患儿女,4岁。体重19kg,下颌皮肤出现米粒大小红斑14天,其母亲使用橄榄油润肤霜(具体品牌不详)涂抹患处,红斑面积逐渐扩大,偶瘙痒,有宠物猫接触史。

【一般资料】

患儿女,4岁。体重19kg,

【现病史】

下颌皮肤出现米粒大小红斑14天,其母亲使用橄榄油润肤霜(具体品牌不详)涂抹患处,红斑面积逐渐扩大,偶瘙痒,有宠物猫接触史。

【体格检查】

皮肤科情况:下颌可见鸽蛋大小红斑,中央颜色略浅,皮损边界清楚,未见明显鳞屑、脓疱(图1)。偏振光皮肤镜(江苏捷达)下皮损背景颜色偏粉红,未见鳞屑或脓疱;部分毳毛明显比正常毳毛短,且呈不规则卷曲、弯折(图2)。





【辅助检查】

用透明胶带粘取异常毳毛,滴加荧光染料(伊文思蓝+钙荧光白,江苏莱芙特敏),立即置于荧光显微镜下,调整光源模式为紫外光与普通光双光源重叠,可见病变毳毛弯折,毛根部被大量发出亮绿色荧光的菌丝和孢子包绕,部分菌丝游离向周围伸展(图3)。扫描电镜下可见大量菌丝及孢子形成的菌鞘(图4)。将病毛接种于含氯霉素及放线菌酮的沙堡弱培养基(SDA)上,14天后生长出白色绒毛状菌落(图5),菌落小培养标本经荧光染色后可见亮绿色胞壁和分隔的纺锤状大分生孢子(图6)。提取菌落DNA,经ITS1/4引物做PCR扩增,产物测序后登陆GenBank比对,与太田节皮菌(犬小孢子菌有性期)同源性99%,登记号:KC833517.1。

【初步诊断

诊断为犬小孢子菌所致面癣伴毳毛癣,

【治疗经过】

予口服伊曲康唑胶囊100mg,1次/d,每日用2%酮康唑洗剂清洁面部后局部外用萘替芬酮康唑软膏。嘱患儿远离宠物猫,宠物猫同时治疗。患儿口服伊曲康唑14天,外用药物1个月后随访,面部红斑消退(图7),皮肤镜下背景颜色恢复正常,未见明显鳞屑,毳毛恢复正常状态(图8),真菌镜检(-),遂停药观察。治疗前后肝肾功能均正常。

【讨论】

毳毛又称汗毛,细软无髓质,透明或半透明,直径不超过30μm,主要见于面部、四肢和躯干部。毳毛癣由Eby等于1987年首次提出,临床表现不典型,通常炎症反应较重,真菌聚集在毳毛表面或毛根部,若不及时治疗,易导致毛囊性脓疱、感染性肉芽肿等症状。犬小孢子菌属亲动物性真菌,多由直接或间接接触患病的猫、狗、兔等而感染。菌体分泌的角质蛋白酶、蛋白酶、脂肪酶使其黏附并入侵皮肤、毛发、甲的角质层而致病,我国约80%儿童头癣为该菌引起。目前报道的毳毛癣病原菌主要为石膏样小孢子菌、犬小孢子菌、须癣毛癣菌、紫色毛癣菌以及红色毛癣菌,致病机理与头癣类似,因此提倡系统服用抗真菌药物治疗,口服伊曲康唑、氟康唑、特比萘芬均安全有效。本病患儿皮损炎症较轻,且无明显脓疱、鳞屑,易被误诊为钱币状湿疹,且毳毛太过微小,仅凭肉眼判断毳毛病变很难做到。Gómez-Moyano等在皮肤镜下发现病变毳毛呈半透明状和螺旋状。笔者首次在皮肤镜下发现皮损区域内毳毛出现变短、弯折和不规则卷曲的情况,与头癣的病发受累情况相似,提示毳毛受累,在皮肤镜指导下,直接取受累毳毛,通过真菌荧光染色、扫描电镜和分子鉴定确认毳毛受累情况和病原菌,确保发现和鉴定病原菌。随访过程时利用皮肤镜观察毳毛生长情况,有利于判断病情恢复程度,确定疗程和停药时机。
