A Case of Cutaneous Purpureocillium lilacinum
Infection Looking like Psoriasis
Purpureocillium lilacinum is a saprophytic fungus with a ubiquitous environmental distribution, and it can be detected in soil samples and decaying materials worldwide. It has been reported as an emerging pathogen in both immunocompromised and immunocompetent patients, showing various cutaneous presentations. Herein, we report a case of a patient with a localized cutaneous P. lilacinum infection, which resembles the skin lesions of psoriasis. A 72-year-old female was presented with a peripherally spreading, well-demarcated, asymptomatic, scaly, erythematous patch on her forehead for several months. Histopathological examination showed pinkish septated fungal elements and mixed inflammatory and granulomatous infiltrates in the dermis. Furthermore, a fungal culture on potato dextrose agar showed gray, velvety colonies with light yellow background after being subcultured. Phialides with chains of oval conidia were observed on lactophenol cotton blue staining. The ITS region of rRNA gene sequence obtained from the colony was identical to that of Purpureocillium lilacinum. The lesion was resolved with oral itraconazole (200 mg/day) after four months of treatment.
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.
