A retrospective analysis was performed on 55 patients with malignant parotid tumor who were treated with radiation therapy between March, 1979 and July, 1989. Of these patients, 8 patients received radiation therapy(RT) alone and 47 patients were treated with combined operation and radiation therapy(OP + RT). The follow-up period of the survivors ranged from 1 to 129 months with a median of 48 months. The common histologic types were mucoepidermoid carcinoma (25 cases), malignant mixed tumor(12 cases), adenoid cystic carcinoma(6 cases). The 5 and 10 year local control rate were 69.8% and 65.7% in all patients. In OP+RT group, prognostic factors related to local control were histologic grade, tumor size, lymph node metastasis. Resection of facial nerve did not affect the local control rate significantly(p=0.129). Distant metastasis developed in 23.6% of patients, mostly to the lung. Actuarial overall survival rate was 72.2% at 10 years and formed plateau after 5 years. Disease-free (NED) survival rate was 49.4% at 10 years and was better achieved in OP+RT group and low grade lesions. Based on our result, a well planned postoperative RT following parotidectomy is highly efficacious in controlling malignant tumors of the parotid gland and preservation of facial nerve.

Small cell carcinoma is mainly found in the lungs and extrapulmonary origins of small cell carcinoma in GI tract, head and neck, genitourinary system consists only 4% of the tumor. Thus, small cell carcinoma of the parotid gland is an extremely rare disease. Extrapulmonary small cell carcinoma is characterized by an aggressive clinical course with early metastasis. We report a case of small cell carcinoma of parotid gland in a 82-year-old woman with painless neck mass, who was managed with radiation therapy after surgery and review of relevant literatures.

Squamous cell carcinoma, which is a common primary head and neck malignant neoplasm that is usually restricted to the mucosal surfaces of the upper aerodigestive tract and skin, is very unusual in the major salivary gland. Among them, few cases are regarded as primary carcinomas. In this article, we present two cases of squamous cell carcinoma in the parotid gland, who first presented with painful mass on infraauricular area.

Lymphadenoma is a rare benign neoplasm of the salivary gland. Herein, we present a 67-year old woman with lymphadenoma in the parotid gland. Physical and radiologic examinations of parotid lymphadenoma are not specific and preoperative diagnosis is usually difficult. Therefore, clinicians should consider the possibility that lymphadenoma may occur in the parotid gland mimicking the other more frequently observed lesions.

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.

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.

Primary non-Hodgkin's lymphoma of the salivary gland is an uncommon tumor that most often occurs in the parotid gland. In the parotid gland, malignant lymphomas are often clinically unsuspected, manifesting as nonspecific mass indistinguishable from other more common epithelial tumors. This case report describes a bilateral parotid glands mass as a first symptom of non-Hodgkin's lymphoma. The final diagnosis was established after an excisional biopsy and immunohistochemical staining. The patient underwent surgical excision and chemotherapy.

We have reviewed a 9-year experience with 47 patients treated for salivary tumors which arose In the parotid gland (23 patients; 48.9%), submandibular gland (15 Patients, 31.9%), minor salivary gland (8 patients; 17.0%), and sublingual gland (1 patient; 2.1%). The age of patients ranged from 12 to 71 with a mean of 42.9 years. The male to female ratio showed a female preponderance, 19:28 (1:1.5). An asymptomatic mass (91.5%) was most common presentation. With fine-needle aspiration, the predictive value of a neoplasm was 88.9%. Histopathologically, the most common salivary gland tumors was Pleomorphic adenoma(57.4%). The pleomorphic adenoma was most common in benign tumor group, and the mucoepidermoid carcinoma was most common in malignant tumor group. Of the salivary gland tumors, the incidence of cervical metastasis was 22.2%. Major postoperative complications were facial nerve paralysis and wound infection.

타액선 병변의 일반적인 영상진단법으로는 타액선조영술, 전산화단층촬영술, 자기공명 영상, 타액선 스캔, 초음파 촬영술이 있다. 이중 초음파촬영술은 타액선내 종양의 유무를 평가하는데 있어서 매우 우수하여, 전산화단층촬영이나 자기공명영상과 더불어 이용되고 있으나, 염증을 진단하는데 있어서는 타액선조영술보다 민감도가 떨어지는 단점이 있다. 일반적으로 타액선의 염증반응시 초음파상은 반향이 정상보다 낮아지며, 내부의 균질성이 떨어지는 양상을 보여 이를 진단의 기준으로 이용해왔으나 정상타액선에서도 반향이 편차가 심할 뿐만 아니라 연령에 따른 정상 타액선의 반향성에 대한 연구가 부족하여 진단에 어려움이 있었다. 이에 저자는 우선적으로 타액선에 병적인 증상이 없는 남녀 90명을 연령별(20-35세 : 청년군, 36~55세 : 중년군, 55-70세 노년군),성별에 따라 분류하여 정상 타액선의 초음파상을 얻었다. 이의 반향을 측정하고, 비만한 정도를 나타내는 체격지수를 구하여 다음과 같은 결과를 얻었다. 1. 이하선과 악하선 모두에서 연령군극_ 따라 반향성이 증가하는 양상을 보였으며, 청년군과 노년군 사이에는 유의한 차이가 있었다(p<0.05). 2. 이하선과 악하선 모두에서 성에 따른 반향성의 유의한 차이는 없었다. 3. 성에 관계없이 악하선의 반향성이 이하선의 반향성보다 높았으며, 남자에 있어서는 유의한 차이가 있었다(p<0.05). 4. 동일한 타액선에서 좌우측 타액선의 반향성의 평균 차이값은 유의한 차이가 없었다. 5. 이하선과 악하선의 반향성은 중등도의 양의 상관관계를 보였다(남자 : r=0.56, 여자 : r=0.54). 6. 체격지수와 타액선의 반향성은 약한 양의 상관관계를 보였다.
