Extra-canalicular osteomas of the temporal bones are rare benign tumours. We report a retroauricular osteoma in a 18 years old patient. Usually symptomless, they may present for cosmetic reasons. We briefly comment this type of tumours.
Chordoma is an uncommon neoplasia with very aggressive behavior and very high local recurrence rate. It remains a difficult problem for the surgeon. A case of cervical chordoma in a 30 years old woman is reported. The patient had a retropharyngeal mass and changes in the quality of speech. A transoral approach was used to obtain complete removal. The biological, clinical and diagnostic characteristic of cervical chordomas are reviewed.
The inflammatory pseudotumor of the head and of the neck is a lesion of unknown etiology which affects the orbita more frequently but cases have also been described in the paranasal sinuses, larynx, mouth, cervical column and by direct extension from the orbita in the Central Nervous System. In the majority of cases, it behaves as a limited benignant inflammation within the osseous walls of the area where it is to be found; other times it destroys the osseous limits and invades the surrounding areas, behaving as a neoplasia. It must be distinguished from sinusitis, granulomatous inflammations, vasculitis, diseases of the collagen, sarcoidosis, neoplasias and benignant tumours. We present a case of inflammatory pseudotumour, occupying the right maxillary sinus, nasal fossa and rhinopharynx. Surgical extirpation has been the treatment used.
ORL emergencies attended at in a general hospital for a year were studied from 1-7-1990 to 30-6-1991. 168,145 emergencies were received of which 3,101 (1.8%) were attended by an otorhinolaringologist. The age, sex, arrival time, aetiology, treatment, admissions and the admissions where AEP (Appropriateness Evaluation Protocol) criteria was applied were thoroughly examined. The most numerous pathologies presented were infectious inflammations (41%), hemorrhages (21%), and foreign bodies (18.5%). But the most frequent aetiologies were epistaxis (16.3%), otitis media (14.8%) and otitis externa (14.8%). Most patients arrived generally between 9-12 hrs. (21.3%), and 17-20 hrs. (25.4%). The average age was 38.8 years old, though there was a significant difference depending on the pathology presented. Infectious inflammations emergencies were usually the youngest age group (average age 32) and tumoral processes the eldest (average age 60), 5% of the cases were admitted. These admissions accounted for only 17.9% of total admissions. Because AEP criteria was employed 97.5% of admissions presented inclusion criteria.
Cystic lymphangiomas are abnormalities derived from lymphatic vessels that are characterized by the formation of cysts. The are located generally in head and neck and occur most frequently in children. They rarely appear in adults. We present a case of lymphangioma and review the disorder.
Otogenic intracranial complications are now rare. Meningitis is the most frequent, followed by cerebral abscess. In spite of diagnostic and therapeutic advances, cerebral abscess has a high mortality. We report four cases seen in our service over the last five years and their treatment. The subject is reviewed.
We report a case of laryngeal mucoepidermoid carcinoma that was diagnosed in the Hospital Miguel Servet of Zaragoza. The unusual tumor site and difficult diagnosis were notable and, above all the fatal outcome after local recurrence and metastasis in spite of good overall prognosis.
