Dermatosis neglecta

Abstract

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.

Dermoscopy in terra firma‐forme dermatosis and dermatosis neglecta

“…The dermoscopic findings detected in our TFFD cases are in line with data reported in previous eight cases, thus confirming the reliability of dermoscopy in assisting the diagnosis of this condition by showing large polygonal plate‐like brown scales arranged in a mosaic pattern. Moving to DN, two prior dermoscopic reports have been described in the literature, both of them revealing a pattern similar to that of TFFD . However, the diagnosis of DN in such patients was not confirmed by a positive soap water swab test, thereby not ruling out the diagnosis of TFFD.…”

Dermatose Neglecta - Afecção de Difícil Suspeição Diagnóstica

“…À dermatoscopia, evidencia-se ausência de estruturas comuns a outros diagnósticos diferenciais, além de evidenciar coloração característica acastanhada sugerindo acúmulo de queratina na superfície. 9 O estudo anatomopatológico geralmente não é necessário, mas quando realizado mostra hiperqueratose ortoceratótica, papilomatose e acantose leve sem um infiltrado inflamatório evidente. 4 Vigorosa fricção com gaze embebida em álcool ou sabão e água resulta em resolução completa do quadro.…”

“…3 Casos mais resistentes com placas verrucosas podem demandar uso de agentes ceratolíticos e emolientes para facilitar sua remoção. 9 O relato de higiene "normal" -banhos diários -não exclui a possibilidade de ter dermatose neglecta, bastando que negligencie uma determinada região ao fazer a sua higiene. Esta afecção deve fazer parte dos diagnósticos diferenciais de lesões hiperpigmentadas localizadas, principalmente em paciente com quadros crônicos caracterizados por dor e imobilidade.…”

Dermatosis neglecta of the scalp complicated with alopecia areata

“…Dermatosis neglecta is a dirt-associated condition caused by the failure of washing. [ 1 ] The lesion is usually distributed on the trunk, neck, or shoulders,[ 2 ] showing a hyperpigmented, verrucous surface with adherent scales or crust. Herein, we introduce a case of dermatosis neglecta complicated with alopecia areata on the scalp.…”
