Adenoid cystic carcinoma is a relatively rare tumor that usually arises in the parotid and submandibular salivary glands. The initial management is surgical, and this is often combined with post-operative radiotherapy, but local relapse is common and distant metastasis is not infrequent. We experienced the case of a 59 years old male who had been previously operated on for a primary submandibular salivary cyst, and he then had a distant pulmonary metastasis 9 years later. We operated on him with performing a wedge resection on the left lower lobe for the metastatic lesion, and he hasn't had any evidence of tumor recurrence for 84 months after the second operation.

The basal cell adenoma of the parotid gland is rare benign disease, first described and adequately documented as a distinctive tumor from benigh mixed tumors(pleomorphic adenoma) by Kleinsasser and Klein in 1967. This tumors is an isomorphic epithelial tumor of salivery gland, characteristic of absence of myoepithelial cells which are present in pleomorphic adenoma and other salivery gland tumors. Clinicopathologically the tumors is very difficult to differentiate with pleomorphic adenoma or adenoid cystic carcinoma. The prognosis is excellent by complete extirpation of the tumor. The present report presents two cases of basal cell adenoma of the parotid gland seen in 63 year old man and 71 year old man in one-year period at Department of Surgery, Yonsei University, College of Medicine.

Background/Objective: The survival and recurrence pattern of the patients with primary cancer of the external auditory canal was evaluated. Materials & Methods: Seventeen patients with primary cancer of the external auditory canal from 2002 to 2013 was analyzed retrospectively. Overall survival, recurrence free survival, local recurrence free survival and distant metastasis free survival was calculated by Kaplan-Meyer's method. Results: Five year overall survival rate, 5 year recurrence free survival rate, 5 year local recurrence free survival rate and 5 year distant metastasis free survival rate were 49.3% 54.9%, 64.7% and 69.6% respectively. The recurrence pattern is different to the pathologic type, squamous cell carcinoma or adenoid cystic carcinoma. The patients with squamous cell carcinoma showed local recurrence and the patients with adenoid cystic carcinoma showed distant metastasis mainly. Conclusion: Primary cancer of external auditory canal showed different clinical course depend on the pathologic diagnosis.

Fine needle aspiration biopsy cytology is a widely recognized and useful technique which can provide diagnosis in lesions of the head and neck, enabling appropriate management plans for individual patient to be made. Fifty one fine needle aspirates from salivary gland masses were examined. Four aspirates (8%) were inadequate for examination. Of the remaning 47 samples, 42 cases (82%) were benign lesions which consist of 30 pleomorphic adenoma(58%), 7 inflammatory lesion (14%), 4 Warthin's tumor(8%) and 1 benign lesion(2%). Two cases(4%) were atypical lesions. Three cases(6%) were malignant lesions consisting of 2 adenoid cystic carcinomas(4%) and 1 mucoepidermoid carcinoma (2%). The cytologic diagnoses were compared with the subsequent histologic diagnosis of surgical resected specimen in 24 cases. 19 cases of 21 aspirates from benign tumors were correctly diagnosed by fine needle aspiration cytology, with a specificity of 90%. All 3 aspirates from the 3 patients with malignant tumor were correctly diagnosed by fine needle aspiration cytology, with a sensitivity at 100%. Overall acurracy was 88%. Diagnostic error was encountered in adenoid cystic carcinoma, mucoepidermoid carcinoma and Warthin's tumor Correct histologic diagnosis was made in 86% of benign tumors(84% for pleomorphic adenoma and 100% for Warthin's tumor) and in 100% of malignant tumors.

Primary neoplasms of the trachea are rare, but are a very serious critical life-threatening disease. Nearly all the lesions of the trachea are presented as obstructive lesions. Bronchoscopic examination including chest C-T, tomogram and air tracheogram are essential for the further definition of these lesions. The need for removal of tracheal tumors whether complete or incomplete, is clear enough regardless of the histology of the tumor. We have experienced 9 cases from Jan. 1965 to June, 1985. One patient with tracheal hamartoma was cured with complete resection through rigid bronchoscopy and another patient with fibrous histiocytoma was treated with re-excision and laser evaporation through superior mediastinotomy due to recurrence, 1 year later. The remaining patients were treated with mass excision or segmental resection and end-to-end anastomosis through collar incision and superior mediastinal sternotomy. The remaining two patients were operated with and segmental resection and end-to-end anastomosis of trachea using partial cardiopulmonary bypass. The histologic diagnosis were adenoid cystic Ca[5], fibrous histiocytoma[1], mucoepidermoid Ca[1]. hamartoma[1], anaplastic Ca.[1]. Three patients were treated post-operatively with radiation; with adenoid cystic Ca.[2] and anaplastic Ca.[1]. Their post-operative courses were uneventful during the follow-up from 2 months to 7 years.

Background : Primary adenoid cystic carcinoma arising in the bronchus is an uncommon disease that is histologically and ultrastructurally identical to the salivary gland tumor of the same name and regarded as a slow growing low-grade malignancy. We examined its clinical characteristics. Method : We collected 13 Korean cases of primary adenoid cystic carcinoma arising in the bronchus including 5 cases of our own and 8 cases from the literature. Result : The patients ages ranged from 20 to 74. Men numbered 9 and women 4. The presenting symptoms were cough, dyspnea, and hemoptysis. The fiberoptic bronchoscopic findings were primarily hypervascular polypoid mass with a smooth surface that obstructed airway totally or near totally. There were three inoperable cases including two cases with distant metastasis to bone or cervical lymph node and one case with mediastinal invasion. The remaining 10 patients underwent surgical resection. Among them, two patients received postoperative radiotherapy. The median survival was 21 months in the 8 surgical and evaluable cases. One patient lived 13 years without recurrence. The prognosis was relatively favorable in operable cases. Conclusion : It was not common for primary adenoid cystic carcinoma arising in the bronchus to have distant metastasis or invasion to the mediastinum on presentation. The prognosis was relatively favorable in operable cases. It would be important to perform flexible bronchoscopy for early diagnosis and to do surgical treatment if possible.

Background and Objectives： Adenoid cystic carcinoma (ACC) is an aggressive, often indolent tumor, with a high incidence of distant metastasis (DM). Relatively little has been written about the factor that influence distant spread and subsequent survival because it is uncommon and has protracted clinical course. We attempted to reemphasize the biologic behavior of ACC by investigating the relationship between the clinical features and prognosis. Materials and Methods : We have retrospectively studied 24 determinate patiens who received definitive treatment in our hospital between 1984 and 1995 for ACC in all salivary sites. Inclusion criteria were no prior treatment elsewhere other than excisional biopsy and eligibility for follow-up of at least 5 years. Variables assessed for their impact on distant metastasis included age, gender, size, node status, stage, histologic pattern, locoregional treatment failure. Results : Treatment failure occurred in a total of 16 of 24 determinate Patients (64%), 12 of whom had DM (50%). This was usually associated with locoregional recurrence (8 patients), but DM was the only indication of failure in 4 whose primary tumor was controlled. Of the 12 patients with known DM, the lung was recored as the only involved site in 7 Patients, lung was involved in addition to other sites in 1, bone and liver metastasis occurred in 2 respectively. Disease-free intervals varied from 3 month to 14 years (median 3 years). The only significant factors influencing survival were the size of the primary tumor, locoregional recurrence. Conclusion : The high incidence of DM with locoregional failure confirms the importance of aggressive initial surgery. combined with irradiation, for high-stage tumors or involved surgical margins. Large tumor size and locoregional recurrence, rather than microscopic appearance, were predictive of DM.

선낭포성 암은 대부분 타액선에 발생하는 질환으로 원발성으로 기관에 발생하는 경우는 매우 드물다. 이는 증상이 없이 서서히 진행할 수 있어 진단이 어렵고 늦어질 수 있으며, 기질적 질환을 발견하지 못하는 경우 기관지 천식으로 진단하에 치료를 하는 경우도 있다. 서서히 진행하기 때문에 치료 후의 판정에도 어려운 점이 있다. 저자들은 2년전 기관지 천식 진단 하에 호흡곤란이 있어 기관절개술 시행 후 기관탈관 곤란증으로 이비인후과에 입원한 례에서 기관에 발생한 선낭포성 암을 후두적출술로 치험하였기에 보고하는 바이다.

The authors reviewed 114 cases of malignant major and minor salivary gland tumors at Presbyterian Medical Center seen from February, 1963 to December, 1983. The results were obtained as follows; 1) Overall male and female sex ratio was 2:1. The peak age of patients with major and minor salivary gland tumor were both 5 th decade. 2) The ratio of benign and malignant tumor was 83:114. The incidence of malignancy in each group was 52% in parotid (50 patients), 75% in minor salivary gland (45 patients), 49% in submaxillary gland(18 patients) and 25% in sublingual gland (1 patient). 3) The incidence according to the anatomic primary site for minor salivary cancers was 10 cases in the nasal cavity, each 8 in the palate and the maxillary antrum, 7 in the tongue, 5 in the gum, 3 in the larynx and 2 in the buccal mucosa. 4) Adenoid cystic carcinoma was the most common cancer of minor salivary gland and malignant mixed tumor was the most common in major salivary glands, each comprising 34 cases (76%) of minor and 19 cases (28%) of major salivary gland tumors. 5) The incidence of cervical lymph node metastasis was 50% in the submaxillary gland cancers, 44% in the parotid gland cancers and 21% in malignant tumors of minor salivary glands. The highest incidence of lymph node metastasis according to histopathological classification was formed in high grade of mucoepidermoid (67%). 6) Nerve invasion was common in mucoepidermoid carcinoma. According to anatomic site, nerve invasion occurred most often in adenoid cystic carcinoma of the submaxillary gland (44%). 7) The lung was the commonest site for distant metastasis comprising 12 cases among 26 cases in which distant spread occurred. 8) The recurrence rate was 50% for major salivary gland cancer and 52% in cancer of the minor salivary gland. In accordance with pathological classification, adenocarcinoma most frequently recurred after excision. This being seen in 88% of patients undergoing definitive therapy. 9) The determinate 5 year survival rate was 78% in major salivary gland tumors, but 69% in minor salivary gland tumors.

Adenoid cystic carcinoma (ACC) commonly originates in the major salivary glands and respiratory tract, but it is extremely rare to find ACC in the esophagus. ACC of the esophagus is clinopathologically different from the salivary gland variant. It shows more aggressive malignant behavior and a very poor prognosis. We report here on the surgical and clinopathologic findings of ACC of the esophagus in a 65-year-old man, and we also include a review of the relevant medical literature.
