The words pseudocyst of the pinna was suggested in 1966 by Engel for those intracartilaginous swellings of the auricula, presenting in young healthy males without traumatic precedents or previous manipulation. The AA. report 4 cases diagnosed and treated in their Hospital Department. A woman, 85, was one of them. Review of the subject's literature.
We present 2 cases of retropharyngeal abscess in adults as complication of acute tonsillitis and cervical pyogenic osteomyelitis, respectively. These cases confirm that retropharyngeal abscess has a significant morbi-mortality despite of new antibiotic drugs introduced. A review of the present characteristics of the complaint is treated in this paper.
Reporting one case of pseudocyst of the auricle in a young male, 18, white and wealthy, diagnosed and treated. Bibliographical review of this condition and explanation of its etiopathogenetic, clinic and therapeutical characteristics, as well. This deformity seems to be more prevalent as the number of published cases may suggest.
Peripheral facial paralysis from tumoral origin is scarce in number, in spite of possible manifold causative growths. One case in which the palsy was associated to a rhinopharyngeal neoplasm is reported and possible ways of nerve involvement discussed. Although progression seems to be the most probable hypothesis in this instance, only the anatomo-pathological exam has affirmative value.
The Electroneurography (ENoG) is one of the most employed electrodiagnostical techniques in the appraisal of acute facial palsies (AFP). Since 1989 we have to resort systematically to this exploration in our ENT-Department, which task previously was province of the Neurophysiological Service. On accordance with the exam's results we then express the prognostic, regarding the seriousness of the paralysis, and so settle the indication or the abstention for the rehabilitative treatment. We report here a review of 92 APF's seen during 1990 and consider their evolutive course which is compared with that in advance supposed to be. In the light of our final results we venture to say that ENoG, in our hands, is a good prognostical indicator and also is an adequate standard of judgement in order to recommend the rehabilitative management of AFP.
A 43-year-old female patient complaining with odynophagy since a month and a half without response to the medical treatment is presented. The pharynx exam showed an asymmetric swelling in the right tonsillar surface and the radiology provided evidence of calcareous concretions as responsible cause of the picture.
A 34 year-old man, with a two centimeter diameter quickly growing nodule on the auricular pavillion is presented. After mass excision the histologic diagnosis of pilomatrixoma was made. Pilomatrixoma is a rare benign tumor arising on the hair matrix. The differential diagnosis include pilomatrix carcinoma, a locally and recurrent aggressive tumor capable to make pulmonary metastasis. A review of the literature is included, with emphasis on the clinical and histopathological aspects and the therapeutic attitude.
If Hodgkin's disease involving the oropharynx is uncommon, Hodgkin's disease confined to the oropharynx is exceptional. The AA. report a case sitting in the oropharynx. Biopsy of nasopharynx in order of staging the disease is suggested.

Facial nerve neurinomas are unusual tumors which originate fin the Schwann cells of the nerve sheath. Diagnosis of these tumors has improved in the last years due to radiological and clinical advances. Here presented is a case study of a patient with neurinoma of the primary facial nerve which clinically manifested itself as a recurrent facial paralysis. A high resolution T-C scan was sufficient for tumour identification, treatment consisted in a middle fossa approach and tumour removal followed by hypoglossa-facial anastomosis.
A 43 year-old man with a cystic mass on the side of the neck was admitted to the hospital for possible branchial cyst. The histopathological analysis showed a carcinoma developed on a branchial cyst. After reviewing the literature, we conclude that carcinoma developing on a branchial cyst is uncommon, if, indeed, it exists at all. The diagnostic criteria should be adhered to strictly. When confronted with this histopathologic diagnosis, the possibility of cystic metastasis to the neck of a squamous carcinoma of unknown origin should be considered.
Differentiating between Wegener's granulomatosis and other destructive centrofacial lesions often is difficult for clinicians and pathologists. It has become more confusing since what until now was known as "malignant centrofacial granulomatosis" seems to be a peripheral T-cell lymphoma. The case of an 83-year-old male recently diagnosed as angiocentric peripheral T-cell lymphoma which presented as a destructive centrofacial process is reported. The probable pathogenic role of Epstein-Barr virus (EBV) is highlighted.
Forestier's disease is characterized by the formation of vertebral bridges which joint the ventral aspect of the vertebral bodies by ossification of the anterior vertebral longitudinal ligament. A 58-year-old man with idiopathic ankylotic hyperostosis had pronounced osteophytosis of the neck that produced the unusual symptom of dysphagia. The literature is reviewed and the pathogenic criteria, diagnosis, and therapy are discussed.
Lateral radiography of the neck is performed for the study of radio-opaque esophageal foreign bodies that are not visualized by indirect laryngoscopy. This projection may reveal a calcified linear image behind the cricoid cartilage due to calcification of the posterior lamina. In such cases, esophagoscopy and/or computed tomography must be performed to determine whether the image is due to an anatomic variant or a true foreign body.
