Pustulosis exantemática generalizada aguda asociada a Mycoplasma pneumoniae: reporte de un caso / Acute generalized exanthematous pustulosis associated with Mycoplasma pneumoniae infection: a case report

Acute generalized exanthematous pustulosis is an uncommon skin eruption, characterized by fever and the rapid onset of disseminated, non-follicular, sterile pustules, over an erythematous skin background. It is usually classified as a severe cutaneous adverse drug reaction, whose most relevant triggers are antibiotics and anticonvulsants. However, viral and bacterial infections have also rarely been associated with this dermatosis. We report the case of a patient, who developed lesions of acute generalized exanthematous pustulosis as an extrapulmonary manifestation of Mycoplasma pneumoniae infection.

Tuberculosis en patrón esporotricoide: una presentación inusual de tuberculosis cutánea en un paciente inmunocompetente / Sporotrichoid-like tuberculosis: an unusual presentation of cutaneous tuberculosis in an immunocompetent patient

Tuberculosis remains a major global health problem. Cutaneous involvement is a rare manifestation of tuberculosis infection. Sporotrichoid clinical pattern consists of a linear arrangement of nodules along the lymphatic vessels. It is often seen in sporotrichosis. Few cases have been reported of cutaneous tuberculosis presenting as a sporotrichoid clinical pattern. We describe a 84-year-old female with ulcerative nodules on upper extremity caused by Mycobacterium tuberculosis, emphasizing the importance of considering cutaneous tuberculosis in the differential diagnosis of sporotrichoid lesions.

En la actualidad, la tuberculosis sigue siendo un problema de salud pública en el mundo. El compromiso cutáneo es una manifestación poco frecuente de la infección por Mycobacterium tuberculosis. El patrón esporotricoide se refiere a la disposición lineal de los nódulos cutáneos siguiendo el trayecto de los vasos linfáticos, forma de presentación característica de la esporotricosis, de ahí su nombre. Muy pocos casos han sido reportados sobre tuberculosis cutánea con patrón esporotricoide. Se presenta el caso clínico de una mujer de 84 años con nódulos ulcerativos de disposición lineal en miembro superior causados por Mycobacterium tuberculosis, destacando la importancia de incluir a la tuberculosis cutánea en el diagnóstico diferencial de lesiones con patrón esporotricoide.
