Ectomesenchymal chondromyxoid tumor is a rare benign tumor. It occurs uniquely on the oral cavity particularly the tongue. It was first described in 1995, and only 36 cases were reported in the literature. We report a case of ectomesenchymal chondromyxoid tumor in a 67-years-old male, who presented with an asymptomatic, firm, round shaped mass on the dorsum of the tongue. The lesion was completely excised and confirmed as ectomesenchymal chondromyxoid tumor on histopathological examination.

The fibromatoses are defined as a group of non encapsulated, non metastasizing, fibrous tumors that have a tendency for infiltrative growth and local recurrence following surgical excision and can be divided into fascial and musculoaponeurotic fibromatoses. Infantile fibromatosis is childhood counterpart of musculoaponeurotic fibromatosis and is more common in the head and neck, the shoulder and upper arm and the thigh. Treatment includes excision, radiation, steroid and chemotheraphy, etc. Treatment of choice is complete excision but postoperative deformity and sequelae should be considered. Recently, we have experienced a case of infantile fibromatosis originating from infratemporal fossa and report this case with a review of literatures.

Benign lymphoepithelial cysts of parotid gland were first described by Miculicz in 1888, have been presented for a long time, uncommonly. But, recently it has been reported with increasing frequency since the onset of human immunodeficiency virus (HIV) infection. Benign lymphoepithelial cysts can be diagnosed by the fine needle aspiration in conjunction with the history and physical examination. The therapeutic options of benign lymphoepithelial cysts have been limited to aspiration, surgical resection, medical therapy, radiotherapy and sclerotherapy. Recently, we experienced a case of benign lymphoepithelial cyst of right parotid gland, so we report this case with review of the literatures.

Mucoepidermoid carcinoma is most frequent malignant tumor of parotid gland. However, mucoepidermoid carcinoma arising from pleomorphic adenoma has been disputed and rarely reported. 54-year-old woman with pleomorphic adenoma underwent superficial parotidectomy. And 15 years later, she diagnosed mucoepidermoid carcinoma at the same side. We report the case with a review of literature.

본방사선 치료 후에 후두 절제술을 시행할 경우 인두피부누공, 감염, 출혈 등 상처부위 합병증의 가능성이 높다. 저자들은 최근에 항암치료와 방사선 치료 후에 재발한 성문상부암에 대해 후두 전적출술을 시행하였고, 수술 66일째 생명을 위협하는 인두의 동맥 출혈을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Carcinosarcoma of the parotid gland is extremely uncommon and is known to be an aggressive malignant mixed tumor in which carcinomatous and sarcomatous elements coexist and metastasize together. We report a case of recurrent parotid gland carcinosarcoma that showed squamous cell carcinoma and chondrosarcoma in a 58-year-old woman.

Myoepithelioma is composed predominantly or exclusively of myoepithelial cells. It is most frequently located in parotid gland, the palate and the breasts. It accounts for less than l% of all salivary gland tumors. Surgical excision which accompany a marginal amount of uninvolved tissue is curative. We report a case of parotid gland myoepithelioma treated by surgery.

Epidermal cysts in mouth floor are rare. There could be confusions in diagnosis due to location and low incidence. For diagnosis, imaging study and cytology are necessary. The treatment of choice is complete excision intraorally or externally and the recurrence is rare. Some authors prefer sclerotherapy, but the follow up is necessary for malignant change. We report two cases of epidermoid cyst in submental area excised externally with literature review.

Pleomorphic adenoma is the most common benign mixed salivary gland neoplasm that accounts for 65% of all benign salivary glands tumors. While the majority arises from the parotid, only a 10% arises from the minor salivary glands. Pleomorphic adenoma of minor salivary gland in the palate is a common entity. However, they occur in the lip, cheek, tongue oropharynx and nasal cavity etc., rarely. We experienced a case of a 80 years old female presented a 10 years history of a right cheek mass which was proved to the pleomorphic adenoma on the histopathologic examination. We resected the mass and obtained good postoperative results. We report this case with a review of literature.

Thyroid cancer is known as its relatively high cure rate after surgical treatment and spinal metastasis of thyroid cancer is extremely rare as the prevalence is only 2-13%. Spinal metastasis is usually asymptomatic and discovered incidentally in most cases. A 66-year-old man was diagnosed as thyroid papillary cancer with spinal metastasis. We treated the patient by surgery, adjuvant radiotheraphy and radioactive iodine therapy. C6 corpectomy was followed for the residual spinal metastasis by the department of neurosurgery. The patient had no functional complication by the surgical process. At 24 months after surgery, there was no sign of recurrence and the patient led social life without any discomfort. We present this case with a review of the related literatures.
