Warfarin sodium is a widely used oral anticoagulant and it sometimes causes hemorrhage in various sites such as traumatic or operative wounds, urologic organs, gastrointesitnal tract and subcutaneous tissues. Warfarin induced hemorrhage in upper respiratory tract causing upper airway obstruction is extremely rare. Despite the life-threatening nature of this complication, the symptoms are obscure like sore throat or hoarseness, suggesting infection and early diagnosis can be delayed. Careful medical history is emphasized When bleeding is observed, the patient should be admitted for close observation and prompt treatment. Recently we have exrperienced a case of laryngeal and upper tracheal submucosal hemorrhage induced by long term warfarin in 64 years old mm. We described the case with a review of the literature.

Pyogenic granuloma is very uncommon disease. It is a benign, elevated, and capillary-rich lesion occupying on the skin and mucous membranes, and is a reactive lesion, an overgrowth of granulation tissue. And this lesion may grow rapidly and can recur frequently. Pyogenic granuloma usually occurs on the lip, tongue, oral mucosa, and nasal mucosa. But, pyogenic granuloma of vocal cords is very rare. Recently, we experienced a case of pyogenic granuloma of a 48-year-old man who had been presented with hoarseness for 3 months. He was diagnosed pyogenic granuloma after laryngeal microscopic surgery. So we report this rare case with review of literatures.

Neurofibromatosis type II is an autosomal dominant, highly penetrant disease whose hallmark is bilateral vestibular schwannoma. Hearing loss is the most symptom in Neurofibromatosis type II. The patient can also present with tinnitus, disequilibrium, and headache. Cranial nerve symptoms, such as facial numbness or weakness, dysphagia, or hoarseness, can also be present. The authors experienced a case of neurofibromatosis type II having huge retropharyngeal mass, retropharyngeal abscess, and bilateral acoustic neuromas. The infection was controled with aggressive antibiotics with drainage. The huge neurilemmoma in retropharyngeal space was removed successfully via transoral approach. The authors report the case with literature review.

Stellate ganglion block is extensively performed in pain closing to treat a diversity of diseases. Stellate ganglion phenol neurolysis, however, has not been not popular because of risk and complications such as: permanent horner's syndrome, hoarseness, pneumothorax and intravascular or intraspinal injection. But Racz recently performed stellate ganglion phenol neurolysis successfully, under fluoroscopic guide, minus significant complication. Three patients were recently treated at our pain clinic by repeated stellate ganglion block with local anesthetics. Patients showed immediate signs of improvement but prolonged pain relief was not achieved. Therefore we reported to performing stellate ganglion phenol neurolysis following Racz's technique. We successfully treated: two cases of reflex sympathetic dystrophy of the upper extremity, and a case of postherpetic neuralgia of jaw, neck and upper chest wall, by stellate ganglion phenol neurolysis, devoid of any significant complications.

Rhabdomyosarcomas are relatively rare and highly malignant tumors which originated from mesenchymal cells. A 50-year-old man, suffered from hoarseness for 2 months, visited to the Dept. of ENT, Seoul Red Cross Hospital. By indirect laryngoscopic examination, a sessile based whitish polypoid mass (0.5cm$\times$0.3cm) was noted at the one third portion of right true vocal cord. Under general anesthesia, local excision was performed. Biopsy revealed rhabdomyosarcoma of the embryonal type. To our knowledge, only 24 cases of laryngeal rhabdomyosarcoma have been reported in the world literature.

This paper is a review of 29 cases of mediastinal tumors originating in the mediastinum or metastasized from other organs and classified on the basis of histopathological types and specific anatomic location in this depart-ment, during nine years period from January 1959 to December 1967. In twenty-three cases, diagnosis was confirmed by histological findings and the rest of the cases were considered to be mediastinal tumors by clinical and/or roentgenological findings. In this series, metastatic mediastinal carcinomas of unknown primary site were most frequent [30.4%] and lymphoma ranked second in frequency comprising 21.7% of total. Range of age was 5 to 61 years and average mean age was 39 years old. Sex ratio was 1.4 male to female. Subjective complaints in order of frequency were as follows: dyspnea [37%], cough [34%], chest pain[24%] and chest discomfort [21%]. Objective signs were as follows: hoarseness [17%], palpable cervical lymph node[17%], blood tinged sputum [10%], weight loss [10%] and superior vena cava syndrome [7%]. There was no operative mortality. There were histologically nine different kinds of mediasfinal tumors in this series.

We have experienced 2 cases vocal cord paralysis after open heart surgery. One was a postoperatively developed right unilateral vocal cord paralysis after prosthetic mitral valve replacement with tricuspid valve annuloplasty. The other was a postoperative left unilateral vocal cord paralysis after prosthetic aortic and mitral valve replacement with tricuspid annuloplasty. They were intubated for forty-eight and seventy-two hours but after extubation complained of hoarseness, aphonia, anxiety, and ineffective coughing Indirect laryngoscopy performed at about postoperative one week, revealed partial paralysis and decreased mobility of the vocal cord. After active phonation therapy, symptoms were improved gradually and in the follow up indirect laryngoscopy, the vocal cord paralysis was improved. The symptoms were recovered completely at about postoperative one month in both. The cause of vocal cord paralysis after open heart surgery may be any retraction or stretching injury to the recurrent laryngeal nerve, especially right side, during median sternotomy retraction and open heart operation procedures. As a result, avoid of excessive spread of median sternotomy retractor and excessive manipulation and retraction of the heart during open heart procedures will reduce the occurrence of the vocal cord paralysis.

Unilateral vocal cord paralysis occurs from a dysfunction of the recurrent laryngeal nerve. It causes a characteristic hoarseness, shortness of breath and swallowing disability. Prompt injection laryngoplasty is a treatment options that aims to improve these symptoms less invasively and easily than any other procedures. Cross-linked hyaluronic acid (HA) is widely used injection material. It is non-mammalian polysaccharides derived from streptococcus strain and well known for its duration in vocal cord about 3-6 months after injection. However, there were no complication reports such as infection or rejection after HA injection laryngoplasty in previous report. We present a case of patient with laryngeal abscess after transcricothyroid membrane percutaneous HA injection laryngoplasty.

Relapsing polychondritis is a rare disesase involving any cartilaginous structure of entire body and is characterized by recurrent episode of inflammation and degeneration of cartilage and most commonly involve ear, nose, larynx, trachea, ribs, Eustachian tube, etc. Its signs and symptoms are recurrent swelling of auricle, saddle nose deformity, polyarthralgia, hoarseness and dyspnea, audiovestibular disturbance and cardiovascular abnormality, etc. Characteristic histologic findings are loss of normal basophilic staining of cartilage, perichondrial inflammatory infiltration with plamsa cells, lymphocytes and neutrophils, and finality, destruction of cartilage and replacement with scar tissue. Our case had saddle nose deformity, arthralgia, tracheal collapse, hearig loss and positive histologic finding but no auricular perichnodritis. Her major problem was airway. obstruction due to tracheal collapse. This case was diagnosed with relapsing polychondritis according to the Damiani's criteria. This case indicates that any patients complaining of airway obstruction have to be examined systemically.

Primary laryngeal candidiasis is rare in immunocompetent patients and is prone to confusion with early glottic carcinoma or leukemia. We experienced a case of 74-year-old man who has 3- month history of hoarseness. The pathologic diagnosis was laryngeal candidiasis. He was treated with antifungal agents for 4 weeks after vocal cord stripping under general anesthesia. After treatment, the patient had no candidiasis or discomfort with his voice. We report this case with a review of literature.
