PASE (Psoriatic Arthritis Screening and Evaluation) was developed in the English language to screen for inflammatory arthritis among patients with psoriasis. It is 15 item self administered questionnaire with a score from 15 to 75. A higher score indicates a greater risk for inflammatory joint disease. The purpose of this study was to translate, ad...

Prurigo pigmentosa (PP) is a rare inflammatory disease of the skin of uncertain etiology first reported in Japan. It is typified by recurrent eruptions of itching urticarial macules, papules, vesicopapules, and plaques with a reticular arrangement that quickly resolve leaving a net-like pigmentation. The disease presents specific histopathological...

Background: Among the chronic leg ulcers, venous ulcers are the most common and constitute a major burden to public health. Despite all technology available, some patients do not respond to established treatments. In our study, carboxymethylcellulose was tested in the treatment of refractory chronic venous ulcers. Objective: To evaluate the effi...

To determine the prevalence of psoriatic arthritis (PsA) in a large cohort of Brazilian patients with psoriasis (PsO) being seen at dermatology centers. A multicenter study was conducted in 4 university dermatology clinics. In each center, consecutive patients with confirmed diagnoses of PsO were evaluated by a rheumatologist. Individuals were clas...

A dermatite seborreica (DS) e uma doenca cronica, eritematoescamativa de etiopatogenia ainda desconhecida. A relacao entre a DS e os antigenos leucocitarios humanos (HLA) nao esta estabelecida. Foi desenvolvido estudo observacional, caso-controle, comparando a expressao dos genes do HLA em 55 pacientes com DS e 97 voluntarios saudaveis pareados em...

Background Geographic tongue (GT) is the most frequent oral lesion in psoriatic patients (PP), and genetic involvement in these conditions has been described. The association of psoriasis with GT is still not clear, and the study of human leucocyte antigen (HLA) may help clarify this relation.Objective The aim of this study was to investigate the a...

Atopic dermatitis and seborrheic dermatitis are multifactorial dermatitides that are known collectively as endogenous dermatitis. Both conditions can affect the face, but they have clinical, epidemiological, and physiopathological peculiarities that distinguish them from each other. These two diseases are very common all around the world. Atopic de...

Linear IgA dermatosis has been increasingly associated with inflammatory bowel diseases, particularly ulcerative colitis. A 13-year-old male patient with an 11-month history of ulcerative colitis developed vesicles, pustules and erosions on the skin of the face, trunk and buttocks and in the oral mucosa. The work-up revealed a neutrophil-rich sub-e...

Background: Infections are known to trigger and exacerbate psoriasis. Although oral candidiasis is often clinically diagnosed, it is not always confirmed by laboratory tests such as oral cytopathology. Objectives: The aims of this study were to determine the prevalence of oral candidiasis in patients with psoriasis through clinical and cytopatho...

Background: Geographic stomatitis is an uncommon oral lesion that presents similar clinical, histopathological and genetic features as those of psoriasis. These findings suggest that this lesion may actually represent an oral manifestation of psoriasis. We report one case of geographic stomatitis and discuss a possible connection between this cond...

Seborrheic dermatitis is a chronic relapsing erythematous scaly skin disease, the prevalence of which is around 1 to 3% of the general population in the United States. It has two incidence peaks, the first in the first three months of life and the second beginning at puberty and reaching its apex at 40 to 60 years of age. The prevalence of seborrhe...

Glomeruloid hemangioma is characterized by coiled capillary vessels contained within enlarged vascular spaces displaying an architecture that resembles renal glomeruli. The condition is strongly associated with POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy and Skin changes). The present paper reports on two cas...

Bone marrow-derived cell therapy has been investigated in patients with severe liver disease. To assess the feasibility, safety and cell kinetics of autologous bone marrow-derived mononuclear cells (BMMCs) infusion in cirrhotic patients. BMMCs were isolated from autologous bone marrow and 10% of the cells were labelled with (99m)Tc-SnCl₂. Whole bod...

O perineurioma esclerosante é uma neoplasia benigna rara,constituída exclusivamente por células com diferenciação perineural, dispersas em meio a estroma fibroso denso. Acomete preferencialmente a pele dos quirodáctilos e das regiões palmares e se apresenta como pápula ou nódulo firme, normocrômico e assintomático. Apresentamos um caso de perineuri...

Sclerosing perineurioma is a rare benign neoplasm composed exclusively of perineural differentiation cells spread in a dense fibrous stroma. It affects primarily the skin of fingers and that of the palm of the hands. It appears as a hard papule or nodule, normochromic and asymptomatic. A case of sclerosing perineurioma in the left palm of a 16-year...
