in patients affected by eczematous dermatitis. Two hundred and seventy-five patients affected by chronic eczema (allergic contact dermatitis, irritant contact dermatitis, atopic eczema, nummular eczema, stasis dermatitis) were patch tested with standard patch test series as well as triclosan and triclosan-based products...
