[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

[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.

[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.

[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.

[Tuberculosis of the parotid gland]. / Tuberculosis parotídea.

We present a case of parotid tuberculosis diagnosed through F.N.A.C. (fine needle aspiration cytology). Due to this rare extrapulmonary location of the tuberculosis, the AA. make a review of the last 12 years concerning literature together with a monographic study of the process.

[Malignant tumor upon pleomorphic adenoma of long development, a case report]. / Tumor maligno sobre adenoma pleomorfo de larga evolución a propósito de un caso.

We have studied a 67 years old woman suffering from a 40 years evolution Pleomorphic adenoma. The specimen weighed 250 g, and showed several areas displaying carcinoma. This report confirms the relationship between long-term evolution and malignant transformation.

[Epidemiology of cancer of the larynx in the region of Cartagena from 1972 to 1984]. / Epidemiología del cáncer de laringe en la comarca de Cartagena en el período 1972-1984.

We have carried out a survey on larynx cancer for the Cartagena region between the years 1972 and 1984 out of a population that varies from 210,944 to 250,233 inhabitants and a total number of 207 cases with histopathology control. The average incident valuation per every 100,000 inhabitants is 6.9 for the total population and 13.74 for males. An important fact is the amount of supraglottical carcinomas which have been discovered, meaning 51.08%; more common in males under 60, which has a very close connection with the consumption of black tobacco. The glottical carcinoma represents 46.80% of the cases, more common in males over 60 not related to a smoking habit. The high risk population is formed by males between 55 and 65 who are heavy smokers and drinkers and do manual labour.

[Clinicopathologic characteristics of laryngeal neoplasms in the region of Cartagena from 1972 to 1984]. / Características clinicopatológicas de las neoplasias laríngeas en la comarca de Cartagena durante el período 1972-1984.

We have carried out a research into the clinicopathological characteristics of the cancer of larynx between 1972 and 1984 in the area of Cartagena, with a populations that oscillated between 210,944 and 250,233 inhabitants, and over a number of 207 cases. We observe that the symptom to which the patients attach most importance and the reason why they most often consult is dysphonia or voice-alteration, and that its clinical development average time until diagnosis is of 6.08 months. It is to be pointed out the proportion of supraglottic carcinomas which at the moment of diagnosis usually show a T3 or a T4 stage and palpable adenopathies in a third of the patients. On the contrary, glottic carcinomas are usually T1 lesions and without satellite adenopathies. With regard to the histologic type, the great majority of cases belong to epidermoid carcinomas, followed at a great distance by warty carcinomas and finally by pseudosarcomas.
