Abstract
Background

Post-traumatic Fusarium infection is rare. Arterial occlusive disease, a common vascular disorder in the elderly, often leads to ischemic necrosis of the lower extremities, which in turn increases the likelihood of secondary infections. Those secondary infections can be caused by bacteria, virus, or fungi.

Case report

We present the case of a 64-year-old male patient with a co-infection by Fusarium verticillioides and Proteus vulgaris on nails and foot skin, secondary to senile arterial occlusion on the lower extremities. The skin and nails recovered well after following stent implantation and a combination treatment of itraconazole and a macrolide antibiotic. A retrospective analysis of the literature identified 17 patients with Fusarium infection, all of whom were immunocompetent.

Conclusions

Trauma may be a predisposing cause of Fusarium infection. Combination of oral itraconazole and terbinafine, or amphotericin B and surgical means, are all effective treatments.

Resumen
Antecedentes

Las infecciones postraumáticas por Fusarium son raras. La enfermedad oclusiva arterial, un trastorno vascular frecuente en los ancianos, suele provocar necrosis isquémica de las extremidades inferiores, lo que a su vez aumenta la probabilidad de infecciones secundarias. Dichas infecciones pueden estar causadas por bacterias, virus u hongos.

Caso clínico

Presentamos el caso de un paciente varón de 64 años con una infección por Fusarium verticillioides y Proteus vulgaris en las uñas y piel de los pies, secundaria a una oclusión arterial no traumática en las extremidades inferiores. Tanto la piel como las uñas se recuperaron bien tras la implantación de una endoprótesis vascular, y el tratamiento combinado de itraconazol y un antibiótico macrólido. Un análisis retrospectivo de la literatura arrojó los casos de 17 pacientes con infección por Fusarium, todos ellos inmunocompetentes.

Conclusiones

Los traumatismos pueden ser una causa predisponente de infección por Fusarium. La combinación de itraconazol oral y terbinafina, o anfotericina B y medios quirúrgicos, son tratamientos eficaces.
