          Abstract

          We report a case of erythrodermic psoriasis with bullous pemphigoid (BP) in a 68-year-old male. The patient had a history of psoriasis for 35 years and tense, blisterlike lesions for 4 months. He presented with diffuse flushing, infiltrative swelling, and tense blisterlike lesions on his head, trunk, and limbs. This patient was successfully treated by a combination of methotrexate and compound glycyrrhizin. We also discuss the clinical manifestations, histopathological features, and differentiation of erythrodermic psoriasis with BP and present a review of the pertinent literature.

          Modern diagnosis of autoimmune blistering skin diseases.

          The diagnostic gold standard of autoimmune bullous diseases is the detection of autoantibodies in skin or mucous membranes by direct immunofluorescence microscopy of a perilesional biopsy. The molecular characterisation of several target antigens within the last 10 years has, however, fostered the development of sensitive and specific diagnostic tools that allow the serological diagnosis in about 90% of patients. Based on the recombinant immunodominant portions of the target antigens, ELISA systems are commercially available for the detection of circulating antibodies against desmoglein 1, desmoglein 3, envoplakin, BP180, and BP230. Autoantibodies against the soluble ectodomain of BP180 (LAD-1), laminin 332, type VII collagen, and most recently, laminin γ1 can be detected by Western blotting with recombinant or cell-derived forms of these proteins. The definite differentiation between the various immunobullous disorders that comprise about a dozen entities is increasingly important since more diverse treatment options are employed. Exact diagnosis is also pivotal for the prognosis, since some autoimmune bullous diseases may indicate an underlying tumor. Association with a malignancy has been shown in paraneoplastic pemphigus (in 100%) and anti-laminin 332 mucous pemphigoid (in 25%) In pemphigus vulgaris, pemphigus foliaceus, and bullous pemphigoid, autoantibodies to desmoglein 3, desmoglein 1, and BP180, respectively, have been shown to correlate with the disease activity. The detection of serum autoantibodies during the course of the disease may thus be helpful in guiding treatment decisions in these patients. Copyright © 2010 Elsevier B.V. All rights reserved.

            Increased expression of the aryl hydrocarbon receptor in patients with chronic inflammatory skin diseases.

            Polychlorinated biphenyls (PCBs) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) are major environmental pollutants, and their effects on the human body critically depend on the aryl hydrocarbon receptor (AhR). The aim of this study was to evaluate the significance of the AhR and its ligands in chronic inflammatory skin diseases such as atopic dermatitis (AD) and psoriasis. Expression of AhR-related mRNA was increased in lesional skin from patients with AD and psoriasis compared to those of normal skin from healthy controls. The AhR and aryl hydrocarbon receptor nuclear translocator were colocalized in the nuclei of keratinocytes at the lower epidermis of psoriatic lesions, which suggested activation of the AhR pathway. After treatment of normal human epidermal keratinocytes with TCDD or PCBs, IL-6 and IL-8 production were increased. The results of this study suggest that AhR is highly expressed in the acute lesional skin of patients with AD and psoriasis, and the AhR pathway is activated especially in psoriasis. © 2014 John Wiley & Sons A/S.

              Dermoscopy can be useful in differentiating scalp psoriasis from seborrhoeic dermatitis.

              Psoriasis and seborrhoeic dermatitis are common erythematous-squamous dermatoses that may present with scaly erythematous patches on the scalp. Owing to the similar clinicopathological features of these dermatoses, their differentiation poses a diagnostic challenge, particularly when the lesions on the scalp are isolated. To evaluate the usefulness of dermoscopy in the clinical differentiation of scalp psoriasis and seborrhoeic dermatitis. This was a retrospective observational study to evaluate the characteristic dermoscopic features of scalp psoriasis and seborrhoeic dermatitis. The study included a total of 96 patients with lesions; these patients were recruited from two tertiary teaching hospitals in Korea (Pusan National University Hospital and Kyungpook National University Hospital). Among these, 55 patients had scalp psoriasis and 41 patients had seborrhoeic dermatitis. The most significant dermoscopic features of scalp psoriasis were red dots and globules, twisted red loops, and glomerular vessels. In contrast, seborrhoeic dermatitis was characterized by arborizing vessels and atypical red vessels with the absence of red dots and globules. Featureless areas devoid of any particular vascular patterns were also frequently observed in seborrhoeic dermatitis. Dermoscopic findings of red lines and other vascular patterns were not considered useful for differentiation because these were uncommon features in both diseases. Although scales were observed commonly in both diseases, there was no significant difference in the frequency and characteristics of the scales when they were observed using dermoscopy. Our study shows that the investigation of vascular patterns by using dermoscopy can be valuable for the clinical diagnosis and differentiation of scalp psoriasis and seborrhoeic dermatitis. © 2011 The Authors.
