ReferencesLichen Simplex Chronicus (LSC) 是一种皮肤状况，表现为某些部位皮肤增厚并伴有强烈瘙痒，常在表面出现划痕。这些部位的颜色可从粉红色到深棕色不等，随着病程延长，中心可能变浅而边缘颜色加深。与另一种以遍布全身的结节性瘙痒为特征的 prurigo nodularis (PN) 不同，LSC 通常局限于特定部位或少数区域。虽然 LSC 有时被称为神经性皮炎，但它仍属于长期持续的瘙痒性皮肤病之一。
LSC is a localized skin disorder clinically characterized by lichenified plaques of skin often accompanied by overlying excoriations. These plaques can become discoloured, with varying shades of erythema ranging from pink to dark brown. Over a longer course, it may transform into a hypopigmented plaque with a darker border. They are localized to specific areas of the body as one or a few plaques. This is in contrast to prurigo nodularis (PN), another chronic pruritic condition, which is frequently more broadly distributed across multiple regions of the body as nodules. While LSC may sometimes be referred to as a neurodermatitis, which encompasses other chronic itchy conditions.

Lichen simplex chronicus is defined as a common form of chronic neurodermatitis that presents as dry, patchy areas of skin that are scaly and thick. The hypertrophic epidermis generally seen is typically the result of habitual scratching or rubbing of a specific area of the skin.

这种慢性皮肤疾病呈逐渐进展。患者往往形成抓挠的习惯。患有慢性单纯性苔藓 (lichen simplex chronicus) 的患者会感到瘙痒，进而难以控制地反复抓挠同一部位。
○ 治疗 - 非处方药
仅用肥皂清洗患处并无帮助，反而可能加重症状。
非处方的类固醇软膏效力有限，通常需要连续使用1周或更长时间才能见效。
#Hydrocortisone ointment
非处方抗组胺药。西替利嗪或左西替利嗪比非索非那定更有效，但会使您昏昏欲睡。
#Cetirizine [Zytec]
#LevoCetirizine [Xyzal]
