Psoriasis vulgaris is a multifactorial, heterogeneous disease that is associated with problems in skin image and feelings of shame and stigmatization. The aim of this study was to analyze psychopathological traits in patients with psoriasis and a comparative group. A total of 254 dermatological patients participated in the study: 124 patients with confirmed diagnoses of psoriasis vulgaris and 130 patients with melanocytic and non-melanocytic nevi on covered parts of the body. Psychometrically mensural and standardized instruments were used in the study: list of general data, appendix of disease data, Beck Depression Inventory test, State-Trait Anxiety Inventory, Measure of psychological stress and Eysenck's Personal Questionnaire. There is a significant statistical difference in the result of psychometric tests between the study groups. Patients with psoriasis have more severe symptoms of depression, more physical symptoms of anxiety and higher results on the anxiety scale as a state and as a trait p=0.000. Eysenck's personal questionnaire showed higher results on the psychoticism scale p=0.000 and lower results on the extraversion scale p=0.035 among psoriatic patients.

Inflammatory linear verrucous epidermal nevus is a variant of verrucous epidermal nevus, characterized by recurrent inflammatory phenomena. Despite well-established clinical manifestations, the differential diagnosis between inflammatory linear verrucous epidermal nevus and linear psoriasis remains difficult. Clinical history, physical examination and histopathology analysis may not be sufficient to confirm the diagnosis. We report the case of a 4-year-old girl in which the involucrin immunostaining was helpful in the diagnosis of inflammatory linear verrucous epidermal nevus. Our findings confirm that involucrin immunohistochemistry is a useful tool in such cases.

Inflammatory linear verrucous epidermal nevus (ILVEN) is a pruritic, erythematous scaly epidermal nevus which follows a Blaschko's lines. Lichen striatus, linear Darier disease, linear porokeratosis, linear lichen planus, linear psoriasis, and the verrucous stage of incontinentia pigmenti may all have similar clinical presentations as the linear verrucous epidermal nevus. ILVEN can be distinguished from true nevoid psoriasis by pruritus and lack of response to antipsoriatic treatments. Various therapeutic modalities have been described, but no one therapy has been successful consistently. Though giant ILVEN is a relative contraindication to surgical excision, here we report a case showing effectiveness of full thickness excision and skin grafting for this condition.

Inflammatory linear verrucous epidermal nevus (ILVEN) is a benign cutaneous hamartoma characterized by intensely erythematous, pruritic, and inflammatory papules that occur as linear bands along the lines of Blaschko. There is a considerable clinical and histological resemblance between ILVEN and linear psoriasis, lichen striatus, linear lichen planus, and invasion of epidermal nevus by psoriasis. The pathogenesis of ILVEN is unknown. It is regarded as a genetic dyskeratotic disease reflecting genetic mosaicism. Here, a case of vulvar and perianal condyloma superimposed ILVEN is presented.

Basal cell naevus syndrome is an inherited autosomal dominant genetic disorder characterised by multiple basal cell carcinomas (BCC), skeletal, neurological and opthalmological abnormalities. The treatment of choice of the often multiple and large BCC consists of a combined approach including surgery, liquid nitrogen and other topical treatment modalities. Imiquimod 5% cream is an immune-response-modifying drug with antiviral and anti-tumour activity. Recent reports have associated the immune-stimulant properties of imiquimod with the exacerbation of several autoimmune skin diseases, such as eczema, psoriasis, vitiligo and lichenoid dermatitis. Here we report a patient with basal cell naevus syndrome who developed a lichen planopilaris on the same site of the scalp, which had been previously treated with two cycles of imiquimod for multiple BCC.

Pigmented and non-pigmented nail alterations are a frequent challenge for dermatologists. A profound knowledge of clinical and dermatoscopic features of nail disorders is crucial because a range of differential diagnoses and even potentially life-threatening diseases are possible underlying causes. Nail matrix melanocytes of unaffected individuals are in a dormant state, and, therefore, fingernails and toenails physiologically are non-pigmented. The formation of continuous, longitudinal pigmented streaks (longitudinal melanonychia) may either be caused by a benign activation of matrix melanocytes (e.g., as a result of trauma, inflammation, or adverse drug reactions) or by a true melanocytic proliferation (e.g., in a nevus or melanoma). In general, non-continuous nail alterations, affecting only limited parts of the nail apparatus, are most frequently of non-melanocytic origin. Important and common differential diagnoses in these cases are subungual hemorrhage or onychomycosis. In addition, foreign bodies, bacterial infections, traumatic injuries, or artificial discolorations of the nail unit may less frequently cause non-continuous nail alterations. Many systemic diseases that may also show involvement of the nails (e.g., psoriasis, atopic dermatitis, lichen planus, alopecia areata) tend to induce alterations in numerous if not all nails of the hands and feet. A similar extensive and generalized alteration of nails has been reported after treatment with a number of systemic drugs, especially antibiotics and cytostatics. Benign or malignant neoplasms that may also affect the nail unit include glomus tumor, Bowen's disease, squamous cell carcinoma, and rare collision tumors. This review aims to assist clinicians in correctly evaluating and diagnosing nail disorders with the help of dermatoscopy.

Lipomatous metaplasia is an uncommon phenomenon. After identifying the presence of a band of adipocytes in the superficial reticular dermis underlying two excisions for basal cell carcinoma, we prospectively reviewed all skin specimens accessioned in our laboratory over a 6-month period and identified eight additional cases. In each example there was a band of adipocytes in the upper dermis, at the level of solar elastosis that was widely separated from the subcutaneous fat by a normal appearing reticular dermis. The cells were positive for S100 and negative for CD163. No connection between the superficial band of adipocytes and the subcutaneous or periappendageal fat was seen. The alterations were flat in configuration without polypoid changes. Eyerich et al. reported lipomatous metaplasia in the dermis of a patient with acute generalized exanthematic pustulosis and psoriasis, and postulated this to be a postinflammatory phenomenon. Fatty metaplasia occurs within a variety of cutaneous neoplasms including nevi, adnexal tumors and peripheral nerve sheath tumors. However, superficial dermal fatty metaplasia beneath cutaneous neoplasms is a newly described phenomenon and we suspect this process represents fatty metaplasia within solar elastosis and that it may occur more frequently than recognized.

Mosaic disorders can most easily be studied in the skin. This article presents a comprehensive overview of the different forms of cutaneous mosaicism. Major categories are genomic versus epigenetic mosaicism and nonsegmental versus segmental mosaicism. The class of nonsegmental mosaics includes single point mosaicism as exemplified by solitary benign or malignant skin tumors; disseminated mosaicism as noted in autosomal dominant tumor syndromes such as neurofibromatosis 1; and patchy mosaicism without midline separation as found in giant melanocytic nevus. The class of segmental mosaics includes segmental manifestation of lethal genes surviving by mosaicism as noted in Proteus syndrome; type 1 segmental mosaicism of autosomal dominant skin disorders reflecting heterozygosity for a postzygotic new mutation; type 2 segmental mosaicism of autosomal dominant skin disorders reflecting loss of heterozygosity that occurred at an early developmental stage in a heterozygous embryo; and isolated or superimposed segmental mosaicism of common polygenic skin disorders such as psoriasis or atopic dermatitis. A particular form of genomic mosaicism is didymosis (twin spotting). Revertant mosaicism is recognizable as one or more areas of healthy skin in patients with epidermolysis bullosa or other serious genodermatoses. The category of epigenetic mosaicism includes several X-linked, male lethal disorders such as incontinentia pigmenti, and the patterns of lyonization as noted in X-linked non-lethal disorders such as hypohidrotic ectodermal dysplasia of the Christ-Siemens-Touraine type. An interesting field of future research will be the concept of epigenetic autosomal mosaicism that may explain some unusual cases of autosomal transmission of linear hypo- or hypermelanosis.

Melanoma occurrence during treatment with anti-tumor necrosis factor is considered an incidental event, although very recent studies suggest a risk. Etanercept is a fusion protein that binds the tumor necrosis factor receptor and is included among TNF inhibitors, approved for the treatment of several autoimmune diseases, such as psoriasis.We described a 79-year-old man with psoriasis, being treated with etanercept, who presented with a new brown to black macule on his right shoulder; this was immediately surgically excised. Histology showed a superficial spreading melanoma, 1.2 mm Breslow thickness, one mitosis/hpf, with no vascular or neural invasion (stage T2b). Sentinel lymph node biopsy was negative. There were no apparent melanoma risk factors: normal total nevus count, photo type IV, no childhood sunburns, no family history of melanoma, and no previous immune suppressive drugs and/or phototherapies. Etanercept 50 mg/week had been administered continuously for 5 years before the melanoma occurrence. After etanercept withdrawal his psoriasis slowly, but progressively relapsed.

Inflammatory linear verrucous epidermal nevus (ILVEN) is a relatively rare disorder with an onset at early age, consisting of pruritic linear papules and/or plaques and histologic features resembling psoriasis or lichenoid dermatitis. The disease is a version of mosaicism caused by somatic mutations. ILVEN belongs to the heterogeneous group of congenital hamartomas of embryonal ectodermal origin, as a variant of verrucous epidermal nevus, representing approximately 5% of all epidermal nevi, with predominance in females and with general therapeutic resistance. We report on an 18-month-old female patient with ILVEN, who failed to respond to topical tacrolimus, but achieved complete resolution with topical application of momethasone furoate 0.1% under occlusion for 2 weeks, with no signs of recurrence to date. Consequent topical therapy can provide excellent results in young children.
