Lichen aureus (LA) is a variant of pigmented purpuric dermatosis that is characterized clinically by rust macules, papules or plaques, mainly on the legs. In some cases, LA can be difficult to be distinguished from nummular eczema (NE) with the naked eye. Dermoscopy can be applied to skin lesions, revealing additional features that can be highly valuable for correct diagnosis. This study was conducted to investigate characteristic dermoscopic findings of LA and to identify distinctive features that can differentiate it from NE...

Follicular malignant melanoma (FMM) is an exceedingly rare variant of melanoma. Only 8 cases have been reported in the literature thus far. Often bland on physical examination, FMM shows a striking histologic pattern, with atypical melanocytes sometimes consuming the entire follicle and extending into the dermis. Criteria have been suggested to help distinguish FMM from lentigo maligna melanoma; however, no clear criteria distinguish this cancer clinically. FMM cannot be distinguished from follicular metastases of melanoma based on histology, requiring close clinical correlation and detailed history taking on the part of the practitioner...

Molluscum contagiosum is a viral infection of the epidermis characterized by skin-colored papules or nodules frequently with a central depression. Atypical variants may occur, primarily in immunosuppressed individuals. We here report a case of »giant Molluscum contagiosum« in an immunocompetent child. The patient was presented with a fairly smooth nodule of 2 cm in diameter on the ring finger. Molluscipoxvirus-like virus particles were detected by electron microscopy from the nodule, but since the clinical picture was not compatible with MC, next generation sequencing was performed in order to verify the diagnosis...

We report a unique case of probable drug-induced CD30-positive lymphomatoid reaction. A 58-year-old woman presented with bilateral facial eruptions of 3 weeks duration composed of erythematosus papules in a linear distribution. The pathological features demonstrated a dense dermal and follicular infiltrate of many medium- to large-sized atypical CD30-positive lymphoid cells. The rash resolved rapidly after discontinuation of her medication 1 week later and did not recur. This case highlights the importance of clinicopathological correlation...

Prurigo nodularis (PN) is an intensely pruriginous dermatological disorder whose treatment is challenging for dermatologists. It is characterized by eruptions of papules and hyperkeratotic nodules, some of which are eroded, on the extensor surfaces of the limbs. The most commonly used treatments for this condition are oral antihistamines and topical or systemic steroids. Thalidomide is an effective treatment option in cases of recalcitrant PN; however, its most frequent adverse effect is neurotoxicity, which often results in its discontinuation...

AIMS: Pyoderma, predominantly associated with Staphylococcus pseudintermedius, is a common skin infection of dogs that typically requires long lasting treatments, complicated by increasing antimicrobial resistance. To investigate new treatment strategies, we aimed at establishing a dog model of pyoderma that closely mimics the natural disease. METHODS AND RESULTS: We inoculated six laboratory beagles with a methicillin-susceptible strain of S. pseudintermedius. One mL of e10(7) , 10(8) , 10(9) CFU ml(-1) was topically applied onto clipped and tape stripped area of dog skin, which was then treated with a dermaroller (microneedle size: 500 μm) immediately after administration...

Atopic dermatitis (AD) is a common inflammatory condition of the skin that is usually seen in childhood, but can onset or persist into adulthood. The characteristic distribution and morphology based on age, chronic relapsing course, and pruritus comprise the clinical criteria used in the diagnosis of AD. However, the numerous morphologies ranging from acute, weeping erythematous papules to chronic lichenified plaques, can be simulated by multiple other conditions, including inflammatory, infectious, neoplastic, and photo-dermatoses...

BACKGROUND: Interleukin (IL)-21 is a member of the type I cytokine family and plays a role in the pathogenesis of T helper type 2 allergic diseases. It has been reported that IL-21 expression is upregulated in acute skin lesions in atopic dermatitis (AD) patients; however, little is known about the serum IL-21 levels of AD patients. The aim of this study was to quantify the serum IL-21 levels of AD patients and to evaluate the relationships between the serum IL-21 level and disease severity, laboratory markers, and eruption type in AD patients...

The goals of this German guideline are the improvement of diagnosis and therapy of scabies, the implementation of a coordinated action in outbreaks of scabies, and the control of this infestation in large migration or refugee flows.Sarcoptes scabiei var. hominis is transmitted by direct skin-to-skin contact of sufficient duration. The infectivity of female mites when removed from patients does not exceed 48 hours at room temperature (21°C) and relative humidity of 40-80%. The risk of infection rises proportionally to the number of mites on the skin and is particularly high in crusted scabies...

Autoimmune paraneoplastic and neoplasm-associated skin syndromes are characterized by autoimmune-mediated cutaneous lesions in the presence of a neoplasm. The identification of these syndromes provides information about the underlying tumor, systemic symptoms, and debilitating complications. The recognition of these syndromes is particularly helpful in cases of skin lesions presenting as the first sign of the malignancy, and the underlying malignancy can be treated in a timely manner. Autoimmune paraneoplastic and neoplasm-associated bullous skin syndromes are characterized by blister formation due to an autoimmune response to components of the epidermis or basement membrane in the context of a neoplasm...

Leishmaniasis is a spectrum of disease condition with considerable health impacts, caused by different species of Leishmania. This disease is currently endemic in 98 countries and territories in the world. There are many treatment modalities for cutaneous leishmaniasis. The use of topical terbinafine in the treatment of cutaneous leishmaniasis has recently been considered. Eighty-eight participants more than two years old with proven acute CL by a positive direct smear were randomly allocated to one of the two study arms: first group received meglumine antimoniate (Glucantime) 20 mg/kg/day intramuscular injection (IM) plus a placebo ointment (Mahan Vaseline) for 20 days...
