During the period of 10 years from July, 1976 to July, 1986, 154 cases of primary carcinoma of the lung - by the cell type, stage, operability, and survival rate in the resectable cases - are analyzed at the Dept. of Thoracic Surgery, Paik Hospital in Seoul. The results are as follows: 1] Histopathological types are squamous cell carcinoma 49% [76 cases], adenocarcinoma 25% [39 cases], undifferentiated large cell carcinoma 9% [14 cases], undifferentiated small cell carcinoma 6% [9 cases], bronchioloalveolar carcinoma 4% [6 cases] and adenosquamous carcinoma 3% [4 cases]. 2] Peak incidence is observed in the 4th decade of life [33%], then 5th [29%] and 3rd [21%] respectively. Male to female ratio is 4 to 1. 3] Evidence of inoperability is observed in 64% [99 cases] by clinical staging workup. Thirty six percent [55 cases] were operated. Of these, post-surgical stage I was 5% [3 cases], stage II, 64% [35 cases] and stage III, 31% [17 cases]. Among total 17 cases of stage III, 14 cases were unresectable with evidence of T2N2M0, while 3 cases were resectable. Resectability is 27%, [41 cases] from the total number of 154 cases. And the resectability for the ex 55 cases is 75% [41 cases]. 4] By cell type, highest resectabitity is the squamous cell carcinoma, 49% [20 cases]. Adenocarcinoma is 32% [13 cases] and bronchioloalveolar, 12% [5 cases]. 5] Survival rate is evaluated for 38 cases of 41 resectable stage I, II and III. Overall 5 year survival rate is 24%, 3 year 32% and 10 year 8%. Survival rate in stage II for 5 year is 25%. In squamous cell type for, 5 year is 42%. Authors believe when surgeons continuous effort of early detection is met with patients early visit, 5 year survival rate for the stage I K II resectable patients will improve more effectively. As well, When the efforts are added to combined modality with radiotherapy and chemotherapy for the stage III selected cases of non-small cell carcinoma patients, the enhancement in survival rate is expected.

We report 4 cases of malignant thymoma which were composed of 2 cases of invasive thymoma and 2 cases of thymic carcinoma. The cytologic findings of invasive thymoma were similar to those of benign thymoma. The distinctive cytologic features of thymic carcinoma were necrotic background, irregular clusters and individually scattered arrangement of anaplastic epithelial cells, and some scattered mature small lymphocytes. These findings may be found in the Hodgkin's lymphoma, seminoma, and metastatic squamous ceil carcinoma, undifferentiated carcinoma, and large ceil carcinoma of the lung. But, the feature of irregular clustering of anaplastic epithelial cell haying scanty cytoplasm was different from Hodgkin's lymphoma and seminoma. Clinical and radiologic findings as well as cytologic finding were helpful in differential diagnosis of thymic carcinoma from metastatic carcinoma.

We observed 88 csses of primary lung cancer clinically and statistically, which had been experienced at the dept. of thoracic surgery, St. Mary's Hospital, Catholic Medical College, during the period of 7 years from January, 1964 to December, 1970. The results obtained were as follows: 1) Peak incidence of age was from 5th decade to 7th decade (86.4%), the youngest being 25 and the oldest 76. The ratio of male to female was 4.9: 1. 2) Squamous cell carcinomas showed high resectability (68.7%) and short clinical duration (188 days). Adenocarcinoma and undifferentiated carcinoma showed low resectability (33.3%, 36.4%) in spite of the more shorter clinical duration(120 days, 112 days, respectively) than squamaus cell carcinoma. 3) Positivity (above class III) in brochocopic cytology was 70.3%, and 44.8% in fresh sputum cytology. 4) Other combined pulmonary diseases (emphysema. chronic bronchitis) were noted in about one half of bronchographied 66 cases and which were considered as factors to contribute ventilatory function of lung. 5) Among 88 cases, twelve cases refused operation and 34 cases(44.7%) were operated. Seventeen cases(22.3%) out of the 34 thoracotomies were resected, 7 with lobectomy and 10 with pneumonectomy and remaining 17 cases were unresectable. 6) Histopathological findiugs of resected 17 cases were squamous cell carcinomas (11 cases), adenocarcinoll1a(1 case), undifferentiated carcinumas (4 cases) and undetermined carcinoma(l case). 7) There's no opelative mortality. Among resected 17 cases, [; cases are still alive(4 years, 3 years & 2 mo, 2 yearo, 13 mo., respectively), 7 case were expired (3 of these from remote metastasis), and remaining 5 cases were unable to follow up.

Sinonasal Undifferentiated Carcinoma (SNUC) is a very rare, highly aggressive malignant tumor of the nasal cavity and paranasal sinuses. SNUC tends to present with advanced-stage disease, often with intracranial invasion. It requires an aggressive multimodality therapy that includes surgical resection. A cure rate of less than 20% is generally reported in the literature, with most patients dying within 1 year of onset of the disease. Three patients diagnosed as SNUC were treated at the Yeungnam University Medical Center between the years 2000 and 2003 were analyzed retrospectively. All patients presented with the disease very advanced. The three cases were given chemotherapy or chemotherapy with radiotherapy. Two patients died of the disease, surviving only 6 and 11 months following treatment, respectively. We did a follow-up on just the one remaining case with incomplete controlled disease for 27 months. The overall prognosis of SNUC is very poor. We consider that more intensive multimodality therapies are recommended for all patients with SNUC.

A 37 year-old male presented with sudden right proptosis and bilateral nasal obstruction. A huge tumor was noted in bilateral nasal cavities, ethmoid sinuses and central frontal sinus on magnetic resonance imaging. Right posterior frontal sinus wall and bilateral medial orbital wall was destructed by the tumor. Complete resection of the tumor was performed via minimal invasive craniofacial resection. Histopaghologic examination revealed sinonasal undifferentiated carcinoma (SNUC). Cerebrospinal fluid leakage was developed after 2 days of the surgery. On the 5th day, anterior skull base was reconstructed with forearm free flap (FFF). The patient got 6000cGy of radiotherapy and survived in 27 months of follow up.

An eight-year-old, intact female, Shih-Tzu, weighing 4.5 kg presented with complaints of anorexia, pale mucous membrane, and vomiting for the past 5 days. On physical examination, nausea, abdominal pain, and melena were noted. On hematologic examination, severe anemia and thrombocytosis were identified. On radiographs examination, soft tissue opacity with small faint mineral opacity mass in the mid-abdomen and two mineral opacity regions in the cranial aspect of mass were identified. Ultrasonographic findings showed thickening of descending duodenal wall with loss of layering and mineralization within the duodenal wall and mesentery adjacent to the duodenal lesion. Computerized tomography showed circumferential wall thickening of descending duodenum with mineralization. Mineralization of the mesentery and mesenteric lymph nodes was identified. Based on the diagnostic imaging, the tentative diagnosis was descending duodenal tumor with dystrophic mineralization. Endoscopy revealed mucosal hemorrhage and erythema within the descending duodenum and stomach. Surgery was performed, and mineralization in the pancreatic tail to duodenum and mesentery was found. Resection of the duodenum, regional lymph node, and mineralized pancreatic region and the duodenal anastomosis were performed. The histologic examination revealed a high-grade undifferentiated duodenal carcinoma with metastases to the regional lymph node and mesentery. The patient was managed with supportive therapy for 8 days and discharged. The patient was followed up for 5 months and there were no complications.

Lymphoepithelioma-like carcinoma exhibits immunohistochemically similar features to lymphoepithelioma and commonly occurs in the skin, salivary gland, breast, lung, gastrointestinal tract, liver, urinary tract, prostate, vulva and vagina. Lymphoepithelioma-like carcinoma from the thyroid gland is extremely rare. We recently experienced a case of lymphoepithelioma-like carcinoma of thyroid gland in a 28-year-old female, who presented a thyroid nodule that was suspicious of papillary carcinoma. We report this unusual case of lymphoepithelioma-like carcinoma of thyroid gland with a brief review of literature.

In the presence of clinical evidence and chest roentgenogram suggestive of bronchogenic carcinoma, reliance is almost wholly placed on Papanicolaou staining of the sputum, bronchoscopy, and biopsy of peripheral lesion, together referred to as the "diagnostic triad". However, bronchography remains relatively non-utilized. Our experience with 56 bronchograms in which the modality of bronchial obstruction, distance to obstruction and reduction rate of caliber in leading bronchus were used in an attempt to explain underlying chest pathology and operability of bronchogenic carcinoma, indicated as follows: 1. The bronchographic findings in bronchogenic cancer consist of malignant bronchial obstruction in which the modality of obstruction is classified as abrupt type, conical type and compressed type in incidence of 50.0%, 23.2% and 26.8%, respectively. 2. Abrupt type of bronchial obstruction is more common in hilar type and particularly in squamous cell and undifferentiated cell type of bronchogenic cancer. In this type of obstruction the inoperability revealed in 57.8% and resectability in 17.8%. 3. Conical type of obstruction was a sign of most malignancy, in which 61.5% was undifferentiated cell type and 38.4% was squamous cell type. All this type of obstruction was inoperable even feasibility was presumed in simple roentgenograms. 4. Compressed type of obstruction was more common in peripheral type of bronchogenic cancer and showed 50.0% of resectability. 5. The distance from carina to bronchial obstuction revealed average 3.8cm in undifferentiated type, 5.76cm in squamous cell type and 7.60am in adeno cell type of carcinoma. 6. The reduction rate of caliber in leading bronchus to obstruction (mm per unit cm lenghth of leading bronchus) revealed average 2.15mm/cm in undifferentiated type 1.90mm/cm in squamous cell type and 1.13mm/cm in adeno cell type of carcnoma. 7. The reduction rate of caliber in leading bronchus showed 2.14mm/cm in inoperable cases and 1.42mm/cm in resectable cases. 8. The modality of bronchial obstruction and estimation of the reduction rate of caliber seemed to be a most reliable key-point to decide feasibility of resection.
