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...

Atopic dermatitis is a complex, systemic inflammatory disorder associated with a variety of clinical features. The original criteria of Hanifin and Rajka include major criteria and a list of about two dozen minor criteria however, even the minor criteria do not include some features of atopic dermatitis noted less commonly but still seen with some frequency. This contribution first reviews the common clinical appearance of atopic dermatitis in infancy, childhood, and adulthood, as well as the less typical appearances, including lichenoid atopic dermatitis; juvenile plantar dermatosis; nummular-type atopic dermatitis; follicular atopic dermatitis; alopecia of atopic dermatitis; eczema coxsackium; and psoriasiform, perineal, and lip licker's dermatitis...

An otherwise healthy 36-year-old Caucasian woman, without prior history of atopic dermatitis or eczema, presented to an outside dermatologist with a generalized, severely pruritic eruption involving the entire body except the face. One month previously, she had used a 50% trichloroacetic acid tattoo removal solution on a blue-colored tattoo on the medial aspect of the left ankle. The patient's eruption persisted for 7 months, and after several attempts to slowly taper her prednisone dose, she presented to our institution...

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...

Atopic dermatitis therapy can be a challenge in many cases. Persistence into adulthood often reflects the more severe cases and such patients have the added problems of hand eczema and thick nummular lesions that resist topical medications. Within this group are patients labeled as having adult-onset atopic dermatitis, a designation that is hard to define and probably represents those whose childhood eczema was simply forgotten. Management is difficult for most adult cases and should not be diverted by questionable labels...

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)...

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: Allergic contact dermatitis is a well-known cause of hand eczema, although the influence of contact allergens on different clinical types of hand eczema remains still unclear. OBJECTIVE: To identify most common positive tested allergens among hand eczema patients and to define the relation between specific contact allergies and clinical types of hand eczema according to the guidelines of the Danish Contact Dermatitis Group (DCDG). METHODS: We included 1571 hand eczema subjects who were patch tested from 1 January 2002 to 31 December 2013...

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...

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...
