Background: A diagnosis and treatment of chest wall tuberculosis (CWTB) is both difficult and controversial. The aim of this study was to collect information on the optimal treatment for CWTB. Methods: The clinical features, radiographic findings, and treatment outcomes of 26 patients, who underwent surgery and were diagnosed histopathologically, were retrospectively analyzed. Results: The most common presenting symptom was a palpable mass found in 24 patients (92.3%). In all patients, CT revealed a soft tissue mass that was accompanied by a central low density, with or without peripheral rim enhancement. The sensitivity and specificity of the bone scintigram for bone involvement were 87.5% and 100%, respectively. CWTB was diagnosed preoperatively by aspiration cytology and smear for acid-fast bacilli in five out of 11 patients. Twenty-three patients (88.5%) underwent a radical excision and three underwent incision/drainage or an incisional biopsy. The duration of antituberculous medication was 7.5${\pm}$3.98 months with a follow-up period of 28.2${\pm}$26.74 months. Among the 20 patients who completed their treatment, nine received chemotherapy for six months or less and 11 received chemotherapy for nine months or more. Two patients had a recurrence four and seven months after starting their medication. Conclusion: A 6 month regimen may be appropriate for CWTB patients who have undergone a complete excision.

Purpose: Supernumerary nipple or polythelia is one of the developmental anomalies occurring at the embryonic stage and this anomaly usually arises from the milk line. While this atypical feature is determined during early developmental stage, it may not come out obviously or become troublesome until puberty or lactation. Moreover, sometimes it is confused with a pigmented nevus. Methods: Case 1, a 18-year-old woman with intramammary supernumerary breast consisted of another nipple with middle sized areola on the right lower breast was admitted for a $2.8{\times}3.1\;cm$-sized mass on the right breast which was starting appeared 1 year earlier. The preliminary cytological examination of the material obtained by needle aspiration biopsy from the mass was revealed by fibroadenoma with no malignant change. The patient had the surgical excision of the mass and accessory breast. Case 2, a 16 year-old woman admitted for intra-areolar polythelia of the left breast, even she doesn't have any family history of polythelia. Since she wanted surgical correction of her atypical nipple for aesthetic and psychological reasons, we reconstructed the areola using transposition flaps in an S-plasty design. Results: Case 1, the excised supernumerary nipple showed following histological features. In the superficial layer, an acanthotic and hyperpigmented epithelium with elongated rete ridges was found. In the dermis, there were follicles with hairs surrounded by hypertrophic sebaceous glands. In the deepest portion, abundant secretory glomerules and excretory ducts of apocrine gland type were observed. Case 2, follow-up visits 3 months after the procedure showed a satisfactory result with good shape and projection of the nipple. Conclusion: We report two cases of aberrant mammary tissue who underwent surgical correction, including complete breast (with nipple, areola, and glandular tissue) and intra-areolar polythelia according to the Kajava's classification, and the results were satisfactory.

This is a report on four cases of the lobar emphysema due to proximal bronchial obstruction in the Department of Thoracic Surgery, Hanyang University Hospital, during the period of three and half years from 1972 to 1975. First case, a two years old male child was referred to our Department with the lobar emphysema of the lower lobe of the right lung with pneumonia. This emphysema was developed after aspiration of a piece of peanut. Bronchoscopy revealed that the bronchus of the right lower lobe was obstructed with the foreign body, however removal of the peanut through bronchoscope was not attempted because of corruption and softening of the peanut. The removal of the peanut by bronchotomy was performed after subsiding of acute phase of pulmonary infection. Postoperative course was uneventful and the emphysema was disappeared. Second case, a twenty months old female baby was referred to our Department with lobar emphysema of the lower lobe of the left lung. The emphysema was suddenly developed with coughing and dyspneic symptoms and the diagnosis was made roentgenologically. She gave a history of reccurrent infections of the respiratory tract after birth. Bronchoscopy showed an obstruction of the left main bronchus with the growing of fibrinous tissue on the bronchial mucosa. The protruded tissue in the left main bronchus taken out about O.8ml with biopsy forceps for histological examination. After this procedure, the emphysema of the left lung was disappeared. Histological finding was reported to be a chronic inflammatory granulation tissue. Third case, a two and half years old male child was referred to our Department with roentgenological lobar emphysema. Two weeks prior to admission he had an episode of sudden onset of coughing attack with dyspnea. Bronchoscopy revealed that the bronchus of the left lower lobe was obstructed with a mass which was strongly suspected of a neoplastic tissue. At operation, there was found a perforation of enlarged tuberculous lymph node in the bronchus of the left lower lobe and protrusion of granulation tissue into the bronchus. Ruptured orifice on themembranous wall of the left lower lobe bronchus was closed with interrupted suture after the" removal of a perforated tuberculous lymph node. Postoperative course was uneventful and antituberculous chemotherapy was given. Fourth case, a 47 years old man was admitted to our Department with the complaint of severe dyspnea of few months duration. Twenty years ago, he had a history of lung tuberculosis and was treated for many years. X-ray examination including tomography and bronchography revealed that the upper lobe of the right lung was destroyed with cavities, the lower lobe was completely shrunk, and the right middle lobe was strongly overdistended with narrowing bronchial trees. Differential bronchospirometry and lung scanning confirmed that the respiratory function of the affected lung was impaired almost totally. The value of the right lung was calculated on 6% of oxygen uptake, 1% of Minute volume, and 32% of vital capacity. The right pneumonectomy was performed under the careful consideration of anesthetic and surgical procedures. Postoperative course was uneventful and the respiratory function was improved nearly to the normal level.evel.

Purpose: Parotid neoplasia are relatively frequent, representing approximately 3% of all tumors in the head and neck regions. But incomplete resection and misdiagnosis of parotid gland is followed by multiple tumor invasion, tumor recurrence, and other iatrogenic tumor formation. In patients undergoing parotidectomy for confirmed or suspected malignancy, the traditional or modified rhytidectomy incision may prove suboptimal because it does not easily lend itself to a continuous neck dissection. Similarly, patients with tumors of the anterior accessory lobe or patients with large anterior tumors may also require the modified Blair incision for adequate surgical exposure. This report serves to revisit the topic of accessory and parotid gland neoplasms to emphasize proper management, particularly the surgical aspects, so that consequences of recurrence are avoided. Methods: This is a retrospective review of our experience with two cases of parotid tumors; one accessory parotid gland neoplasm and one parotid gland neoplasm. We report the case of parotid tumor and epidermal cyst in a 54-year old male patient and the case of case of recurrent parotid tumor with local invasion in 30-year old male patient. Results: All were removed through a modified Blair incision. Pathologic report notified that One was found pleomorphic adenoma and epidermal cyst, and the other one pleomorphic adenoma with subcutenous invasion. The patients recovered well without any complication such as infection, hematoma, facial nerve palsy, and necrosis of skin flap. Patients were discharge POD#7. Patients were followed up to for 1 year and they have no sign of recurrence. Conclusions: A high index of suspicion, prudent diagnostic skills(including fine-needle aspiration biopsy, CT, US), and meticulous surgical approach are the keys to a successful management of these lesions. We experienced two cases of parotid neoplasia, in the treatment of tumor reccurence & iatrogenic tumor arising from the parotid gland and are presented with the review of literatures.

Benign lung tumors have been considered as relatively rare disease, which comprise approximately 8 to 15% of all solitary pulmonary lesions that are detected radiographically. We clinically analized 30 cases of benign lung tumors underwent the operation from Jan. 1970 to Aug.1991 in the department of thoracic and cardiovascular surgery, Catholic University Medical College. We adopted the classification presented by the World Health Organization[WHO], modified from Liebow, and added benign mesothelioma. There were 11 males & 19 females ranging in age from 2 years to 68 years old % the mean age was 38 years old. Of all 30 benign lung tumors, hamartomas [14 cases, 49%] were the most common & followed by hemangiomas [9 cases, 30%], 3 cases of benign mesotheliomas % a case of teratoma, papilloma, arteriovenous malformation and inflammatory pseudotumor. 14 cases of tumors were asymptomatic & were incidentally detected by plane chest x-ray In other cases, chief complaints at admission were coughing, chest discomfort, dyspnea, hemoptysis, and fever. Diagnosis were made by pathological examination; exploratory thoracotomy in 23 patients[76.7%], bronchoscopy in 4 patients and percutaneous needle aspiration biopsy in 3 patients. Precisely, preoperative diagnosis for confirmation of benign lung tumor was made only in 7 cases[23.6%]. Tumors were located on Rt.side[24 cases], especially Rt. middle lobe, and Lt.side[6 cases]. Operation methods were as follows: 21 cases [70%] of lobectomy, 2 cases of segmentectomy, 2 cases of wedge resection, 1 case of pneumonectomy, 1 case of bronchotomy, 2 cases of wedge resection, 1 case of pneumonectomy, 1 case of bronchotomy removal of the endobronchial hamartoma which located at the rt. main stem bronchus and 3 cases of complete resection in benign mesotheliomas. There were no operative death. The post operative complications were developed in 3 cases; post pneumonectomy empyema, wound infection and atelectasis. In conclusion, benign lung tumors must be histologically diagnosed to confirm of benignity and to provide limited resection for preservation of the lung tissue, whenever possible.

19세기말과 20세기초에 각각 비르효와 파파니콜로에 의해 명료하게 된 세포 병리학과 탈락세포학의 개념에서 오늘날의 암진단의 일차적인 방법이 발전해 왔다. 파파니콜로의 탈락세포학의 개념에서 1960년대 초반에 세침흡인 세포검사가 개발되었다. 이 세침흡인 세포검사는 주된 진단방법이 되어져, 절개생검을 감소하게 하고 의료비용의 효과적인 이용에 공헌하였다. 1980년대에는 면역생화학적 기술들이 암 진단에 보충역활을 하게 되었다. 단 클론 항체를 이용하는 면역과산화효소법이 먼저 암의 본성을 밝히는 보조적인 방법으로 쓰여졌다. 특정 단클론 항체들이 이용가능하게 되어 세포산물이나 표면 표지자들을 인지하는 것을 훨씬 용이하게 하였다. 예를 들면 중간세사에 대한 항체들이 분화가 나쁜 종양의 조직기원을 결정하는데 가치가 있는 것이 증명되었다. 종양표지자들은 종양존재의 생화학적 표시자로 이용될 수도 있는데 이러한 종양표지자들은 혈장이나 다른 체액들에서 검출할 수 있다. 이 종양표지자들을 농출한 것을 진단적 검사에 이용하여 이미 진단된 암의 임상 경과를 추적하고 암 발생의 위험이 있는 집단에서 특정 종양을 발견해 내기 위한 선별검사로써 이용할 수 있다. 유세포 검사는 백혈병이나 림프종 세포들의 면역표현형을 알아내고, 종양세포들의 DNA함유량을 알아내며, 세포증식율을 알아내는 등의 몇가지의 세포의 특성을 분류해내는데 유용한 도구이다. 분자생물학적 방법들은, 암 환자를 진료하는데 있어 진단, 예후평가 및 치료 등의 분야에서 일보 전진하게 하였다. 핵산교잡법이 Southern blots, Nothern blot, Dot blot 및 in situ hybridization으로 이용된다. 분자생물학 및 그 기술이 암종 생물학을 이해하고 유전자 조작을 기초로한 치료법을 계획하는데 밝은 새로운 지평선을 열어줄 수 있을 것이다.

초음파영상은 갑상선 질병에서 결절성 갑상선 질병을 진단하는 검사로서 결절의 위치, 크기, 개수, 내부 에코 특성에 대한 정보를 제공하여 암의 가능성이 높은 고위험 결절을 선별하며, 세침흡인 검사 시 정확한 유도를 가능하게 한다. 갑상선 결절 중 악성으로 진단되는 경우는 5% 미만이지만 초음파에서 감별진단이 중요하다. 그러므로 본 연구에서는 병리학적으로 갑상선 유두암으로 진단된 증례를 실험 대상으로 하며, 영역을 묘사하는 알고리즘으로 그 질감을 정량화하는 방법으로 질감특징 분석(TFA)를 적용하여 컴퓨터자동진단의 검출 효율을 실험하였다. 초음파영상에서 관심영역을 설정하여 $50{\times}50$ 픽셀 크기, 히스토그램 평활화로 전처리하여 실험영상을 획득하였다. 전체영상 70증례에서 갑상선 유두암의 영상 35증례를 테스트 영상으로 하고, 고유영상 생성의 정상영상 35증례를 학습영상으로 실험하였다. 질감특징 분석 알고리즘을 적용한 실험결과 GLavg, SKEW, UN, ENT 4개 파라미터의 질병 검출 효율이 91~100%로 높게 나타났다. 이는 갑상선 결절 질병을 감별하는 컴퓨터자동진단의 응용을 나타내며, 갑상선 질병의 감별진단에 전처리 자동진단 가능성을 나타낸다. 향후 추가적인 관련 알고리즘의 연구가 계속 진행된다면 갑상선 질병의 컴퓨터자동진단의 실용화기반을 마련할 수 있을 것이고, 다양한 초음파영상의 질병에 대한 적용이 가능할 것으로 사료된다.
