  • Myoepithelioma is histologically composed exclusively of myoepithelial cells. Myoepithelial cells are present in the major and minor salivary glands. Salivary gland neoplasms that frequently contain myoepithelial cells are the pleomorphic adenoma, adenoid-cystic carcinoma, and epithelial myoepithelial carcinoma of intercalated duct origin. Neoplasms composed exclusively of myoepithelial cells are rare. Myoepitheliomas may be composed of spindle-shaped cells, plasmacytoid(hyaline) cells, or combination of both in varying proportions. A case is reported of plasmacytoid myoepithelioma with ultrastructural confirmation, together with reviews of the English literature.

  • Necrotizing sialometaplasia (NS) was defined by Abrams et al. in 1973 as a reactive necrotizing inflammatory process involving minor salivary glands of the hard palate. Before that recognition, many patients with this condition had been improperly treated because of its clinical and histologic resemblance to malignancy such as mucoepidermoid carcinoma and squamous cell carcinoma. We report two cases of necrotizing sialometaplasia. One case involved a 58-year-old male who had an ulcerative palatal lesion exposing underlying bone which has the typical features of the above mentioned condition. Another case involved a 59-year-old male who developed a necrotizing sialometaplasia in association with a dome-shaped palatal swelling which was proved as an adenoid cystic carcinoma after operation biopsy.

  • Basal cell tumors from 53 dogs were examined histologically and classified as basal cell adenoma(n=44), granular basal cell adenoma(n=1), basal cell carcinoma(n=3), basosquamous cell adenoma(n=1), basosquamous carcinoma(n=4) on the basis of malignancy and squamous metaplasia. Female was twenty three and male was thirty. Affected dogs are usually 5.6 years and sex predilection have not been seen. None of tumor examined was metastasized into other organs. Distinct patterns identified in the basal cell adenoma are solid(n=15), cystic(n=13), adenoid(n=8), medusa(n=5) and ribbon(n=3). Solid basal cell adenoma is common type in benign basal cell adenoma. Only one neoplasm was granular basal cell adenoma which was characterized by eccentric nucleus and abundant granular cytoplasm. Basal cell carcinoma showed anaplastic appearance histologically and had atypical basaloid epithelial cells and multinucleated giant cells with moderate number of mitotic figures. Both basosquamous cell adenoma and carcinoma had squamous metaplasia.

  • Thirteen patients with lung cancer have undergone bronchoplastic procedures from January 1991 to July 1994 in Kyung Hee univ. Hospital.Among them,twelve patients were male and one patient was female from 33 to 76 years of age.[ mean 56.6 11.5 years of age The pathologic diagnoses were squamous cell carcinoma in twelve patients and adenoid cystic carcinoma in one patient.The bronchoplastic procedures consisted of seven right upper sleeve lobectomies, one right middle sleeve lobectomy, one left lower sleeve lobectomy and four sleeve pneumonectomies. In these sleeve pneumonectomies, right sleeve pneumonectomy was done in three patients and the other was left sleeve pneumonectomy. Including the four sleeve pneumonectomies, carinoplasty was performed in seven patients. Postoperatively, we carried out bronchoscopic suction of intrabronchial secretions in necessary for the prevention of postoperative complication. All except one were discharged without any complication and have been in good condition. Postoperative mortality was in one patient who expired 25days after right middle sleeve lobectomy with respiratory failure.

  • 비강(nasal cavity)파 인두(pharynx)의 주기능의 하나는 상기도(upper respiratory tract) 로서 전비공(anterior nares)을 통해서 들이 마신 공기를 하기도(lower respiratory tract)로 통과시키는 기능이다. 일반적으로 홉기가 전비공에서 후비공(choana)으로 직선으로 통과하지 않고, 전비공에서 흡입된 공기는 후상방으로 높이 올라가 곡선으로 후열(olfactory fissure)을 향하여 후비공쪽으로 지나간다. 그러나 해부학적인 이상 즉, 비후된 비갑개 (turbinate), 아데노이드증식증(adenoid hyperplasia), 비중격만곡(deviation of the nasal septum)등의 여러가지 이 부위의 원인에 의하여 정상 비호흡이 어려워지면 만성 비폐색 (chronic nasal obstruction)이 생기게 되고 따라서 환자는 입이 반쯤 벌리고 구호흡(mouth breathing)을 하게 되며 우둔한 인상을 주고, 상악치아의 발육이상을 초래할 수 있다. 여기에 필자는 이비인후과 영역에서 구호홉을 초래할 수 있는 질환들에 관하여 약술하고자 한다.

  • Ectopic mediastinal parathyroid adenomas are rare, but can be life-threatening. Resection is indicated in those cases accompanied by hypercalcemia, especially in young patients. Although most mediastinal parathyroid adenomas can be removed by a cervical approach, a transthoracic approach is needed when the adenoid tissues are located deep within the thoracic cavity. We describe the case of a 37-year-old female who underwent excision of an intrathoracic ectopic parathyroid adenoma after parathyroidectomy four months earlier.

  • Although fine needle aspiration cytology (FNAC) has become one of the primary tools for diagnosing salivary gland lesions, some of these methods continue to confuse pathologists. The most common problems occur so-called basaloid neoplasms. Basal cell adenomas are frequently misdiagnosed as pleomorphic adenomas, and in worse cases, as adenoid cystic carcinomas. The cytologic diagnostic accuracy of basaloid neoplasms could be increased by a better understanding of the histology and the nature of the tumor cells. These are displayed well in aspiration smears. A consideration of differential points on the basis of the epithelial-stromal relationship is offered in this paper.

  • 주로 작은 침샘에서 발생하는 샘낭암종의 치료 방침은 수술과 수술 후 보조적 방사선치료가 주로 행해져 왔다. 그러나 설근부에 발생한 샘낭암종에 대해서는 수술적 치료가 가져오는 삶의 질의 저하가 크기 때문에 수술적 치료를 적용하기 쉽지 않다. 또한 샘낭암종의 치료에 있어서 항암제의 역할이 거의 없는 상황에서 방사선치료가 중요한 역할을 할 수 있겠다. 이에 본 저자들은 설근부에 발생한 샘낭암종 세 증례의 방사선치료 결과를 보고 하며 샘낭암종의 치료에 대해서 문헌고찰을 통해 논의하고자 한다.

  • Epithelial-myoepithelial carcinoma(EMC) is a rare low grade malignant salivary gland neoplasm that most commonly occurs in the parotid gland but can also arise in minor salivary glands. It is a distinct neoplasm characterized by tubular and solid growth patterns and a dual cell population including an inner larger of cuboidal to columnar epithelial cells which are peripherally bounded by a layer of myoepithelial cells with distinctly clear cytoplasm. The clinical course is characterized by a high incidence of local recurrence and not infrequent distant metastasis. The differential diagnosis included acinic cell tumor, adenoid cystic carcinoma, mucoepidermoid carcinoma, sebaceous carcinoma and pleomorphic adenoma. We report a case of EMC of left parotid gland in a 55-year-old woman.
