Development of nevus spilus-like lentigines in zones previously affected by plaques of psoriasis has been described. Most cases have appeared following phototherapy; then it has been suggested that the mechanism involved could be an abnormal reaction to UV light. However, cases of multiple lentigines arising within resolving psoriatic in patients who had not received phototherapy or photochemotherapy have been described as a result of possible post-inflammatory hyperpigmentation. We report the case of patient who developed nevus spilus-like lentigines following therapy with topical calcipotriol on psoriatic plaques. We consider that the mechanism of production of lentigines is an unusual form of postinflammatory hyperpigmentation.
曾有报道称，在先前受银屑病斑块影响的区域出现了雀斑样痣样色素沉着斑。大多数病例出现在光疗之后；因此有人提出，其中涉及的机制可能是对紫外线的异常反应。然而，在未接受光疗或光化学疗法的银屑病患者病情缓解过程中出现多发性色素沉着斑的病例，被认为可能是炎症后色素沉着过度所致。我们报告了1例患者，其在使用外用卡泊三醇治疗银屑病斑块后出现了雀斑样痣样色素沉着斑。我们认为，色素沉着斑的产生机制是一种不寻常的炎症后色素沉着过度形式。
