Excoriation (skin picking) disorder is included in the DSM-5 in the obsessive compulsive and related disorders category. It is defined as the recurrent urge to touch, scratch, scrape, scrub, rub, squeeze, bite or dig in the skin, leading to skin lesions. It is a rare disorder (1.4-5.4% of the population) and occurs mainly in women.
this article reports the case of a 31-year-old female patient, initially assessed by dermatology and orthopaedics for the presence of infected ulcerated lesions on her lower limbs, with other superficial lesions from scratching on her chest, arms, forearms, back and head. The patient also reported symptoms of anxiety, so was assessed by consultation-liaison psychiatry.
skin picking, normal behaviour in mammals, becomes pathological from a psychiatric point of view when it is repetitive and persistent, as in the case of excoriation disorder. In view of the reported relationship with the obsessive-compulsive spectrum, use of selective serotonin reuptake inhibitors and cognitive behavioural therapy are recommended.
搔抓（皮肤抠挖）障碍被纳入《精神疾病诊断与统计手册》第5版的强迫症及相关障碍类别中。它被定义为反复出现的触摸、抓挠、刮擦、擦洗、揉搓、挤压、咬或抠皮肤的冲动，导致皮肤损伤。这是一种罕见的障碍（占人口的1.4 - 5.4%），主要发生在女性身上。
本文报告了一名31岁女性患者的病例，该患者最初因下肢存在感染性溃疡病变以及胸部、手臂、前臂、背部和头部因搔抓出现的其他浅表病变而接受皮肤科和骨科评估。患者还报告了焦虑症状，因此接受了会诊联络精神病学的评估。
搔抓在哺乳动物中是正常行为，但从精神病学角度来看，当它像搔抓障碍那样反复且持续时就会成为病态。鉴于其与强迫症谱系的报道关系，建议使用选择性5-羟色胺再摄取抑制剂和认知行为疗法。
