Journal Title: Türkderm - Deri Hastalıkları ve Frengi Arşivi - Year 2019, Vol 53, Issue 3
Abstract
Background and Design: Erythrasma is a superficial, local, mild and chronic skin infection caused by Corynebacterium minutissimum. Interdigital variant is the most frequent site for bacterial infection of the feet and it is the most common form of erythrasma. It frequently involves moist and closed intertriginous areas together with fissure or squama. The purpose of this study is to research the frequency of erythrasma in patients who refer with interdigital maceration and who are generally considered to have tinea pedis. Materials and Methods: The study was conducted between 15 January 2018 and 15 April 2018. A total of 116 patients who referred with the complaint of interdigital maceration were included in the study. A questionnaire form including demographic information were completed for all patients. All patients were examined with Wood lamp, smears taken were stained with Gram staining and examined under direct microscopy with 20% potassium hydroxide. Results: Of all the 116 patients with interdigital maceration, 97 (83.6%) were diagnosed with erythrasma. Of these 97 erythrasma patients, 66 (68%) were male, 31 (32%) were female and the average age was 48.27±16.29 (minimum age: 20, maximum age: 86 years). Fifteen patients had only Gram staining positive, while 7 patients had only Wood examination positive. Seventy-five patients had both Wood examination and Gram staining positive. Fungal infection was found in direct potassium hydroxide examination of 65 (67%) patients. Conclusion: Erythrasma is frequently seen in patients with maceration. It is important to use Wood light examination and Gram staining together to increase diagnostic accuracy. In addition, it should be kept in mind that erythrasma can be seen with candida and dermatophyte infection when interdigital areas are affected.
