ReferencesLichen Simplex Chronicus (LSC) は、特定の部位が肥厚し、かゆみを伴い、しばしばその上に傷ができる皮膚状態です。これらの部位の色はピンクから濃い茶色まで変化し、経過とともに中心部が明るくなり、周辺が暗くなることもあります。身体のさまざまな部位に広がって隆起として現れる prurigo nodularis (PN) とは異なり、LSC は限られたスポット、あるいは数か所の領域にとどまる傾向があります。LSC は神経皮膚炎と呼ばれることもあり、長期にわたるかゆみを伴う他の症状も含まれます。
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.

ビダール苔癬 (Lichen simplex chronicus) の最もよく見られる部位は、首の側面、頭皮、足首、外陰部、恥骨、陰嚢、そして前腕の伸側です。慢性的な擦過傷の結果、皮膚が肥厚し、色素沈着が過剰になる（＝苔癬化）ことがあります。
この慢性皮膚炎は徐々に進行し、患者は掻くことが習慣化します。ビダール苔癬 (Lichen simplex chronicus) の患者は強い痒みを訴え、同じ部位を制御できずに過度に掻いてしまいます。
○ 治療 ― OTC医薬品
石鹸で患部を洗っても効果がなく、かえって悪化することがあります。
市販のステロイド軟膏の効果が薄い場合があります。改善には1週間以上の継続的な塗布が必要です。
#Hydrocortisone ointment
OTCの抗ヒスタミン薬。セチリジンまたはレボセチリジンはフェキソフェナジンよりも効果的ですが、眠気を引き起こします。
