Abstract

Most superficial fungal infections of the skin are caused due to dermatophytosis or yeasts. However, it is rare for Cryptococcus species to cause infections. Among the fungal infections by Cryptotoccus species, Cryptococcus (C.) neoformans and C. gattii are the most common pathogenic species. However, other rare infections have been reported. Subcutaneous cryptococcosis due to Naganishia (N.) diffluens (formerly Cryptococcus diffluens) was first reported in Turkey. We present the case of a 53-year-old man who had mild pruritic annular, erythematous, scaly patches with inner small, crusted papules and nodules on both axilla and trunk for 3 months. A potassium hydroxide test on his abdomen scales was positive. Fungal culture, light microscopic findings, and the sequencing of an internal transcribed spacer of rRNA gene confirmed the presence of N. diffluens. As a result we diagnosed the patient with a superficial fungal infection caused by N. diffluens and treated it successfully with oral itraconazole and topical isoconazole.

长谷氏弥散引起浅表真菌感染1例

大多数皮肤表面的真菌感染是由皮肤真菌病或酵母菌引起的。然而，隐球菌引起感染是罕见的。在隐球菌引起的真菌感染中，新形态隐球菌和加蒂隐球菌是最常见的致病种。然而，也有其他罕见感染的报道。由naganishi (N.) diffluens(原隐球菌diffluens)引起的皮下隐球菌病在土耳其首次报道。我们报告一个53岁的男性病例，他在腋窝和躯干有轻度瘙痒的环状红斑鳞状斑块，内部有小的结痂丘疹和结节，持续了3个月。腹部鳞片的氢氧化钾检测呈阳性。真菌培养、光镜观察和rRNA基因内部转录间隔序列的测序证实了N. diffluens的存在。结果，我们诊断患者为由N. diffluens引起的浅表真菌感染，并通过口服伊曲康唑和外用异康唑成功治疗。

期刊介绍： The Journal of mycology and infection (Acronym: JMI, Abbreviation: J Mycol Infect) aims to publish articles of exceptional interests in the field of medical mycology. The journal originally was launched in 1996 as the Korean Journal of Medical Mycology and has reformed into the current state beginning on March of 2018. The contents of the journal should elucidate important microbiological fundamentals and provide qualitative insights to respective clinical aspects. JMI underlines the submission of novel findings and studies in clinical mycology that are enriched by analyses achieved through investigative methods. The journal should be of general interests to the scientific communities at large and should provide medical societies with advanced breadth and depth of mycological expertise. In addition, the journal supplements infectious diseases in adjunct to the field of mycology to address a well-rounded understanding of infectious disorders. The Journal of mycology and infection, which is issued quarterly, in March, June, September and December each year, published in English. The scope of the Journal of mycology and infection includes invited reviews, original articles, case reports, letter to the editor, and images in mycology. The journal is compliant to peer-review/open access and all articles undergo rigorous reviewing processes by our internationally acknowledged team of editorial boards. The articles directed to publication should encompass in-depth materials that employ scholastic values of mycology and various infectious diseases. Articles responding to critical methodology and outcomes which have potential to enhance better understanding of mycology and infectious diseases are also suitable for publication.
