Abstract
Adult tinea capitis, especially kerion, caused by Trichophyton tonsurans is relatively rare in China. Here, we report a case caused by the agent in an old woman with normal immune function. Fungal microscopic examination and culture were positive. The isolate was further identified as Trichophyton tonsurans by internal transcribed spacer (ITS) sequencing. Skin biopsy and histopathological examination suggested diffuse inflammatory cell infiltration in the dermis and subcutaneous tissue. Notably, fungal spores were observed within the dermis by Periodic acid-Schiff (PAS) staining. After eight weeks of treatment with oral griseofulvin and topical luliconazole, the patient's abscess subsided, hair regrowth occurred without scarring, and the mycologic examination returned negative.
期刊介绍：
Mycopathologia is an official journal of the International Union of Microbiological Societies (IUMS). Mycopathologia was founded in 1938 with the mission to ‘diffuse the understanding of fungal diseases in man and animals among mycologists’. Many of the milestones discoveries in the field of medical mycology have been communicated through the pages of this journal. Mycopathologia covers a diverse, interdisciplinary range of topics that is unique in breadth and depth. The journal publishes peer-reviewed, original articles highlighting important developments concerning medically important fungi and fungal diseases. The journal highlights important developments in fungal systematics and taxonomy, laboratory diagnosis of fungal infections, antifungal drugs, clinical presentation and treatment, and epidemiology of fungal diseases globally. Timely opinion articles, mini-reviews, and other communications are usually invited at the discretion of the editorial board. Unique case reports highlighting unprecedented progress in the diagnosis and treatment of fungal infections, are published in every issue of the journal. MycopathologiaIMAGE is another regular feature for a brief clinical report of potential interest to a mixed audience of physicians and laboratory scientists. MycopathologiaGENOME is designed for the rapid publication of new genomes of human and animal pathogenic fungi using a checklist-based, standardized format.
