Coinfección por mycobacterium abscessus y mycobacterium tuberculosis en un paciente con síndrome de cushing exógeno y otras comorbilidades

Mycobacterium abscessus is a fast-growing non-tuberculous mycobacterium that causes lung, skin, disseminated and other infections, mainly in patients with comorbidities. The diagnosis is based on the identification of the mycobacterium by culture media or molecular tests. Treatment with macrolides and amikacin remains the optimal choice, although it depends on the location and severity of the infection; however, resistance genes have been identified in some subspecies that limit antibiotic efficacy. We present the case of a patient with cutaneous coinfection by Mycobacterium abscessus and Mycobacterium tuberculosis, who presented exogenous Cushing syndrome, a predisposing factor for these infections. In addition, hydatidosis and pulmonary aspergillosis were identified. The patient’s anti-tuberculosis treatment was adjusted to manage both mycobacteria, resulting in a favorable evolution.
