A 65-year-old woman presented with stridor revealed a mass on a chest X-ray on physical examination. A huge goiter arising in the left lobe of the thyroid had extended retroesophageally and across the midline to the right side of the posterior mediastinum far caudally down to the level of the carina. The trachea was remarkably compressed. Surgery was performed via a combined thoracic and cervical approach, and the tumor was completely removed with resultant relief from stridor. The patient is presently doing well at 1 year after the operation.

We report an adult case of asymptomatic congenital tracheal stenosis. A 42-year-old woman was admitted to our hospital, whose chief complaint was tongue pain. Clinical examination revealed a tumor 35 x 20 mm in diameter along the middle, right edge of the tongue, and histopathological examination determined a diagnosis of squamous cell carcinoma of the tongue. She had no history of dyspnea, stridor nor recurrent pneumonia, and enjoyed playing table tennis in her daily life. Physical examination, electrocardiogram, spirogram and laboratory data showed no abnormal signs although chest roentgenogram revealed a narrowed trachea 6 mm in diameter, however, the tracheal stenosis was not noted at the time. On the 10th hospital day, radical operation for cancer of the tongue including right hemiglossectomy and supraomohyoid neck dissection, were performed. Oral intubation was not successful, and a tracheostomy was conducted. The trachea was incised, and revealed that complete tracheal rings existed without posterior membraneous tissue. The operation time was limited because of high airway pressure for a narrow tracheal tube (5 mm in diameter). The main postoperative complication was one crust formation in the tracheal lumen that resulted in CO2 narcosis due to check valve obstruction of the trachea on the 4th postoperative day. A nebulizer provided continuous moisture and was effective in preventing recurrence of the crust attachment to the tracheal membrane thus, the tracheostoma was closed by the 17th postoperative day. This case indicates that among healthy people there are extremely rare patients with congenital tracheal stenosis who survive their postnatal and infantile periods, and who experience no trouble in their daily lives. As physicians, we must be aware of this disease in adult patients in our clinics.

Subglottic hemangioma (SGH) is a benign neoplasm that may cause severe and life-threatening respiratory obstruction in infants. However, patients usually present with inspiratory stridor in the first few months of life and may be mistakenly diagnosed as recurrent or persistent croup. Definitive diagnosis is made by image studies, endoscopic examination and biopsy or all. We report a 2-month-old female infant of SGH with initial clinical manifestations of dyspnea and inspiratory stridor co-existing with cutaneous and cerebellar hemangiomas. Clinicians must be alert the possibility of SGH when associated with cutaneous hemangioma. This patient has received oral steroid treatment for more than two months with improvement of the airway obstruction. Although purplish patch lesions over left side of face, eyelid, cheek, and peri-oral regions regressed, the size of the SGH on the followed MRI was slightly enlarged. The diagnosis and various treatments of SGH are discussed and reviewed in this paper.

Kaposiform hemangioendothelioma is a rare pediatric neoplasm that presents most commonly in the soft tissues. We report the case of a 1-month-old infant who presented with stridor and was found to have a diffusely infiltrating tumor in the thymus that extended into the pericardium and up the carotid sheaths. Histologic examination revealed a vascular tumor infiltrating among the lobules of the lymphocyte-depleted thymus. The lesion had features of both a capillary hemangioma and Kaposi sarcoma. Immunoperoxidase studies on formalin-fixed, paraffin-embedded tissue demonstrated the neoplastic endothelial cells to be positive for vascular markers CD31 and CD34. Antibody to factor VIII-related antigen labeled feeding vessels, but failed to stain the lobules of tumor. Although these tumors have been treated in a fashion similar to capillary hemangiomas in the past, it may be important to differentiate Kaposiform hemangioendotheliomas because of their association with Kasabach-Merritt syndrome and recent success with more aggressive chemotherapy regimens.

A 45-year-old mentally retarded woman was discovered to produce a stridor upon inhalation. Fiberoptic laryngoscopic study revealed a smooth-surfaced, wide, and pedunculated tumor on the right arytenoid and the right aryepiglottic fold. Histopathological study revealed that the tumor was characterized by granulomatous inflammation. The condition was diagnosed as laryngeal sarcoidosis. The tumor was resected surgically. Surgical resection of the tumor and injection of corticosteroid should be performed for polypoid-type laryngeal sarcoidosis. The case is discussed in detail, along with a review of the literature pertaining to sarcoidosis of the larynx.

The intratracheal goiter is a rare, benign disease accompanied by dyspnoea, stridor, and cough. The specific symptom within the non-specific symptoms is the rapid therapy-resistant progression that can be fatal if it is unrecognized and not treated. Observation of an intratracheal tumor leads to a series of further differential diagnostic considerations with the most important question--malignant or benign--which needs to be clarified. The type of tissue can be determined by means of a biopsy. Classification of the grade of the tissue is not possible in every case and always depends on the method used. This is especially true in the case of highly differentiated tumors as they appear on the thyroid. We introduce a 67-year-old female patient whose case history and results can be described as classic in comparison to the literature and who showed all the clinical and morphological characteristics of intratracheal goiter. We refer to the two most possible theories concerning the etiology. Extirpation of the tumor with or without a temporary tracheostomy is the suitable therapy for adults to achieve functionally indisputable results without recurrence. Knowledge about these rare intratracheal tumors can help avoid a generous resection with high risks or even foreseeable consequences.

A 56-year-old man, at one year before his first visit to our hospital, had presented cough, stridor and chest pain, and expectorated a mass, resulting in prompt disappearance of the symptoms. He was afflicted with recurrent symptoms, and the bronchoscopy showed a polypoid tumor occluding the right lower bronchus. The tumor was resected via bronchoscopy, which revealed histologically small cell carcinoma with significant inflammation and scar formation. The tumor was macroscopically the same as the one that had been expectorated by the patient at one year previously. A right lower lobectomy was conducted, but the specimen demonstrated no residual tumor. Tumor invasion into the bronchial wall was therefore limited within the submucosal layer for more than a year. Finally, the present tumor was diagnosed as an early small cell lung cancer with a characteristic of self involution. With no adjuvant treatment, the patient is well without tumor recurrence at 3 years to date after the surgery.

A 56-year-old Japanese male with persistent cough, stridor and diffuse wheezing for 6 months had obstructive pulmonary dysfunction and airway hyperresponsiveness (AHR) to inhaled methacholine. Because of a poor response to glucocorticoid therapy and neutrophilia in the peripheral blood and sputum, chest computed tomography was performed and a plate-like tumor in the truncus intermedius was identified. Fiberoptic bronchoscopy demonstrated a plate-like green-colored tumor firmly impacted into the truncus intermedius and diffuse inflammatory changes spreading to both main bronchi. A piece of 'kombu' (Japanese kelp) was successfully removed by fiberoptic bronchoscopy under general anesthesia. Pulmonary function and methacholine inhalation tests became normal after the removal of the foreign body. In this case, it is suggested that asthma-like symptoms were due to localized airflow limitation in the right bronchus as well as to AHR associated with diffuse airway neutrophilic inflammation.

A case of an adenoid cystic carcinoma of trachea is presented. A 30-year-old non-smoking woman with strong inspiratory dyspnea at rest was admitted to the Dept. of Pulmonary Diseases. At auscultation a respiratory murmur was more silent at right lung and stridor over trachea was heard. CT scan revealed tumor at the bifurcation of the trachea. Bronchoscopy was made and biopsy established the diagnosis: adenoid cystic carcinoma. The tumor was partially removed with rigid bronchoscope and radiotherapy was started. Clinical improvement occurred; in control CT scan tumor vanished. The trachea cancers are rare. Symptoms often mimic asthma or chronic bronchitis. Thus in every patient with chronic cough and dyspnea bronchoscopy should be made. A treatment of choice is primary resection and postoperative radiotherapy.

Cartilaginous tumors of the larynx represent less than 1% of laryngeal tumors. Chondroma and "low-grade" chondrosarcoma are the most common; 70%-75% of these tumors arise on the endolaryngeal surface of the posterior lamina of the cricoid cartilage. The clinical presentation is varied and directly dependent on the size and location of the tumor; stridor, hoarseness, dyspnea, or a neck mass are common presenting signs. CT scanning in the axial plane is the mainstay of radiographic imaging due to its ability to show size, extent of the tumor, and invasion into surrounding structures. Surgical extirpation is the standard therapy with no role for radiation therapy or chemotherapy. Although significant recurrence rates have been reported, there is not a significant difference between initial conservative therapy followed by salvage therapy versus initial radical therapy.
