[Pseudosarcoma of the larynx]. / Consideraciones sobre el pseudosarcoma de laringe.

Pseudosarcoma of the larynx is a tumor derived as much from connective tissue as from epithelial tissue. There has been much discussion about the malignant nature of the sarcomatous stroma, sometimes considered a benign reaction. However they describe in the literature metastasis cases in which only the sarcomatous element has been demonstrated. We present a case of vocal cord pseudosarcoma in which ten months after performing cordectomy, we can't rule out recurrent disease in spite of the histopathological examination of the cord being negative.

[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.
