Surg Infect (Larchmt) 2019 Sep 8;20(6):492-498. Epub 2019 May 8.

2School of Medicine, National Yang-Ming University, Taipei, Taiwan, Republic of China.

The incidence of non-tuberculous mycobacterial (NTM) infections of the skin, soft tissue, and musculoskeletal system (SSTI) has increased over the past two decades, however, relatively few studies have documented the reasons for the reported increase. Specifically, no standardized treatment protocols have been adopted, therefore, clinical prognosis of the patients with NTM SSTI has thus far remained uncertain. In our study, we sought to identify risk factors for treatment failure in southern Taiwan. Read More

Cutaneous Mycobacterial Infections.

Clin Microbiol Rev 2018 01 14;32(1). Epub 2018 Nov 14.

Servicio de Dermatología y Departamento de Micología, Hospital General de México, Mexico City, Mexico.

Humans encounter mycobacterial species due to their ubiquity in different environmental niches. In many individuals, pathogenic mycobacterial species may breach our first-line barrier defenses of the innate immune system and modulate the activation of phagocytes to cause disease of the respiratory tract or the skin and soft tissues, sometimes resulting in disseminated infection. Cutaneous mycobacterial infections may cause a wide range of clinical manifestations, which are divided into four main disease categories: (i) cutaneous manifestations of infection, (ii) Buruli ulcer caused by and other related slowly growing mycobacteria, (iii) leprosy caused by and , and (iv) cutaneous infections caused by rapidly growing mycobacteria.
