Pitted keratolysis is a bacterial skin infection of the foot with odor. The infection is characterized by craterlike pits on the sole of the feet and toes, particularly weight bearing areas.
Pitted Keratolysis 是一個術語,用於描述表面細菌性皮膚感染,主要影響腳底而不是手掌。這種情況通常由久坐球菌、棒狀桿菌等細菌引起,最常見於 21 至 30 歲的人群,大多數人在 20 多歲或 30 多歲時曾經歷過。男性罹患此疾病的風險是女性的四倍,可能與較常穿緊身、封閉的鞋子有關;相較之下,女性往往較注重足部衛生。以下介紹一名 23 歲患者的病例:他因腳底(主要是腳趾周圍)出現凹陷性皮膚損傷而就診,該損傷已持續三天。 Pitted Keratolysis is a descriptive title for a superficial bacterial skin infection that affects the soles of the foot, less frequently, the palms confined to the stratum corneum. The etiology is often attributes due to Kytococcus sedentarius and Corynebacterium species bacteria. Pitted keratolysis is most common in the age group of 21 to 30 years, with a majority of affected patients in their 1st to 4th decade of life. Males are at 4 times higher risk of being susceptible to this condition, presumably, due to frequent use of occlusive footwear, whereas females maintain better foot hygiene. We present a case of a 23-year-old medical intern who presented to our hospital with complaints of pitted skin lesion over base of foot, predominantly over toes for past 3 days.
Pitted keratolysis 是一種影響腳底外層皮膚的疾病,由細菌引起。一名 30 歲男子的腳底出現了幾處小而破裂的損傷。在更高的放大倍率(×3,500)下,細菌在表面清晰可見,呈現出特定的分裂模式。 Pitted keratolysis is a skin disorder that affects the stratum corneum of the plantar surface and is caused by Gram-positive bacteria. A 30-year-old male presented with small punched-out lesions on the plantar surface. A superficial shaving was carried out for scanning electron microscopy. Hypokeratosis was noted on the plantar skin and in the acrosyringium, where the normal elimination of corneocytes was not seen. At higher magnification (x 3,500) bacteria were easily found on the surface and the described transversal bacterial septation was observed.
此病相當常見,尤其在軍隊中,因長時間穿著潮濕的鞋或靴且未及時更換或清潔。凹陷性角化松解症的診斷主要靠目視檢查並辨識特有的氣味。治療上需在皮膚上使用抗生素,例如 Benzoyl peroxide (過氧化苯甲醯)、Clindamycin (克林黴素)、Erythromycin (紅黴素)、Fusidic acid (夫西地酸) 或 Mupirocin (莫匹羅星)。預防的重點是保持足部乾燥。
○ 治療 - 非處方藥
保持雙腳與襪子乾燥。可使用非處方抗生素軟膏,並在腳部塗抹含酒精的洗手液以協助消毒。
