區分頭瘡:濕疹掉皮屑 頭癬脫髮似圓餅

頭皮起疹,流膿結痂,到底是頭瘡,抑或是「手尾長」的濕疹及頭癬?皮膚科專科醫生馮偉傑表示,頭瘡、濕疹及頭癬,三者有明顯分別。他指出,頭部濕疹患者會掉皮屑,肩膀不時出現頭皮屑,相反頭瘡患者不會有此情况。至於如何區分頭癬與頭瘡,他指出,可由脫髮範圍來區分。他解釋,頭瘡為油脂腺閉窒引致,面積較細小,脫髮範圍不會集中,有別頭癬,「頭瘡面積細,脫髮時也是個別的數條頭髮,但頭癬的脫髮範圍集中,似是一個圓餅」。

嚴重頭瘡可致毛囊死亡

馮偉傑表示,頭瘡不是大病,西醫臨牀上多會處方抗生素藥膏,或處方洗頭水,減少頭油分泌,有助減少頭瘡的形成。但部分患者的頭瘡情况嚴重,因傷口不斷復發,致毛囊死亡,出現脫髮;屬於囊腫型頭瘡患者,需口服抗生素及維他命A酸,處理頭油分泌過度旺盛的問題。
