Dermatosis neglecta (DN) is a frequently underrecognized skin disorder that occurs due to unconscious or conscious neglect of self-cleaning, causing the accumulation of keratin, sweat, sebum, and impurities. It is characterized by asymptomatic yellowish-to-brownish, waxy, adherent papules or plaques with cornflake-like scales that mimic several dermatological conditions. DN awareness is crucial for avoiding unnecessary invasive diagnostic procedures. Its lesions can be removed with some difficulty by ordinary cleansing and efficiently cleared with ethyl or isopropyl alcohol. Individuals with underlying physical or mental disabilities or psychiatric conditions are highly associated with DN. Nevertheless, supportive evidence for the coexistence of DN and psychological conditions is sparse, and most individuals with mental problems usually deny having psychiatric issues. Here, we present a case of DN resembling pemphigus foliaceus on the face with obsessive-compulsive disorder in a 16-years old male. The definitive diagnosis of DN in this patient was confirmed histopathological examination. The lesions completely disappeared after appropriate facial cleansing and psychiatric management. DN may reveal underlying psychiatric disorders in patients.
忽视性皮肤病（DN）是一种常未被充分认识的皮肤疾病，它因无意识或有意识地忽视自我清洁而发生，导致角蛋白、汗液、皮脂和杂质积聚。其特征为无症状的淡黄至褐色、蜡样、附着性丘疹或斑块，伴有类似玉米片样鳞屑，可模仿多种皮肤病状况。认识DN对于避免不必要的侵入性诊断程序至关重要。其皮损通过普通清洁可在一定程度上去除，用乙醇或异丙醇可有效清除。有潜在身体或精神残疾或精神疾病的个体与DN高度相关。然而，支持DN与心理状况共存的证据稀少，且大多数有精神问题的个体通常否认有精神疾病。在此，我们报告一例16岁男性面部类似落叶型天疱疮的DN合并强迫症病例。该患者经组织病理学检查确诊为DN。经适当的面部清洁和精神科治疗后，皮损完全消失。DN可能揭示患者潜在的精神疾病。
