ABSTRACT

O pioderma gangrenoso é uma dermatose inflamatória crônica, que se associa a doenças sistêmicas como a artrite reumatoide. É mais comum em adultos e pode se apresentar com quatro formas clínicas, todas levando à ulceração da pele acometida. Seu diagnóstico é clínico e de exclusão. O tratamento deve ser realizado com cuidados locais e terapia sistêmica.


Pyoderma gangrenosum is a chronic inflammatory dermatosis, which is associated with non-infectious systemic diseases such as rheumatoid arthritis and inflammatory bowel disease. It is more common in adults and may present with four distinct clinical forms, all leading to ulceration of the skin affected. Its diagnosis is clinical and demands exclusion of other causes. Treatment should be performed with local care and systemic therapy.

ABSTRACT

Nails are considered epidermal appendages, and as such, are commonly affected in patients with psoriasis, 80% of whom are likely to develop nail psoriasis as a result of their condition. Two patterns of nail disorders have been shown to be caused by psoriasis. Nail matrix involvement can result in features such as leukonychia, pitting (punctures or cupuliform depressions), red spots in the lunula and crumbling. Nail bed involvement, on the other hand, can cause onycholysis, salmon or oil-drop patches, subungual hyperkeratosis and splinter hemorrhages. Nail disease causes aesthetic and functional impairment, and is indicative of more severe forms of psoriasis as well as of joint involvement. The treatment for nail psoriasis involves behavioral interventions, topical medications, or systemic therapy in case of extensive skin or joint involvement. This article presents a review of the main features of nail psoriasis, its clinical presentation, diagnostic and assessment methods, clinical repercussions, and of its available treatment options.

ABSTRACT

JUSTIFICATIVA E OBJETIVOS: A vasculite urticariforme (VU) corresponde entre 5% a 10% das urticárias crônicas, devendo-se distinguir suas lesões daquelas da urticária crônica idiopática, que é a forma mais comum. Apesar de comumente ser de origem idiopática, pode ocorrer em associação com doenças autoimunes, reação a drogas, infecções ou malignidade, podendo ocorrer de forma sistêmica ou limitada à pele. O diagnóstico de VU deve ser considerado na presença de urticária persistente com achados clínicos e sorológicos sugestivos, ou evidência de doença sistêmica. O objetivo deste estudo foi mostrar um caso raro de acometimento renal da forma normocomplementêmica da vasculite urticariforme. RELATO DO CASO: Paciente do sexo masculino, 38 anos, previamente hígido, que apresentava lesões papulares eritêmato-violáceas extensas. Exames laboratoriais iniciais não apresentavam alterações significativas; exame qualitativo de urina demonstrava alteração progressiva da função renal e níveis nefróticos de proteinúria. A imunofluorescência renal foi negativa. Sorologias foram todas negativas e exames imunológicos não reagentes. Dosagemde complemento sérico (C3 e C4) foi normal. Realizou-se pulsoterapia com corticoide endovenoso e seguimento com corticoide oral, obtendo-se boa resposta clínica. A lesão cutânea apresentou regressão espontânea sem o uso de medicação tópica. CONCLUSÃO: O diagnóstico da doença sistêmica a partir de uma alteração cutânea salienta a importância da investigação adicional das lesões vasculares de pele.


BACKGROUND AND OBJECTIVES: Urticarial vasculitis (UV) corresponds between 5% to 10% of chronic urticaria, and their lesions must be distinguished from those of chronic idiopathic urticaria, which is more common. Although commonly idiopathic, it may occur associated with autoimmune diseases, drug reactions, infections or malignancy, which may occur in asystemic presentation or limited to the skin. The diagnosis of UV should be considered in the presence of persistent urticaria with suggestive clinical and serologic findings, or evidence of systemic disease. The case report illustrates a rare renal complication of the normocomplementemic form of urtical vasculitis. CASE REPORT: Male patient, 38 years, previously healthy, who presented extensive erythematous-violaceous papules. Initial laboratory tests showed no significant changes, qualitative urine test showed progressive impairment of renal function and levels of nephrotic proteinuria. Renal immunofluorescence was negative. Serology and immunological tests were all negative. Dosage of serum complement (C3 and C4) was normal. We performed intravenous steroid pulse therapy and follow up with oral steroids,obtaining good clinical response. The skin lesions regressed spontaneously without the use of topical medication. CONCLUSION: The diagnosis of systemic disease from a skin change emphasizes the importance of further investigation of cutaneous vascular lesions.
