The 14 subglottic and glottic-subglottic carcinomas treated in the Otolaryngologic Department of the AA. between 1984 and 1989 are reviewed. Check of literature about subglottic carcinomas.
Angiolymphoid hyperplasia with eosinophilia is a multisystemic disease characterized mainly by cutaneous nodules, vascular proliferation with atypical histiocytoid endothelial cells and numerous eosinophiles, often with blood eosinophilia. It use to recur "in situ" and persist after surgical excision. The AA. review the literature about this rare tumor and present the clinical and histopathological features of a case of Angiolymphoid hyperplasia with eosinophilia of the tongue.

Pseudocyst of the auricle is a spontaneous intracartilaginous collection of serous fluid in the anterior aspect of the auricle. These cysts occur frequently in young healthy Chinese males. Engel (1966) was the first to report a series of pseudocysts of the auricle in Chinese. Its etiology is unknown, treatment is difficult and recurrence frequent. In the paper a case report is presented and a review of the literature of this rare condition is done.
A case report of an extramedullary plasmocytoma located in the nasal cavity is presented. Although infrequent in the ENT practice, they use to occur in the head and the neck. The AA. remark the importance of performing immunohistochemical tests to assess an accurate differential diagnosis with some other neoplasms and, specially, with plasma cell reactive granuloma.
The onset of the bone radionecrosis is a relatively unusual problem which should be considered in the differential diagnosis of recurrences of irradiated tumors showing a high degree of aggressiveness. The AA. present a case report of a re-operated lower lip carcinoma which underwent further radiation therapy. A bony mandibular lesion was then observed, which led to the diagnosis of tumoral invasion at the mandible, and a partial mandibulectomy was then performed. The histopathological examination revealed a bone necrosis, probably due to radiotherapy. The clinical features and therapeutic management of mandibular osteoradionecrosis are commented.
The AA. present 2 cases of olfactory Neuroblastoma in different stages of histologic differentiation, which are compared. Bibliographic survey of the entity.
Non-traumatic otologic diseases are a rare cause of pneumocephalus. Among them, few reports have been described whereas it occurred following oto-surgery. We present a case report of pneumocephalus in a patient who presented with CSF-otorrhea, headache, disorientation, after recent mastoid radical surgery. The definite diagnosis was done by CT scan imaging. We realize a review of the literature about this subject, we describe the clinical and diagnostic features, its possible physiopathology, and its surgical management.
Granular cell tumor is an unusual tumor of probably neuroectodermal histogenesis, originally reported by Abrikossoff (1926) as a myoblastoma. Of the about 1,200 reported cases since then, 50% are found in the head and neck. Of these, 10% have a laryngeal localization. An infrequent case report of glottic localization which was solved by chirurgical excision with free margins, is presented. The features of the laryngeal presentation, is reviewed and iconography with immunohistochemical techniques of their pathologic characteristics, is showed.
A case report of ear undifferentiated squamous cell carcinoma is presented. The patient complained pain and suppurative ear, which lead to us to practise an exploratory atticotomy, and therefore the tumor was detected on its early stages. It is a very interesting case report due to its unusual localization, and to the early diagnosis to improve the prognosis of these patients.
