[Nasoalveolar cyst. Five new cases]. / Quistes nasoalveolares. Presentación de 5 nuevos casos.

Nasoalverolar cyst are nonodontogenic maxillary cysts, rare and benign, which are more common in females and blacks. Their diagnosis can be established mainly on the clinical presentation, being usually asymptomatic during several years until they are large enough to cause cosmetic deformities and/or nasal obstruction, with asymmetrical alar flare. The treatment of choice is the complete surgical excision via a sublabial approach. Five cases diagnosed and treated at the Santa Maria del Rosell Hospital are reported, describing the most relevant clinican and pathological findings, so the diagnostic ant therapeutic methods.

Quistes nasoalveolares. Presentación de 5 nuevos casos / Nasoalveolar cyst. Five new cases

Inverted papilloma is a benign sinonasal tumour with a high recurrence rate and its treatment must be surgery, using endonasal surgery or external aproach. We present a retrospective study of 23 cases treated in our center from 1988 to 2003. There 15 males and 8 females with a mean follow-up of 6 years. The recurrence rate was 40,9%. Patients who underwent endonasal surgery had a recurrence rate of 36,6% and those who underwent external approach surgery had a recurrence rate of 45,5%. There was a 4,5% of association with carcinoma. Endonasal surgery might be a valid surgery approach for the treatement of inverted papilloma in select cases

Nasoalveolar cyst are nonodontogenic maxillary cysts, rare and benign, which are more common in females and blacks. Their diagnosis can be established mainly on the clinical presentation, being usually asymptomatic during several years until they are large enough to cause cosmetic deformities and/or nasal obstruction, with asummetrical alarflare. The treatment of choice is the complete surgical excision via a sublabial approach.

[Laryngeal fibroendoscopic surgery. Our experience]. / Cirugía fibroendoscópica laríngea. Nuestra experiencia.

Since 1992, when our department acquired a flexible fiberscope with a working channel, we have used it in surgery on the upper respiratory and digestive tract. We call our technique laryngeal fiberscopic surgery. We report the results of four years of experience in this field. A total of 368 surgical interventions were performed, almost half to remove benign lesions of the vocal cords (polyps, nodules, etc). This technique is a major advance in our field of study. Its main advantages are avoidance of general anesthesia and hospitalization, reduction of surgical risk, and savings of time and money. We consider it to be a useful alternative to traditional direct laryngoscopy (Kleinsasser technique) for many applications.

Cirugía fibroendoscópica laríngea. Nuestra experiencia / Laryngeal fibroendoscopic surgery. Our experience

Desde que, en 1992, nuestro servicio adquirió unfibrolaringoscopio flexible con canal de trabajo, comenzamos a realizar con él intervenciones quirúrgicas en la vía aerodigestiva superior, desarrollando una técnica a la que hemos denominado cirugía fibroendoscópica laríngea. En el presente artículo exponemos nuestra experiencia en los últimos cuatro años en este campo. Hemos realizado un total de 368 intervenciones, de las cuales casi un 50 por ciento han sido extirpaciones de lesiones benignas de cuerda vocal (pólipos, nódulos, etc.). Creemos que supone un gran avance en el campo de nuestra especialidad, siendo sus principales aportaciones, evitar la anes-tesia general y el ingreso hospitalario, la reducción de riesgos quirúrgicos y el ahorro de gastos económicos y de tiempo. Consideramos que es una alternativa más que razonable a la clásica laringoscopia directa en suspensión (técnica de Kleinsasser) en muchas de sus indicaciones (AU)

[Sarcomatous carcinoma versus malignant fibrohistiocytoma. Differential diagnosis of a case of cervical presentation]. / Carcinoma sarcomatoide versus fibrohistiocitoma maligno. Diagnóstico diferencial en un caso de presentación cervical.

A case is presented of cervical sarcomatoid carcinoma that was initially confused with malignant fibrohistiocytoma. The similarity in their histological features and compatible immunohistochemical tests make it necessary to include sarcomatoid carcinoma in the differential diagnosis malignant fibrohistiocytoma. Many atypical presentations of malignant fibrohistiocytoma may be true sarcomatoid carcinomas. Our case is special because the patient had a recent spinocellular carcinoma of the lip, in which the undifferentiated portion had originated lymph node metastasis.

[Nasopharyngeal melanoma: a case report]. / Melanoma de nasofaringe. A propósito de un caso.

The AA. present a case of disseminated primitive melanoma of the rhinopharynx. The main difficulty was to establish the differential diagnosis, owing to the rarity of this tumor's type in such a sitting. The patient showed intracranial metastases which took him to death in a short term.

[Cystic adenoid carcinoma. Review of last five years in our ENT department (1987-1991)]. / Carcinoma adenoide quístico. Revisión de los últimos cinco años en nuestro Servicio de O.R.L. (1987-1991).

We present 4 cases of adenoid cystic carcinoma from different locations (parotid, submaxillary, larynx and auditory duct) and we underline the supraglottic origin of one of them. We point out the good clinical behaviour of this carcinoma, with a long tested survival, more than 5 years, in 2 of our cases. All of them showed morphological features independently of the sitting.

[Bilateral facial palsy, Bell's type]. / Parálisis facial bilateral de Bell.

Report of one case of Bell's peripheral bilateral facial paralyse in a woman, 62-year-old. This bening acute cranial polyneuritis is a frequent complaint, but its bilaterally makes the interest of the case. The clinical course of the illness parallels that of the unilateral cases, both having a good pronostic.

[Nasal angiofibroma in an adult]. / Angiofibroma nasal. A propósito de un caso de presentación en la edad adulta.

We have studied a nasal Angiofibroma in a 71-years-old male, who had not undergone any male-hormonal-therapy. The age of occurrence and the clinical course of this case made the tumor very unlikely to be a silent puberal nasal angiofibroma. After morphologic exam and exclusion of other bleeding entities of the nasal cavity we arrived at the diagnosis of nasal angiofibroma. We believe that this tumor might be arisen "ex novo" and that the nasal angiofibroma of elderly people might be a new entity.

[Pyolaryngocele as a focal disease]. / Piolaringocele como enfermedad de foco.

Report of one case of Laryngocele in a 49 years old male, without previous anamnestic data, but urticaria and orchitis recurrens till the removal of the pyolaryngocele. The diagnosis was awkward because of its rare behaviour with torpid evolution and distant manifestations. The AA. think it was consistent with a septic focus.
