Review
Interface dermatitis can be classified based upon the cell type that dominates the infiltrate (ie, neutrophilic, lymphocytic, or lymphohistiocytic) or by the intensity of the interface inflammation. Regarding lymphocytic interface dermatitis, there are 2 broad categories: cell-poor interface dermatitis, when only a sparse infiltrate of inflammatory cells is present along the dermoepidermal junction, or cell rich, which typically occurs as a heavy bandlike infiltrate that obscures the basal layers of the epidermis. In the case of lymphocytic interface dermatitis, the latter is often termed a lichenoid interface dermatitis. This review focuses upon the mononuclear cell-predominant forms of interface dermatitis.

Review
Dermatitis artefacta is a self-inflicted skin disease with a multifactorial aetiology. The condition can be a symptom of an underlying psychiatric condition or a sign of psycho-social stressors. This paper gives an updated view on dermatitis artefacta. The majority of the patients have some form of psychiatric co-morbidity including depression and anxiety. Many have experienced negative life events such as diseases or deaths. Personality disorders were reported in only two studies. Treatment options besides the acute treatment of the skin were psychotherapy and psychotropic drugs.

Review
Exfoliative dermatitis, also known as erythroderma, is an uncommon but serious skin disorder that family physicians must be able to recognize and treat appropriately. Although the etiology is often unknown, exfoliative dermatitis may be the result of a drug reaction or an underlying malignancy. The approach to treatment should include discontinuation of any potentially causative medications and a search for any underlying malignancy. One of the most common malignancies associated with exfoliative dermatitis is cutaneous T-cell lymphoma, which may not manifest for months or even years after the onset of the skin condition. Hospitalization is usually necessary for initial evaluation and treatment. In the hospital, special attention must be given to maintaining temperature control, replacing lost fluids and electrolytes, and preventing and treating infection. The long-term prognosis is good in patients with drug-induced disease, although the course tends to be remitting and relapsing in idiopathic cases. The prognosis of cases associated with malignancy typically depends on the outcome of the underlying malignancy.

Review
Fiddler's neck is a common dermatologic condition associated with instrument use in violin and viola players. It typically manifests as a submandibular and/or supraclavicular lesion. It is a benign condition, but it may be mistaken for lymphedema or a salivary gland malignancy. Otolaryngologists who treat patients with fiddler's neck should be aware of appropriate management protocols and the need to avoid surgical excision. We obtained informed consent from 3 violinists to present their cases as specific examples of fiddler's neck. In addition, we present a literature review based on our PubMed search for articles about this instrument-induced dermatitis. The literature suggests that submandibular fiddler's neck is caused by mechanical pressure and shear stress on the skin and that it can present as erythema, scarring, edema, and lichenification. Supraclavicular fiddler's neck, on the other hand, is caused by allergic contact dermatitis, and it can present as an eczematous, scaly, and/or vesicular lesion. In most cases, a good history (especially of string instrument use), physical examination, and a patch test are sufficient to diagnose this condition. Management of fiddler's neck includes a topical steroid, proper instrument handling, neck padding, changing the instrument's materials, and/or reducing the amount of playing time. Surgical excision is usually not advisable.

Shiitake Dermatitis is a skin eruption that resembles whiplash marks and occurs after consumption of raw shiitake mushrooms. It is caused by a toxic reaction to lentinan, a thermolabil polysaccharide which decomposes upon heating. We report the second case of this dermatitis in Brazil. A 25-year-old man presented with linearly arranged erythematous, pruritic papules on the trunk and limbs, after ingestion of a salad containing raw shiitake mushrooms. The eruption was self-limited, resolving within 10 days of onset. The recognition of this entity gains importance due to the increased consumption of shiitake mushrooms in occidental countries.

Review
Allergic contact dermatitis (ACD) is a type IV delayed hypersensitivity reaction. The gold standard for diagnosis is patch testing. The prevalence of positive patch tests in referred patients with suspected ACD ranges from 27 to 95.6%. The relationship between ACD and atopic dermatitis (AD) is complicated with conflicting reports of prevalence in the literature; however, in a patient with dermatitis not responding to traditional therapies, or with new areas of involvement, ACD should be considered as part of the work-up.

Review
In vivo reflectance confocal microscopy (RCM) is a relatively novel non-invasive tool for microscopic evaluation of the skin used prevalently for diagnosis and management of skin tumour. Its axial resolution, its non-invasive and easy clinical application represents the goals for a large diffusion of this technique. During the last 15 years, RCM has been demonstrated to be able to increase the sensibility and sensitivity of dermoscopy in the diagnosis of skin tumours integrating in real time clinic, dermoscopic and microscopic information useful for the definition of malignancy. Despite to date, no large comparative studies on inflammatory skin diseases has been published in the literature, several papers already showed that RCM has a potential for the evaluation of the descriptive features of the most common inflammatory skin diseases as psoriasis, lupus erythematosus, contact dermatitis and others. The aim of the application of this technique in non-neoplastic skin diseases has been prevalently focused on the possibility of clinical diagnosis confirmation, as well as therapeutic management. Moreover, the use of RCM as driver for an optimised skin biopsy has been also followed in order to reduce the number of unsuccessful histopathological examination. In this review article we describe the confocal features of the major groups of inflammatory skin disorders focusing on psoriasiform dermatitis, interface dermatitis and spongiotic dermatitis.

Review
Dermatitis artefacta is a rarely diagnosed disorder that is often a source of perplexity and anxiety for dermatologists because they know less about the cause of this self-inflicted condition than the patients themselves. It differs from other skin disorders in that diagnosis is made by exclusion rather than on the basis of histologic and biochemical findings and therefore involves a considerable investment of time and resources. Based on the findings of a study of 201 patients diagnosed with dermatitis artefacta between 1976 and 2006, we review the different clinical presentations of this skin disorder and discuss its diagnosis and treatment. The series analyzed comprised 152 women and 49 men (female to male ratio of 3.1:1) with a mean age of 31.2 years. The patients were mostly single and had a low educational level and few or no job qualifications or skills.
