Dermatosis neglecta

Dermatosis neglecta is the name of a skin condition characterized by papules and polygonal plaques, which are sometimes warty, brownish and hyperpigmented, adherent and symmetric, though removable with ethyl or isopropyl alcohol. It occurs due to inadequate skin cleansing causing accumulation of sebum, sweat, keratin and impurities. Its occurrence, though little reported, is frequent. The main differential diagnosis is the Terra fi rma-forme dermatosis. The treatment is simple, with exfoliation, moisturizing and even rubbing of alcohol. Causes of negligence on the patient’s side, which can range from hygiene carelessness to psychiatric disorders, local hypersensitivity, limbs negligence or motor paralysis, should be investigated. We illustrate the case of dermatosis neglecta in a 45-years old patient admitted with pulmonary sepsis.

Pneumonite de hipersensibilidade / Hypersensitivity pneumonitis

Pneumonite de hipersensibilidade (PH) ou alveolite alérgica extrínseca é uma reação inflamatória imune que ocorre em indivíduos suscetíveis, devido à inalação de antígenos orgânicos e/ou inorgânicos. Esta patologia deve ser suspeitada quando houver relato de exposição a poeiras orgânicas. Relata-se um caso de PH em paciente masculino de 33 anos, com história de dispnéia, tosse, emagrecimento e febre, apresentando regressão da doença após interrupção da exposição a antígenos de aves. O diagnóstico geralmente é baseado na história e no exame clínico, confirmado pelo aparecimento de lesões típicas nos exames de imagem e pela biópsia pulmonar. O tratamento adequado resulta em melhora dos sintomas, do quadro imagético e do padrão espirométrico. O afastamento do agente causador usualmente regride a doença e a corticoterapia pode ser eficaz em reprimir a resposta inflamatória (AU)

Hypersensitivity pneumonitis (HP), or extrinsic allergic alveolitis, is an immune inflammatory reaction affecting susceptible individuals due to inhalation of organic and/or inorganic antigens. This pathology must be suspected if there is report of exposure to organic dusts. In this article a case of PH is reported in a 33-year-old male with history of dyspnea, coughing, weight loss, and fever, with regression of the disease after discontinuation of exposure to bird antigens. The diagnosis is usually based on history and clinical examination, confirmed by the appearance of typical lesions in imaging and pulmonary biopsy. Proper treatment results in improvement of symptoms, imaging picture, and spirometric pattern. The removal of the causal agent usually determines regression of the disease, and corticoid therapy may be effective in repressing the inflammatory response (AU)
