[Thyroid actinomycosis: a case report]. / Actinomicosis tiroidea: un nuevo caso.

Actinomycosis is nowadays a not very common festered chronic infection. Cervicofacial actinomycosis is the most frequent clinical form, and it is due in most cases to Actinomyces israelii. Thyroid actinomycosis has been scarcely described in the literature. The lesions, that are characterized to be notably indurated and to contain multiple abscesses that drain to the surface through sinus tracts, frequently simulate other infective clinical entities and often neoplasms, therefore the diagnosis is delayed in the time. From a case of thyroid actinomycosis diagnosed and treated in our service which was initial diagnosed as a thyroid neoplasm, we revise the cases described in the literature and we make a point in the difficulty to arrive to the diagnosis of this entity.

Actinomicosis tiroidea: un nuevo caso / Thyroid actinomycosis: a case report

La actinomicosis es una infección crónica supurada poco común en la actualidad. La actinomicosis cervicofacial es la forma clínica más frecuente, producida en la mayoría de las ocasiones por Acti nomyces israelii. La tiroiditis por actinomices ha sido descrita escaso número de veces en la literatura. Las lesiones que se caracterizan por ser notablemente induradas y contener múltiples abscesos que drenan hacia la superficie por fístulas, frecuentemente simulan otras entidades clínicas infecciosas y con frecuencia neoplásicas con lo que el diagnóstico se retrasa en el tiempo. A partir de un caso de actinomicosis tiroidea diagnosticado y tratado en nuestro servicio, cuyo diagnóstico presuntivo inicial fue de neoplasia tiroidea, revisamos los casos descritos en la literatura, y hacemos hincapié en la dificultad para llegar al diagnóstico de esta entidad (AU)

[Advanced stage laryngeal chondrosarcoma]. / Condrosarcoma laríngeo de alto grado de agresividad.

Chondrosarcoma is a tumor very seldom encountered in the larynx. In this location chondrosarcomas have typical features: slow growing, metastasis rares and scarce tendency to recur. But recurrences occurs at long-term and often can be controlled. We report a case diagnosed and treated in our Hospital which, on the contrary, recurrences presented in a short-term after first surgical removal. Clinical management and treatment of these neoplasms are reviewed.

[Epidermoid of the petrous apex]. / Epidermoide de punta de peñasco.

The AA. report a case of primary cholesteatoma of the petrous apex. These seldom cases show at the beginning trigeminal symptomatology. They are treated through a middle fossa approach. Survey of the literature.
