Sarcomatoid carcinoma is a rare and occurs mainly in the upper aerodigestive tract such as the oral cavity, esophagus and vocal cords. It is a unique variant of squamous cell carcinoma. We report the case of a patient with spindle cell squamous cell carcinoma involving the mandible. At initial examination, overlying mucosa of that lesion was normal appearance. One week later, that lesion showed ulcerative and bloody change and rapid growth in size. This case showed unpredictable rapid growth although rapid growth in size was suspected of undergoing malignancy.

Extramedullary plasmacytoma is extremely rare, constitute 3 to 5 % of plasma cell malignancies and commonly occur in the upper aerodigestive tract. Several case studies of extramedullary plasmacytoma occurring in unusual location are reported; stomach, bladder, central nervous system, breast, thyroid, testis, salivary gland and skin. Here, we present a case of an extramedullary plasmacytoma of the right gluteus maximus muscle in a 49-year-old man.

Seven patients having midline granuloma received local irradiation from March 1983 to June 1986. Clinically, all of the 7 patients had pansinusitis with necrotic destruction of the involved sites and one case revealed colonic lesion. Each of the patients received a tumor dose of $4,000\~5,000 cGy/5\~6$ wks to the upper aerodigestive tract using a 6-MV linear accelerator. Complete and partial remission occured in 3 patients each, and in one case, the disease progressed despite of the irradiation.

Foreign body (FB) ingestion is commonly seen in the ear nose and throat (ENT) field, with different presentations and sequelae. FBs can arrest in the upper aerodigestive tract or continue further down into either the airway tract to the bronchus or the digestive tract to the intestines. The pathway of an FB depends on the size and shape of the FB and how sharp its edges are. Since the 20th century, the use of disposable stainless-steel needles in the oral cavity has proven to be an effective and safe method for performing various intraoral procedures like dental infiltration or a root canal wash. Complications from their use are rare. Generally, dental needle breakages are caused by patients biting the needle, incorrect injection techniques, or inadequate preventative measures. The sudden movement of a patient during a procedure is one of the most common causes of breakage. Occasionally, needles are swallowed during dental procedures such as a root canal. Here, we report a case of a patient that swallowed a broken needle during a dental procedure. A few days later, the patient presented with neck pain, swelling, and a FB sensation. When the patient presented, she claimed that her symptoms had onset after consuming a meal containing duck meat. Initially, the patient was diagnosed as having ingested a duck bone. However, intraoperatively, the FB was discovered to be an injection needle that had migrated from the throat to the neck.

The detection of foreign bodies in the upper-aerodigestive tract is a fairly frequent event and can occur in various areas and for various reasons. In rare cases, foreign bodies can simulate a neoplasia. We evaluated similar cases during emergency regimen with an oral cavity mucosal lesion, causing lockjaw, sore throat, dysphagia, and swelling of the submandibular and laterocervical region. Physical examination revealed an extensive mucosal ulceration in the floor of the mouth and the lateral surface of the tongue, comparable to oral cancer. During a second, more accurate assessment, a partially deteriorated iron supplement tablet was found embedded in a mucosal pocket. After removing the tablet, gradual normalization of the tissue was observed without any sequelae. This is one of the many reasons why it is advisable and useful in cases of oral lesions to collect a detailed medical history and to perform an accurate clinical evaluation, including inspection and palpation of the lesion, before proceeding to further diagnostic assessments, especially in elderly patients taking many medications. However unlikely, it is possible that difficulty in swallowing pills or tablets could generate tumorlike lesions.

Basaloid squamous cell carcinoma(BSCC) is uncommon and distinct variant of squamous cell carcinoma that arises mostly in the upper aerodigestive tract and aggressive, high grade tumor with an increased tendency to be deeply invasive, multifocal, and metastatic even at the initial presentation. The typical microscopic features of carcinoma with a basaloid pattern in intimate association with a squamous component helps in diagnosis of this tumour. Since Wain's report in 1986, BSCC of oral cavity, the palate, floor of the mouth, nasopharynx, oropharynx and mastoid region have been reported. However, BSCC in the nasal cavity or in the paranasal sinuses is rare and there are few reports in the Korean literature. We had experienced a case of basaloid squamous cell carcinoma that occurred in the left maxillary sinus of 72-year-old woman and reported with review of the clinical and pathologic features from the literature.

Laryngeal neoplasm is the second most common malignancy of the upper aerodigestive tract. About 85% to 95% of laryngeal malignancies are squamous cell carcinoma that arises from the epithelial lining of the larynx. The exact cause of laryngeal neoplasm is unknown, but certain risk factors can affect the chances of developing it. Chronic inflammation is a mutagen factor confirmed in the carcinogenesis of various tumor. Inhalation injuries cause histopathologic damage to laryngeal mucosa and inflammation change. This long term inflammation may leads to the development of dysplasia and malignant transformation. Recently, we experienced a case of malignant transformation of laryngeal mucosa after inhalation injury patient 25 years ago. Herein, we reported this rare case and review the relevant literature.

Caustic bums of the upper aerodigestive tract continue to be a significant clinical problem. Wide -field pharyngoesophagectomy is commonly performed as treatment for malignancies of the hypopharynx. A total laryngectomy is often necessary at the time of this procedure because of the anatomical proximity of the cancer or because of the likely compromise of swallowing postoperatively. When preservation of the larynx is attempted, aspirations after surgery frequently require a second-stage laryngectomy. And various flaps are using for reconstruction of esophageal defect. The choice of reconstruction is depended to the patient's status. A 54-year-old women whose symptom was severe dysphagia and X-ray revealed laryngopharyngeal stricuture. She had attempted suicide by swallowing lye liquids 32 years ago. She has entire laryngopharyngeal and esophageal stricutures. Total laryngectomy was performed and reconstruction of theesophagus was carried out with unusual reversed-gastric tube formation. Hence, we report this case with the review of literaturefor proper management in the future.

Granuloma is an uncommon benign disease that develops in the process of wound healing. Pharyngeal or laryngeal granuloma can be associated with gastric reflux, mechanical injury or trauma including intubation, voice abuse, or foreign body. 50-year-old female was transferred to our institute with a huge mass occupying the upper aerodigestive tract causing dysphagia. The patient has been suffering from a brain hemorrhage for several months and was kept in bed due to the quadriplegia with stuporous mental status, and was tracheotomized. On examination, the whole oropharynx and hypopharynx was covered by a smooth-surfaced soft big diffuse granular mass, which extended down to the upper trachea through the larynx. The huge granuloma was successfully removed with surgery and was found to have a pedunculating stalk on the oropharyngeal posterior wall with a small mucosal defect, suggestive of the origin of the mass. The defect was closed primarily after the cauterization. The patient is now followed up regularly without any recurrence of the disease.

Basalold squamous carcinoma (BSC) is a rare, aggressive neoplasm of the upper aerodigestive tract or esophagus. It is characterized by a biphasic pattern in which basaloid tumor is intimately associated with a neoplastic squamous component which can be either Invasive r in situ. Despite its characteristic histologic appearance, the BSC of the esophagus has been confused with esophageal neoplasm variously reported as adenoid cystic carcinoma or carcinoma with adenoid cystic differentiation Their distinction is important because genuine adenoid cystic carcinoma is much less as- gressive than BSC. The biologic course of BSC is similar to that of the more frequent squamous cell carcinoma of the esophagus. We have experienced a case of BSC of the esophagus in a 60-year-old male patient. The lesion was located in the middle third of the esophagus. The patient was treated with surgery followed by radio- therapy.
