A 28-year-old male was referred to our hospital because of chest pain and dry cough. Chest x-ray film revealed a tumor mass in the anterior mediastinum indicating invasion into the chest wall and upper lobe of right lung. No tumor was found in the testis. Serum level of alpha-fetoprotein (AFP) was 6,400 ng/ml. Percutaneous biopsy of the tumor suggested yolk sac tumor. The patient was treated with a combination chemotherapy schedule including 30 mg of cisplatin (CDDP) i.v. on Days 1, 2, 3, 4, and 5 and 150 mg of etoposide on Days 1, 2, and 3 as one course therapy. Two courses were employed. Partial response was achieved followed by successful resection of the tumor. This case indicated that a combination chemotherapy CDDP and etoposide combined with surgery could play an active role increasing long-term survival rates in mediastinal yolk sac tumors.

Leiomyoma of the esophagus was surgically treated in 15 patients in 1962-1987. Six patients were asymptomatic and nine presented with dysphagia alone or combined with retrosternal pain, vague thoracic discomfort, dyspnea and cough, or palpitations. Barium swallow and esophagoscopy provided the correct diagnosis preoperatively in most cases. Transthoracic enucleation of the tumor was performed via right thoracotomy in nine patients and left thoracotomy in six. The location of tumor was the upper third of the thoracic esophagus in three cases, middle third in six and lower third in six cases. There was no surgical mortality or morbidity. Surgical removal of esophageal leiomyoma thus gave relief of symptoms, with minimal risk and excellent functional outcome.

We reported 35 cases of neurilemmoma of the neck. All cases had a tumor and 12 cases had neurogenic symptoms or signs such as tenderness, radiating pain, coughing at pressure of the tumor and Horner's syndrome. Tumors originated from the vagus nerve in 10, brachial plexus in 5 and cervical sympathetic chain in 3 cases. The nerve of the origin could not be identified in 17 cases. We classified tumors into 4 types based upon macroscopic nature. Type 1 is that the nerve of the origin could not be identified. Type 2 is that normal nerve passes on the surface of the tumor. Type 3 is that nerve fibers slightly dilated on the tumor surface. Type 4 is that tumor originated from major nerve and tumor surface is covered by the nerve fibers. Postoperative functional deficit of the nerve is rare in type 1 and occurred in the most of type 4 although intracapsular excision was performed. Although neurilemmoma of the neck is rare, postoperative functional deficit can often occur in some types. At the diagnosis of the tumors of the neck we must take the neurilemmoma into consideration. We recommend careful intracapsular excision at the surgery of the neurilemmoma originated from major nerves.

Seven dogs with pulmonary lymphomatoid granulomatosis were reviewed. The disease occurred in six large-breed and one small-breed dogs. The dogs were five to 14 years old (mean, 8.4; median, 7), and four of seven dogs were males. Three dogs had been previously treated with adulticide therapy for canine dirofilariasis. Clinical histories included a progressive respiratory disease characterized by varying degrees of cough, dyspnea, exercise intolerance, and weight loss. Thoracic radiographic features included hilar lymphadenopathy, pulmonary masses of varying sizes, and mixed pulmonary patterns of lobar consolidation with ill-defined interstitial and alveolar pulmonary infiltrates. Cardiovascular changes compatible with chronic dirofilariasis were present in three dogs. The clinical course was usually progressive and fatal. The survival time ranged from six days to four years (mean, 12.5 mos; median, 3 mos). Gross and histologic features included mass lesions with areas of necrosis that replaced normal pulmonary architecture. Cytologically, these lesions were characterized by infiltration with pleomorphic, angioinvasive mononuclear cells that often resulted in vascular obliteration. The infiltrating cells resembled large lymphoid cells that possessed large hyperchromatic nuclei and small amounts of cytoplasm. Systemic lymphoid neoplasia with peripheral lymphadenopathy was diagnosed in two dogs. In both cases, lymph-node cytology was similar to the cellular infiltrates found in the lungs and consistent with a diagnosis of lymphomatoid granulomatosis. These features are compared with previously reported cases of canine lymphomatoid granulomatosis and those features identified in a similar disease described in man.

There has been increased recognition of adenosquamous lung carcinoma since the 1982 modification of World Health Organization (WHO) histologic criteria. However, data on clinical features of this histologic subtype were nonexistent. Medical records of 127 patients with adenosquamous lung carcinoma were reviewed to determine the clinical features, namely, age, race, sex, smoking history, asbestos exposure, symptoms present at the time of diagnosis, stage, treatments, and survival. The age distribution was: less than 40 yr, 3%; 40 to 49, 17%; 50 to 59, 28%; 60 to 69, 32%; 70 to 79, 18%; greater than or equal to 80, 2%. Men constituted 72%, and 90% were smokers. Four smokers had documented asbestos exposure. The symptoms in order of decreasing frequency were cough, weight loss, expectoration, anorexia, chest pain, dyspnea, weakness, hemoptysis, pneumonia, fever, nausea, vomiting, dizziness, and chills. Stage could be ascertained in 120 (95%) patients. Local stage constituted 10%, regional constituted 30%, and distant constituted 60%. Local stage had the best survival, with a projected 5-yr survival of 62%. Median survivals in regional and distant stages were 8 and 4 months, respectively. Symptoms of adenosquamous lung carcinoma were similar to other histologies. Most patients present in regional or distant stages. Local-stage patients had a good long-term survival after surgical excision of the tumor.

The laryngocele is a dilatation of the laryngeal ventricle and represents a rare condition. In most cases there is a typical history. Patients with an internal laryngocele usually complain of hoarseness, dyspnea and cough. Laryngoscopy shows a swelling of the false cord on one side. The external laryngocele presents as a swelling in the neck. In some cases the clinical presentation is not that typical, so that computed tomography (CT) can be a helpful, additional investigation. CT scans show either an air- or mucus-containing tumor at the level of the false cord. This internal laryngocele may proceed into an external one, which presents as a swelling at the level of the hyoid bone. We now present 13 cases of laryngoceles with special regard to the CT and intraoperative findings. In the differential diagnosis other tumors of the larynx are considered, since the mucus-filled laryngocele is difficult to distinguish.

A 50-years-old man was admitted with cough and abnormal shadow on the chest film. The tumor originated from the left vagal nerve in the antero-superior mediastinum. Subcapsular extirpation was performed to save the nerve function, since the tumor located in the site proximal to the branching point of the recurrence nerve. Pathological diagnosis was a benign schwannoma. Though H-E and Bodian stain did not show any nerve fibers in the schwannoma, postoperative hoarseness arose. In this country, 4 cases of subcapsular extirpation have been performed, but all of them had postoperative hoarseness. We think that postoperative hoarseness cannot be prevented by the subcapsular extirpation.

This study aimed to evaluate the usefulness and efficacy of intracordal silicone injection in the treatment of cordal paralysis after thoracic surgery or due to tumor invasion of the recurrent nerve. A total of twenty two patients with cordal paralysis was treated with this procedure. The cause of the cordal paralysis was injury to the recurrent nerve incurred during operation for oesophageal or lung cancer in nineteen patients, and direct invasion of malignant neoplasm to the recurrent nerve in the other three patients. Among the nineteen postoperative patients, fifteen underwent silicone injection 15 to 75 days after thoracic operations during hospitalization. The other four patients were treated after discharge from the hospital. The complaints of the fifteen patients who were treated during hospitalization were dysphonia, aspiration and inability to remove sputum. After treatment, dysphonia had improved in all of these fifteen patients, and aspiration had disappeared in thirteen patients. In four patients who were treated with this procedure 7 months following thoracic operation and three who had cordal paralysis due to invasion of malignant tumors, in all of whom aspiration had not been noted, dysphonia disappeared completely after the silicone injection. To evaluate the effect of silicone injection on the patients' cough force, the intratracheal pressure during cough was measured in patients before and immediately after the treatment. The maximum intrathecal pressure was 25 (+/- 16.57) mmHg before silicone injection. After the procedure, the maximum pressure rose to 95 (+/- 18.13) mmHg. Following the procedure, the patients who had suffered severe debilitating aspiration could remove sputum easily.

The first known case of primary anterior mediastinal endodermal sinus (yolk sac) tumor in a female patient, occurring in a 20-month-old infant, is reported. The child presented with cough, fever, and listlessness. Chest x-ray revealed a right anterior mediastinal mass. At thoracotomy a large anterior mediastinal tumor extending from the neck to the diaphragm was found, and was almost totally resected. Microscopically, the tumor displayed many of the histologic patterns observed in EST. Other neoplastic germ cell elements were not identified. The ultrastructural and immunohistochemical findings further confirmed the diagnosis. Serum alpha-fetoprotein (AFP) level, determined during surgery, was elevated to 65,200 ng/ml, whereas serum beta-human chorionic gonadotropin level was normal. Postoperatively, combination chemotherapy consisting of vinblastine, bleomycin, cisplatin, dactinomycin, cyclophosphamide, and doxorubicin was administered with a maintenance program. After 18 weeks on this regimen all the findings were normal, including serum AFP level. The child is well and disease-free 25 months after diagnosis.

Palliative therapy for previously irradiated patients with symptomatic recurrent endobronchial malignancy is a difficult problem. We have had the opportunity to treat 20 such patients with high dose rate (50-100 rad/min) endobronchial brachytherapy. Eligible patients had received previous high dose thoracic irradiation (TDF greater than or equal to 90), a performance status of greater than or equal to 50, and symptoms caused by a bronchoscopically defined and implantable lesion. The radiation is produced by a small cobalt-60 source (0.7 Ci) remotely afterloaded by cable control. The source is fed into a 4 mm diameter catheter which is placed with bronchoscopic guidance; it may oscillate if necessary to cover the lesion. A dose of 1,000 rad at 1 cm from the source is delivered. We have performed 22 procedures in 20 patients, four following YAG laser debulking. Most had cough, some with hemoptysis. Eight had dyspnea secondary to obstruction and three had obstructive pneumonitis. In 12, symptoms recurred with a mean time to recurrence of 4.3 months (range 1-9 months). Eighteen patients were followed-up and reexamined via bronchoscope 1-2.5 months following the procedure; two were lost to follow-up. All had at least 50 percent clearance of tumor, and six had complete clearance; most regressions were documented on film or videotape. In six, the palliation was durable. The procedure has been well tolerated with no toxicity. We conclude that palliative endobronchial high dose rate brachytherapy is a useful palliative modality in patients with recurrent endobronchial symptomatic carcinoma.
