For many years it has been reported that seemingly benign neck cysts may contain carcinoma. Cystic metastases have often mistaken for either branchial cleft cysts or benign mass. Authors experienced two cases which presents cystic cervical metastatic cancer One was a tonsillar carcinoma and the other was a tongue carcinoma. Patients with a cystic squamous carcinoma in the neck likely have a primary in upper aero-digestive system and It is known that the tonsil is most common site. Radiologic examination and fine needle aspiration biopsy of the cyst proved to be non-diagnostic. The development of cervical lymph node metastases before clinical signs of carcinoma of the tonsil is also well recognized. So, in old patients, thorough head If neck examination, panendoscopy and ipsilateral tonsillectomy is mandatory to identify a primary carcinoma prior to cyst excision.

Giant cell tumor(GCT) occurs very unusually in the rib(less than 1% of GCT). We present the cytologic features of GCT of the rib. It showed multiple cellular clusters composed of characteristic, benign looking osteoclast-like multinucleated giant cells and fibroblast-like mononuclear cells. The multinucleated giant cells contained numerous nuclei (average, 30 to 40 per cell, which were closely packed. The nuclei in giant cells were remarkably uniform and round to oval. The mononuclear, neoplastic stromal cells were elongated and spindle-shaped. There was no cytologically malignant portion in the tumor.

Fine needle aspiration (FNA) cytology of breast disease is recognized to be highly accurate and cost effective, especially when this is used in combination with clinical examination and imaging as part of a triple approach. A probabilistic/categorical approach is used for the classification of breast FNA specimens. Criteria are defined from the perspective of the likelihood of making a definitive diagnosis of cancer on excision. This approach is an accurate way of classifying breast FNA specimens, and this can be reliably applied regardless of the level of experience of the pathologist for interpreting the case. When a definitive diagnosis of malignancy is made, the next step is to determining the specific histologic types of the malignancy according to their cytological features. In order to make an accurate diagnosis of carcinoma and for correct typing a tumor, an adequate, correctly sampled aspirate without any other artifacts is required.

Spontaneous pneumothorax is the sudden collapse of a lung usually caused by air leaking from a sub-visceral pleural bleb. Response to closed thoracotomy, needle aspiration and simple observation is usually prompt and effective. But in some cases, these are unsuccessful and open thoracotomy is indicated. Author reviewed 37 cases of open thoracotomy in spontaneous pneumothorax experienced in the Dept. of Thoracic and Cardiovascular Surgery, Pusan National University Hospital, since Jan., 1980 to Dec., 1984. The results were as follows: 1. The causes of spontaneous pneumothorax: 73.0% was primary, 27.0% was secondary origin. 2. The most frequent age group of the patient: Between 11 and 30 years old. 3. All of te patient were male. 4. The side of open thoracotomy: 58.8% was right side, 8.8% was both side. 5. The most common indication of open thoracotomy; Persistent air leakage. 6. The most frequent sites of bleb or bullae: A-P segment in the L.U.L. and apical segment in the R.U.L.

Fifty-two cases of spontaneous pneumothorax encountered in Seoul National University Hospital during the period from 1961 to 1968 were reviewed. The incidence was highest in the adult between 21 and 40 years of age, showing 50%. Four cases of bilateral spontaneous pneumothorax [7.7%] were noted. Pulmonary tuberculosis was the most common cause, 50% of the cases. Non-tuberculous group was 26 cases [50%], of which 15 cases were idiopathic, 5 emphysematous bullae or blebs, 5 inflammatory lung disease, mostly pneumonia, and one pulmonary paragonimiasis. Among 52 cases, the lung expanded completely with absolute bed rest in 7 cases, 3 out of 9 with needle aspiration and bed rest, 34 out of 41 with closed thoracotomy and underwater seal Stedman suction, and 7 cases were treated with open thoracotomy with resection of the lesions without complication. Among these cases treated with closed thoracotomy it took about 3 days in non-tuberculous group to expand the collapsed lung and more than 2 weeks in tuberculous group.

We have observed 165 cases of spontaneous pneumothorax from Aug. 1978 to May. 1985 at the department of Thoracic and Cardiovascular Surgery, School of Medicine, Keimyung University. The ratio of male to female cases were 8.2:1 in male predominance, and the incidence was highest in the adolescence between 21 to 30 year of age. There were 85 patients of primary spontaneous pneumothorax and 80 patients of secondary spontaneous pneumothorax. The etiologic factors of secondary spontaneous pneumothorax were tuberculous origin in 50 cases, chronic bronchitis with emphysematous bullae or blebs in 17 cases, asthma in 10 cases and lung cancer in 3 cases. Closed thoracotomy was performed for reexpansion of collapsed lung in 153 cases, bed rest in 3 cases, needle aspiration in 5 cases and open thoracotomy in 14 cases. Closed thoracotomy was the main therapeutic approach of choice in the great majority of spontaneous pneumothorax with recurrence rate of 21.6%. However, open thoracotomy was undertaken in patients with continuous air leakage, recurrent episodes, bilateral pneumothorax and large visible apical blebs or bullae.

Primary pulmonary meningioma is an extremely rare disease. It is mostly benign and asymptomatic. This tumor shows the same cytohigstologic appearance as brain or spinal cord meninioma. It can be diagnosed as a primary pulmonary meningioma only if there is no evidence of metastasis from the brain or spinal cord meningioma. We experienced a case of primary pulmonary meningioma in a 60-year-old woman who had asymptomatic 2 cm-sized solitary pulmonary tumor in the right lower lobe. It is rather peripherally located. Fine needle aspiration cytology has suggested the possibility of either well-differentiated epithelial malignancy such as papillary adenocarcinoma or mucoepidermoid carcinoma or metastatic carcinoma such as from ductal carcinoma of the breast. Right lower lobectomy was performed. The tumor was bilobated and soild with yellowish color. pathologically it proved to be a primary pulmonary and solid with yellowish color. Pathologically it proved to be a primary pulmonary meningioma because there was no evidance of brain or spinal cord tumor. To the best of our knowledge this is the first case reported in Korea. We report this case with review of the literature.

폐의 결핵종은 드물지 않게 관찰되는 소견이다. 그러나, 폐의 이소성 간은 매우 드물다. 결핵종으로 보여지는 폐결핵은 방사선적 소견으로 진단이 가능하지만 확진은 항산균을 확인하거나 조직학적 소견으로 한다. 초음파하 세침 흡인 조직 검사로 이소성간으로 잘못 진단된 좌하엽의 결핵종 증례를 보고한다. 간의 정상적 변이에 대한 이해가 불필요한 침습적 시술을 예방할 수 있으리라 생각된다.

A five-year-old female Yorkshire Terrier dog presented with a perianal mass. Fine needle aspiration revealed that the mass comprised two different types of cells: hepatoid epithelial cells and melanin-containing melanocytes. Histopathological examination confirmed perianal gland adenoma with malignant melanoma. Evidence of metastasis was found on thoracic radiography with soft-tissue densities observed within the pulmonary parenchyma. The dog survived for three months after diagnosis of malignant melanoma. This report describes the clinical findings, diagnostics used, cytological and histopathological findings, and the potential prognosis for a dog diagnosed with malignant anal sac melanoma.
