頭癬是皮癬菌所引起頭皮毛囊和周圍皮膚的感染，好發於青春期前兒童，臨 床表現取決於病原體種類，毛髮侵入和宿主炎症反應的程度。而禿瘡癬（kerion） 是頭癬的一種嚴重的炎症形式表現。本文討論了一名 5 歲 3 個月大的女孩，因左 側的頭皮出現一個軟的腫塊伴隨著黃色的分泌物與疼痛住院治療，氫氧化鉀染色 （KOH）發現黴菌菌絲而頭皮膿樣培養物分離出毛癬菌屬（Trichophyton sp.），經使用 灰黴素（griseofulvin）藥物的治療，成功治療其禿瘡癬。

Tinea capitis is an infection of the scalp hair follicles and the surrounding skin caused by dermatophyte fungi. Tinea capitis predominantly affects prepubertal children. The clinical appearance of tinea capitis is highly variable, depending on the causative organisms, types of hair invasion and degrees of host inflammatory response. This paper covers a 5-year 3-month-old girl with a boggy lump caused by kerion, and reviews the current literature on this disease.
