Computed tomographic examinations were performed on 24 patients with entirely submucosal laryngeal mass lesions. Presenting complaints were hoarseness (17 patients), dysphagia (1 patient), airway obstruction (5 patients), and a cervical nodal metastasis (1 patient). The masses were visible endoscopically as submucosal bulges in 21 patients. Three other patients presenting with hoarseness and vocal cord paresis or paralysis had otherwise negative endoscopy and a mass demonstrated on CT. Thirteen patients were eventually diagnosed as having squamous cell carcinoma, which was the primary working diagnosis following CT in 12 cases. The group of 13 carcinoma patients had a range of two to five endoscopic procedures with one to four negative biopsies and a 6 week to 9 month delay in histologic confirmation of cancer. Other lesions included five laryngoceles, two chondrosarcomas, and one case each of paraganglioma, fibrosarcoma, lymphoma, and tuberculous laryngitis. Computed tomography is an indispensable tool for evaluating submucosal laryngeal masses or otherwise unexplainable symptoms (usually hoarseness) that might herald such a mass. A definite submucosal mass on CT should prompt a deep or wedge biopsy to reach a pathologic diagnosis. This will avoid the delay in diagnosis that frequently occurs in these patients.

A patient developed isolated numbness, 1st confined to the lateral nose and upper lip, but later involving the cheek, lower lip, upper gingiva, and the palate. This numbness was later associated with paresis of the muscles of the upper lip and angle of the mouth and with ipsilateral lower lid droop (the "numb cheek-limp lower lid" syndrome). Squamous cell carcinoma was discovered infiltrating the infraorbital nerve and distal branches of the facial nerve. Cheek numbness associated with lower eyelid or upper lip weakness may herald a neoplasm affecting the infraorbital nerve and distal facial nerve branches.

A 38-year-old male who presented with trigeminal nerve paresis was found to have a cerebellopontine angle tumor. The tumor was subtotally removed. Multiple histological sections showed no malignant changes, and the diagnosis was typical epidermoid cyst. Tumor growth recurred twice and the diagnosis after the third operation was epidermoid carcinoma. A review of the available literature yielded only 22 reported cases of malignant intracranial epidermoid cyst.

Neurologic abnormalities were the predominant historic and physical findings in 5 dogs and 2 cats with primary nasal cavity tumors that had invaded the cranial vault. Seizures, behavior changes, and obtundation were the most common signs. Other neurologic signs included paresis, ataxia, circling, visual deficit, and proprioceptive deficit. Although 1 dog and 2 cats had historic findings of mild respiratory disease, no physical abnormalities related to the respiratory tract were found in any of the 7 animals. Nasal cavity neoplasia was suggested by radiographic and computed tomographic studies and was confirmed histopathologically in each case. The nasal tumor types in the 5 dogs were epidermoid carcinoma (n = 1), adenocarcinoma (n = 2), solid carcinoma (n = 1), and anaplastic chondrosarcoma (n = 1). An esthesioneuroblastoma was found in each cat. Radiation therapy was effective for 3 months in palliating the clinical signs in the 2 dogs in which it was used. Neoplasia of the nasal cavity should be considered in the differential diagnosis for animals with neurologic signs suggestive of cerebral disorders.

Malignant fibrous histiocytomas of the storiform pleomorphic type were found in the lower legs of two patients, 79 and 42 years of age. In the first, dermatofibrosarcoma protuberans, in the second, squamous cell carcinoma, had to be discussed. In the first patient, the tumor arose in the area of a preexisting paresis of the superficial peroneal nerve; the second patient developed the tumor in fistulous osteomyelitis existing since childhood.

A case of epidermoid carcinoma arising in an epidermoid cyst in the cerebellopontine angle is presented. Clinical features and CT appearance are discussed in comparison with those of benign epidermoid cyst. A 43-year-old man was admitted to the Department of Neurosurgery, University of Tokyo Hospital on April 14, 1983, with complaints of right facial numbness and weakness of six months' history. On neurological examination, sensation of the right half of the face was decreased in all modalities. Marked atrophy of the ipsilateral temporal muscle was also noted. Right facial paresis of peripheral type was evident. Gag reflex was decreased on the same side. Except for a slightly increased left deep tendon reflexes, there were no pyramidal tract signs. A CT without contrast material failed to show any abnormalities. A postcontrast CT demonstrated an irregular enhancement in the right cerebellopontine angle. The finding of asymmetry of the ambient cistern indicated minimum mass effect on the metrizamide CT cisternography. Suboccipital exploration of the right cerebellopontine angle was carried out on April 28, 1983. Leaving a part of the capsule indenting the pons between the roots of the fifth and the seventh nerve, we removed a white pearly tumor. Histological diagnosis was typical epidermoid cyst. He left the hospital one month later with signs of the right seventh and the eighth nerve. His postoperative course, however, was beyond our expectation. Over a few months following his discharge, left hemiparesis as well as horizontal and vertical nystagmus gradually developed. He was readmitted on November 10, 1983. A postcontrast CT revealed enlargement of the enhanced lesion filling the right ambient cistern.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of epidermoid carcinoma in the cerebello-pontine (CP) angle is presented. A 42-year-old male was admitted with a complaint of experiencing double vision for four months in January, 1992. During neurological examination, right abducens palsy, right facial dysesthesia, and atrophy of the right temporal muscle were noted. Magnetic resonance (MR) imaging revealed a mass of low intensity in the right CP angle, which was prominently enhanced with gadolinium. Malignancy was suspected because the tumor on MR enlarged rapidly in a month, so the first surgical resection was performed. Suboccipital exploration of the right CP angle was performed in February. At first, a fragile, pearly part of the mass typical of epidermoid was exposed behind the seventh and eighth cranial nerve complex. Then, a grayish, fibrous part was exposed, which involved the fifth cranial nerve and was attached to the tentorium and the brainstem. Histological diagnosis of the fragile part of the tumor revealed a typical epidermoid cyst and that of the fibrous part was squamous cell carcinoma. During postoperative examinations on other parts of the body, such as endoscopic studies of the trachea and the esophagus, no abnormality was shown. Therefore the tumor was diagnosed as a primary intracranial epidermoid carcinoma. Post-operatively, conventional fractionated external-beam focal irradiation was carried out, which caused regression of the residual tumor for eleven months. Subsequently, palsy of the right side of the tongue and paresis of the contralateral side of the extremities and face developed with increase of the right abducens palsy. MR imaging indicated regrowth of the tumor. The second operation via the subtemporal approach was unsuccessful, because the tumor was fibrous and firmly attached to the brainstem.(ABSTRACT TRUNCATED AT 250 WORDS)

Usually dysphonia is the result of a functional disorder of the larynx. It can also result from paresis or paralysis of a hemilarynx. Four patients, men aged 57, 41, 42 and 18 years, had a neurological cause of paralysis of a hemilarynx. Processes responsible for this kind of pathology can appear at three different levels: central, nuclear and peripheral. Each of the four patients had a disorder at the peripheral level: two had a tumour, in one the vagus nerve was severed during lobectomy for squamous cell carcinoma (iatrogenic), and in the last one an upper respiratory viral infection was the probable cause. Other causes of these peripheral lesions are toxicological, traumatic or idiopathic. When dysphonia does not improve within three weeks, inspection of the larynx and palpation of the neck, including examination of the aspect and mobility of the vocal folds by an otorhinolaryngologist should be performed. If paresis of a hemilarynx is seen, an orientation examination of the cranial nerves and selective additional examination is necessary, as paresis of a hemilarynx is a symptom, not a diagnosis.

A 50-year-old female presented with primary intracranial squamous cell carcinoma (SCC) at the right cerebellopontine angle manifesting as right facial nerve paresis. She had undergone gross total removal of a right cerebellopontine angle epidermoid cyst 10 years before and had done well until recently. Magnetic resonance imaging showed a heterogeneous tumor with markedly enhanced irregular margin. Subtotal removal of the tumor was achieved. Histological examination showed moderately differentiated SCC. After surgery, she underwent chemotherapy and gamma radiosurgery. She is now well 5 years after the diagnosis of SCC.

Nasopharyngeal carcinoma (NPC) is a tumor arising from the epithelial cells that cover the surface and line the nasopharynx. The annual incidence of NPC in the UK is 0.3 per million at age 0-14 years, and 1 to 2 per million at age 15-19 years. Incidence is higher in the Chinese and Tunisian populations. Although rare, NPC accounts for about one third of childhood nasopharyngeal neoplasms. Three subtypes of NPC are recognized in the World Health Organization (WHO) classification: 1) squamous cell carcinoma, typically found in the older adult population; 2) non-keratinizing carcinoma; 3) undifferentiated carcinoma. The tumor can extend within or out of the nasopharynx to the other lateral wall and/or posterosuperiorly to the base of the skull or the palate, nasal cavity or oropharynx. It then typically metastases to cervical lymph nodes. Cervical lymphadenopathy is the initial presentation in many patients, and the diagnosis of NPC is often made by lymph node biopsy. Symptoms related to the primary tumor include trismus, pain, otitis media, nasal regurgitation due to paresis of the soft palate, hearing loss and cranial nerve palsies. Larger growths may produce nasal obstruction or bleeding and a "nasal twang". Etiological factors include Epstein-Barr virus (EBV), genetic susceptibility and consumption of food with possible carcinogens--volatile nitrosamines. The recommended treatment schedule consists of three courses of neoadjuvant chemotherapy, irradiation, and adjuvant interferon (IFN)-beta therapy.
