The Spindle cell lipoma is a slow-growing benign tumor seen generally in the shoulders, upper back, and back of the neck of male. The Pleomorphic (giant-cell) lipoma is a benign tumor of adipose tissue with atypical histological features. It is mainly seen in the same lesion as the Spindle cell lipoma. The Pleomorphic lipoma is cytogenetically similar to spindle cell lipoma with a consistent loss of chromosome 16q material. For this reason, these two entities are regarded as a similar spectrum in the adipose tumors. Herein, we present a 53-year old man with Spindle cell/pleomorphic lipoma in the lateral neck. Physical and radiologic examinations of the Spindle cell/pleomorphic lipoma in the lateral neck are not specific and preoperative diagnosis is usually difficult. Therefore, clinicians should consider the possibility that Spindle cell/pleomorphic lipoma may occur in the lateral neck mimicking the other more frequently observed lesions.

The differential diagnosis of lesions in buccal area include lipoma, neurofibromas, epidermoid cyst, salivary ducts calculus, hemangioma, lymphadenopathy. Accessory parotid glands is defined as salivary gland tissue adjacent to the parotid duct, but separated from the body of parotid and it may be found in approximately 20% of human parotid glands. The appearance of an accessory parotid tumor is rare, with a reported frequency of 7.7% of all parotid neoplasm. Angiomyoma, which is also termed angioleiomyoma, is a rare solitary subcutaneous tumors arising from the vascular smooth muscle. It often occur in the extremities and is rarely found in buccal area. We present 2 cases of rare tumor in buccal mass and resected surgically without facial nerve palsy.

Background and Objectives： Primary benign masses in subglottis and trachea are rare. Symptoms of tracheal obstruction are similar to those of bronchial asthma, chronic bronchitis, as well as malignant lesions. Materials and Methods： Eight patients with benign tracheal masses from April 1992 through June 2001, at otolaryngology-head and neck surgery. department of Seoul national university hospital were studied by retrospective medical record review. Results : They were 3 females and 5 males aged from 0 to 57 years. The pathologies of the intratracheal masses were lipoma. tuberculosis, pleomorphic adenoma, hemangioma(two case), reparative giant cell granuloma, epithelial inclusion cyst and nonspecific lymphadenopathy, respectively. The most characteristic symptoms were dyspnea and stridor, both inspiratory and expiratory. Five of them had been treated as bronchial asthma. Conclusion： For the management of patients with the subglottis and tracheal masses, it is important to establish secure airway. regardless of pathology of the masses. The diagnosis should be considered in any patient with asthma-like manifestation, especially who fails to respond to medical treatment. It is necessary to examine the airway thoroughly, and chest and simple cervical X-ray may contribute to the diagnosis of possible intratracheal mass.

영남대학교 의과대학 부속병원 안과에서 1984년 3월부터 1994년 8월까지 병리조직검사로 확인된 안와종양 95례를 대상으로 임상적 고찰을 실시하였다. 안와종양의 발생빈도는 성별로는 남자가 46명(48.4%), 여성이 49명(51.6%)으로서 유의한 차이를 보이지 않았으며, 연령분포는 양성종양의 경우 전 연령층에 걸쳐 고루 분포하였고, 악성종양의 경우 10세 미만과 50-60대에 특히 많은 발생을 보였다. 광학 현미경으로 살펴본 병리조직학적 검사상 양성 대 악성의 비율은 82% : 18%로서 다른 연구에서 보다 양성종양의 비율이 높았다. 종류별로는 피부지방종(20례, 21%), 유피낭(11례, 11.6%), 점액류(8례, 8.4%), 지방종(7례, 7.4%), 다형생 선종(5례, 5.3%) 순이었다. 양성종양은 성인의 경우 점액류, 유피낭, 다형성 선종, 해면혈관종 순의 발생빈도를 보였고, 소아의 경우 피부지방종, 유피낭, 지방종, 망막모세포종 순의 발생빈도를 보였다. 악성종양은 망막모세포종 3례, 악성 흑색종 2례, 피지선암 2례, 상악동암 2례 등이었다. 악성종양중 사망한 경우는 17례 중 8례 (47.0%)로서 모두 이차성 혹은 전이성 안와종양이었다.
