A multivariable model of clinical features for distinguishing sporotrichosis and Mycobacterium marinum cutaneous infection.

To investigate differences in the clinical features of patients with sporotrichosis and cutaneous Mycobacterium marinum infection, and develop a prediction model for the initial identification. A total of 121 patients were selected based on the results from etiological culture. Logistic regression analyses were employed to identify the most valuable variables.

Primary cutaneous infections with non-tuberculous mycobacteria: a report of 6 cases.

Background: The incidence of non-tuberculous mycobacterium infection has shown a gradual increasing trend in recent years, among which cutaneous manifestations as an important aspect. This study aimed to describe the clinical features and microbiological findings in 6 cases of primary cutaneous nontuberculous mycobacterium infection.

Methods: In this retrospective study from June 2021 to June 2022, the clinical data and microbiological results of six cases diagnosed with primary cutaneous non-tuberculous mycobacterium infection in department of dermatology, Hangzhou Third People's Hospital were analyzed.

Extensive erythematous plaques of fungal origin in an overseas student: Cutaneous manifestation of coccidioidomycosis.

We present a case of infection which was contracted during study abroad. This coccidioidomycosis showed atypical manifestations and was diagnosed by a combination of tissue biopsy, metagenomic next-generation sequencing, internal transcribed spacer sequencing and culture. Initial treatment with fluconazole was not effective.

Trichoscopy for early diagnosis and follow-up of pet-related neonatal tinea capitis.

We report infant zigzag hairs as a distinct trichoscopic sign for follow up a case of pet-related newborn tinea capitis due to Microsporum canis. Formation of infant zigzag hairs due to ectothrix M. canis infection may be associated soft neonatal widespread thin hair, which is different from vellus hair and terminal hair.

Bedside Diagnosis for Disseminated Deep Dermatophytosis: a Case Series Study.

Deep cutaneous fungal infections including deep dermatophytosis are responsible for significant morbidity and mortality, especially in immunocompromised patients. Variable and longer turnaround time on tissue culture results delay diagnosis. We sought to seek the fast bedside diagnosis for disseminated deep dermatophytosis by direct microscopy using a blunt scalpel or needle aspiration before biopsy.

Tinea auricularis: a neglected tinea incognito.

Ultraviolet dermoscopy is a rapid and noninvasive diagnosis tool for tinea auricularis caused by Microsporum canis, which facilitated early treatment with systemic antifungals.

Violet colonies of Talaromyces marneffei produce on CHROMagar candida medium.

In the present report, we describe an unusual case of mixed infection of Candida albicans and Talaromyces marneffei in the oral cavity and oropharynx with cutaneous involvement. On the CHROMagar Candida plate, green colonies (identified as C. albicans) and tiny violet colonies (identified as T.

Invasive infection as a presenting complaint of late-diagnosed HIV infection.

A 43-year-old male barber presented with 1 year history of a painful, itchy plaque on the dorsal hand. was recovered from pus of the lesion. Serologic testing for human immunodeficiency virus (HIV) antibody was positive, with a CD4 count of 81 cells per cubic millimeter.

Favus of Scrotum Due to Trichophyton rubrum in Immunocompetent Patients: A Clinical, Mycological and Ultrastructural Study.

Purpose: To characterize the clinical and mycological features of favus of scrotum due to Trichophyton rubrum.

Methods: A single-site prospective study was carried out in an outpatient dermatology clinic. Microscopic examination and fungal culture were done using skin scrapings.

In vitro aminolevulinic acid mediated-antimicrobial photodynamic therapy inactivates growth of Prototheca wickerhamii but does not change antibacterial and antifungal drug susceptibiltity profile.

Background: Antimicrobial photodynamic therapy(aPDT) has been used to treat localized cutaneous fungal infections that have an enhanced antifungal susceptibility profile. The aim of this study was to evaluate the effect of ALA aPDT on both the growth and the antimicrobial and antifungal susceptibility of Prototheca wickerhamii.

Methods: Six isolates of P.

Cutaneous Penicillium marneffei infection in a patient with idiopathic CD4(+) lymphocytopenia.

We describe a case of cutaneous Penicillium marneffei infection in a non-HIV-infected male patient with idiopathic CD4(+) T lymphocytopenia (ICL). The cutaneous lesions were cured after the treatment of itraconazole combined with interleukin-2.

Successful sequential treatment with itraconazole and ALA-PDT for chromoblastomycosis because of Alternaria alternata.

Alternaria alternata is a rare etiology of phaeohyphomycosis in immunocompromised patients, which has never been reported to cause chromoblastomycosis. As far as we know, this is the first chromoblastomycosis case successfully treated with a short course of systemic antifungals and subsequent 5-aminolevulinic acid-photodynamic therapy.
