【摘要】：目的分析白色線狀苔蘚(lichen striatus albus,LSA)的臨床及皮膚CT特點(diǎn)。方法回顧性分析LSA患者的皮膚CT、組織病理及臨床資料。結(jié)果 58例患者中,男26例,女32例,年齡1~33歲,平均6.97±5.36歲。皮損位于下肢25例,上肢15例,面頸部8例,軀干7例,手背3例。臨床上LSA表現(xiàn)為單側(cè)沿Blaschko線分布的色素減退斑。皮膚CT下LSA表現(xiàn)為輕度角化過度,表皮水腫,基底層黑色素減少,局部基底層液化。真皮乳頭及淺層可見少至中等量單個(gè)核細(xì)胞,散在分布少量形態(tài)不規(guī)則的高反光大細(xì)胞,為噬黑素細(xì)胞。結(jié)論兒童四肢突然出現(xiàn)的單側(cè)沿Blaschko線分布的色素減退斑,結(jié)合皮膚CT顯示的局部基底細(xì)胞液化,炎癥背景下可見形態(tài)不規(guī)則的高反光大細(xì)胞,高度提示LSA的診斷。
[Abstract]:Objective to analyze the clinical and skin CT features of (lichen striatus albus,LSA. Methods the histopathological and clinical data of skin CT, in patients with LSA were analyzed retrospectively. Results among the 58 patients, there were 26 males and 32 females, aged 1 to 33 years (mean 6.97 鹵5.36 years). The lesions were located in 25 cases of lower limbs, 15 cases of upper limbs, 8 cases of face and neck, 7 cases of trunk and 3 cases of back of hand. The clinical manifestation of LSA was hypopigmentation along the line of Blaschko. Under CT, LSA showed mild keratosis, epidermal edema, decreased melanin in the basal layer and liquefaction of the local basal layer. The dermal papilla and the superficial layer can be seen as few to moderate mononuclear cells, scattered in a small number of irregular high light reflecting large cells, which are melanophagocytes. Conclusion the pigmented hypochromatic spots along the Blaschko line and the liquefaction of the local basal cells displayed by CT in the extremities of children were suddenly appeared in the extremities of the children. The abnormal hyperreflective large cells could be seen in the inflammatory background, which was highly helpful for the diagnosis of LSA.
