ABSTRACT
El trago accesorio es una malformación congénita del oído externo que puede asociarse con otras anomalías del primer y segundo arcos branquiales.Presentamos un caso de trago accesorio unilateral, localizado en la región preauricular en una niña de 12 años sin historia familiar de malformacionesdel desarrollo. Describimos el desarrollo embriológico, la clínica y las características histopatológicas del caso, remarcando la posible asociación conotras malformaciones de los arcos braquiales (AU)

We report on two patients with acute lymphoblastic leukemia in induction chemotherapy, who developed a sepsis which led, in both cases, to death following the appearance of neurological symptoms suggesting CNS affectation. Autopsy revealed an angioinvasive disseminated aspergillosis affecting lungs, brain, myocardium, kidneys, thyroid glands in both cases, and endocardium, urinary bladder, lymph nodes, alimentary tract, nasal sinuses in one of the cases. Microbiology study of necropsic tissue showed Aspergillus flavusoryzae and likewise Candida albicans in one case. The latter finding suggest a combined fungal sepsis caused to candida and aspergillus.
