[Cystic adenoid carcinoma of the larynx. Presentation of a case and review of the literature]. / Carcinoma adenoide quístico de laringe. Presentación de un caso y revisión de la literatura.

We present a case of Adenoid Cystic Carcinoma of the larynx. When we review the literature, we verify the rareness of this carcinoma in this localization. We were made use of this and we realize a exposition of these tumours, with special interest on the clinic study and the treatment carried out in our case.

[Relapsing polychondritis. Apropos of a case]. / Policondritis recidivante. A propósito de un caso.

Relapsing polychondritis is not a very frequent systemic disease. Nevertheless, it has to be borne in mind since very often the first symptoms appear in the sphere of otorhinolaryngology. We are faced with the problem of differential diagnosis in a case which in the beginning seemed to be a neurological pattern. The definitive diagnosis was not established until 15 months after the appearance of the symptoms when, after several outbreaks, the clinical pattern was clearer. As we have to deal with a recurrent and systemic pathology whose diagnosis is eminently clinical, long-term pursuit and valuation are necessary to allow us to know the natural history of the disease as well as the reaction to the treatment.
