Pitted keratolysis - 窝状角质松解症https://en.wikipedia.org/wiki/Pitted_keratolysis
窝状角质松解症 (Pitted keratolysis) 是一种足部细菌性皮肤感染,伴有明显的异味。感染表现为脚底和脚趾的承重区出现火山口状凹坑。致病菌为棒状杆菌属。足部出汗过多并穿戴封闭鞋类为细菌提供了适宜的繁殖环境。

该病在军队中尤为常见,因为长时间穿着潮湿的鞋或靴且不更换或清洁。诊断主要依靠目视检查并识别特有的气味。治疗通常在患处涂抹抗菌药物,如苯甲酸过氧化物 (benzoyl peroxide)、克林霉素 (clindamycin)、红霉素 (erythromycin)、夫西地酸 (fusidic acid) 或莫匹罗星 (mupirocin)。预防的关键是保持足部干燥。

治疗 - 非处方药
保持双脚和袜子干燥。可使用非处方抗菌软膏,亦可在脚部涂抹洗手液以帮助控制感染。

Pitted Keratolysis 是一个术语,用于描述表面细菌性皮肤感染,主要影响脚底而不是手掌。这种情况通常由久坐球菌和棒状杆菌等细菌引起。它最常见于 21 至 30 岁的人群,大多数人在 20 多岁或 30 多岁时经历过此病。男性的发病风险是女性的四倍,可能与男性更常穿紧身、封闭的鞋子有关,而女性往往保持更好的足部卫生。下面介绍一例 23 岁患者的病例。该患者因脚底不适就诊,主要表现为脚趾周围出现凹陷性皮肤损伤,病程已持续三天。
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 是一种影响足底皮肤表层的细菌性疾病。一名 30 岁男性的足底出现了数个小而破溃的损伤。在更高倍数的显微镜下(×3,500),可清晰看到细菌附着于表面,并呈现特有的分裂模式。
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.
