Perineuromas (PN) are uncommon, slowly growing, usually benign tumors composed of well-differentiated perineural cells. Two variants are recognized: intraneural perineuromas and soft tissue perineuroma, which includes a sclerosing subset of tumors. They are usually reported in the adult population. We present three cases of soft tissue perineuromas in children. One was located in the deep soft tissue of the retroperitoneum in a 14-year-old girl, the second one in the left thumb of a 14-year-old boy, and the third one in the index finger of a 16-year-old boy. This report, which describes the clinicopathologic, immunohistochemical, and ultrastructural features of these tumors, should alert pathologists to the occurrence of perineuromas in children. A review of the English language literature on perineuromas in children is also included.

A choristoma is a tumor-like mass of normal tissue in an “abnormal” location. Lingual osseous choristoma, previously known as osteoma of the tongue, is a rare entity: we found documentation of eight cases at our center during the 10-year period between 1987 and 1996. These cases were analyzed along with 50 others reported in the English language literature between 1913 and 1996. Lingual osseous choristoma frequently occurs during the third and fourth decades of life, and predominantly affects women (81 %). Most of the osseous choristomas in our review were located in the posterior third of the tongue, primarily at or close to the foramen cecum or circumvallate papillae (87.9%). While 39.7% of the patients were asymptomatic, the remaining patients complicated of symptoms including a lump in the throat (25.8%), dysphagia (6.9%), gagging (5.1%), nausea (3.4%) and irritation (3.4%). Treatment of lingual osseous choristoma consists of simple excision. The tumor's origin has been discussed elsewhere.

Pectoralis major rupture is uncommon. Injury usually occurs from sporting activities. The incidence and management of pectoralis major rupture is not well known, despite 74 case reports in the English language literature over the past 34 years. Two cases of chronic pectoralis ruptures and their successful surgical management are described. A review of the literature shows that most injuries occur at the humeral insertion, and most are complete ruptures. Distinguishing between complete and partial ruptures is important. Complete ruptures are best treated surgically in the acute situation. When chronic complete ruptures present, surgical repair yields fair to good results. Acute partial ruptures can be effectively managed conservatively or with surgery. Chronic partial ruptures can be managed surgically with good results, following unsatisfactory conservative management in the acute situation.

Objective To describe a case of isoniazid-associated psychosis and review the incidence of this adverse effect. Data Sources Information about the patient was obtained from the medical chart. A MEDLINE search of the English-language literature published from 1950 to 1992 was conducted and Index Medicus was manually searched for current information. Study Selection All case reports describing isoniazid-associated psychosis were reviewed. Data Extraction Studies were evaluated for the use of isoniazid, symptoms of psychosis, onset of symptoms, and dosage of isoniazid. Data Synthesis The case report is compared with others reported in the literature. The incidence of isoniazid-associated psychosis is rare. Conclusions The mechanism of isoniazid-associated psychosis is uncertain. It appears that isoniazid was associated with the psychosis evident in our patient and in the cases reviewed.

We describe the case of a 65-year-old woman who presented with left nasal obstruction. Clinical and radiographic examinations revealed the presence of a soft-tissue mass that had obliterated the left nasal cavity. The mass was completely excised via an endoscopic approach. Histopathologic examination identified the tumor as an ossifying fibrosarcoma. The patient recovered uneventfully and remained free of disease at the 2-year postoperative follow-up. To the best of our knowledge, no case of an ossifying fibrosarcoma of the nasal cavity has been previously reported in the English-language literature. We discuss the features of this case and the clinical presentation, diagnosis, and management of fibrosarcomas of the nasal cavity and paranasal sinuses.

Lipomas are the most common type of soft tissue mesenchymal tumors. They are typically located subcutaneously and consist of mature fatty tissue. When they occur under the enclosing fascia, they are called deep-seated lipomas. Infrequently, lipomas can arise inside the muscle and are called intramuscular lipomas. Intramuscular lipomas have been commonly investigated and categorized in the same group as other deep-seated and superficial lipomatous lesions. Their clinical, histological and imaging characteristics may resemble well-differentiated liposarcomas, further adding to the difficulties in the differential diagnosis. This article summarizes the available literature and describes the typical epidemiological, pathological and clinical features of intramuscular lipomas, as well as delineating their treatment and prognosis.

Object The authors' goal was to better define the relationship between biomechanical parameters of a helmeted collision and the likelihood of concussion. Methods The English-language literature was reviewed in search of scholarly articles describing the rotational and translational accelerations observed during all monitored impact conditions that resulted in concussion at all levels of American football. Results High school players who suffer concussion experience an average of 93.9g of translational acceleration (TA) and 6505.2 rad/s2 of rotational acceleration (RA). College athletes experience an average of 118.4g of TA and 5311.6 rad/s2 of RA. While approximately 3% of collisions are associated with TAs greater than the mean TA associated with concussion, only about 0.02% of collisions actually result in a concussion. Associated variables that determine whether a player who experiences a severe collision also experiences a concussion remain hypothetical at present. Conclusions The ability to reliably predict the incidence of concussion based purely on biomechanical data remains elusive. This study provides novel, important information that helps to quantify the relative insignificance of biomechanical parameters in prediction of concussion risk. Further research will be necessary to better define other factors that predispose to concussion.

The Subject

✓ Although sudden deterioration and death is a widely recognized complication in patients with benign tumors of the third ventricle area, the exact incidence of this dreaded occurrence is unknown and the reports in the literature on the subject are largely anecdotal. Neither risk factors nor the etiology of the sudden death have been analyzed. The vast majority of these benign tumors are colloid cysts, and the presence and degree of ventricular dilatation and herniation associated with these tumors as cited in the reports are quite variable. The authors report a case of sudden death in a 27-year-old woman with a subependymoma of the left lateral and third ventricles. A review of the literature is included in an attempt to discern identifiable risk factors for sudden death in patients with tumors of the third ventricle area. Since this potential complication is known to exist in patients with otherwise benign tumors amenable to surgical resection, the authors recommend either prompt removal of the tumor on discovery or close monitoring of the patient if surgery is to be delayed.

Facial paraganglioma is an extremely rare tumor that originates from abnormal paraganglionic tissue situated in the intrapetrous facial canal. A review of the English-language literature shows that only 8 cases of facial nerve paraganglioma have been published. In each case the facial glomus presented itself sporadically, completely independent of any other form of paraganglioma. This study reports an intrapetrous facial glomus that occurred in a case of multiple paragangliomas with a hereditary pattern. To our knowledge, this is the first report of such a combination.

In this article we report the case of a 41-year-old man with bilateral aural fullness and hearing loss. On examination he was found to have bilateral, dehiscent anterior canal walls with herniation of the mandibular condyle. This herniation partially obstructed the canals and contributed to his symptoms. To the best of our knowledge, this is only the third reported case of bilateral spontaneous temporomandibular joint herniation, and only 28 cases of unilateral spontaneous herniation can be found in the English language literature. While it is a rare phenomenon, it should be considered when evaluating a patient with fluctuating ear symptoms.

Abstract OBJECTIVE Radiosurgery-associated second tumors have been reported in four isolated patients during the past 2 years. In our own experience, we are aware of two additional patients. The purpose of this report is to call attention to this potentially emerging problem. METHODS A review of the English-language literature concerning patients with radiosurgery-associated second tumors was performed. In addition, we report on two patients in our own practice who were treated in the past year. RESULTS Four patients were found in the literature, and two additional patients were seen by the authors. Malignant tumors occurred as early as 6 years after radiosurgery. The pathological findings in three of these four malignant tumors were glioblastoma multiforme. Benign tumors developed between 16 and 19 years later. Tumors developed both within the full-dose prescription volume and in the lower-dose periphery. Of interest, three of the six patients experienced complications of the radiosurgery treatment before developing second tumors. CONCLUSION Although patients will increasingly be reported with second tumors after radiosurgery in the future, the overall incidence seems quite low and should not alter current radiosurgical practice. However, continual surveillance of treated patients should be considered.
