[The adenoid cystic carcinoma]. / Carcinoma adenoide quístico de CAE.

The adenoid cystic carcinoma arising in the external auditory canal is a rare tumor, as other malignant neoplasias of the EAC and middle ear. The early diagnosis of these malignant tumors of the ear is very important to improve the prognosis. In this sense, the clinic experience is frequently the most useful diagnosis instrument to suspect this pathology when we have a confrontation with chronic otorrea and otalgia, common presentation form of this disease. In this report we show a new case of adenoid cystic carcinoma of external auditory canal and review the most significant medical literature existing in relationship with this pathology.

Carcinoma adenoide quístico de CAE / The adenoid cystic carcinoma

El carcinoma adenoide quístico con origen en el conducto auditivo externo es un tumor infrecuente, como ocurre en general con otras neoplasias malignas que asientan en el CAE y oído medio. El diagnóstico precoz de estos tumores malignos del oído es fundamental para mejorar su pronóstico. En este sentido, la experiencia clínica es muchas veces el instrumento diagnóstico más útil para sospechar esta patología cuando nos enfrentamos ante una otorrea y una otalgia crónicas, modo de presentación frecuente de esta enfermedad. En este artículo recogemos un nuevo caso de carcinoma adenoide quístico del conducto auditivo externo y revisamos la literatura médica más relevante que existe en relación con esta patología

[Sarcoma of the larynx. Report of two cases]. / Sarcomas de laringe. A propósito de 2 nuevos casos.

In relation with other laryngeal neoplasms, sarcomas are uncommon tumours. With the object to put in knowledge one chondrosarcoma and one liposarcoma located in the larynx seen in our hospital in a small period of time, we decided to do this publication, discussing the differential clinical aspects of these laryngeal cancers.

Sarcomas de laringe / Two cases of sarcomas of the larynx

Two appearances are outstanding in this case report. First is the clinical picture of chronic laryngeal stridor of a child due to an acquired haemangioma. And that the anatomopathologic subtype of angioma is a pyogenic granuloma noteworthy, as we shall see, the use of the term "pyogenic granuloma" based only on anatomopathological findings in order to circumscribe this lesion.

Two cases of anomalous nervous regeneration seen lastly in our Department suggest us this brief reconsideration specially on the physiopathology of these group of malaties triggered during the development of salivary reflex.

[A giant bilateral concha bullosa causing nasal obstruction]. / Concha bullosa bilateral gigante causante de obstrucción nasal.

Pneumatization of the middle turbinate or concha bullosa is the most common anatomical variant of this structure. Although usually small and asymptomatic, a large concha bullosa may obstruct sinus drainage. We present an uncommon case of massive bilateral concha bullosa that produced complete obstruction of the left nasal cavity and partial obstruction of the right nasal cavity.

[Idiopathic brain herniation in the middle ear and mastoid]. / Herniación cerebral idiopática en el oído medio y mastoides.

Idiopathic brain herniation into the middle ear and the mastoid process is a rare clinico-pathological entity, with only 41 cases described in the literature. It should be suspected in presence of spontaneous otoliquorrhea/rhinoliquorrhea, refractory serous otitis media, or meningitis following acute otitis media in an adult. A new case is presented, with a brief review of the pathogenesis, clinico-pathological, and radiological characteristics of these lesions.
