A total of 359 cases of malignant tumors of the larynx (including 87 resected cases) obtained from the pathology file of the Department of Pathology, College of Medicine, Seoul National University during a period of 10 years from 1976 to 1985 were studied by histopathologic and gross investigation with analysis of clinical records, with following results. 1) Out of 359 cases, 356 cases were primary and 3 cases were metastatic. The primary malignant tumors consisted of 348 cases (97.8%) of squamous cell carcinoma, each 2 cases of verrucous carcinoma, malignant lymphoma and undifferentiated carcinoma, a case of adenoid cystic carcinoma and a case of unclassified sarcoma. The metastatic malignant tumors were each one case of renal cell carcinoma, malignant schwanoma and esophageal squamous cell carcinoma. 2) In primary squamous cell carcinoma, the ratio of male to female was 7.8:1 and mean age was 58.2 years (35-87 years). The location was in order of the supraglottic (54.1%), the glottic (25.0%), the transglottic (18.0%), and the subglottic (2.9%). The degree of histologic differentiation was in order of well (72.7%), moderate (23.6%) and poor (3.7%). The tumor stage was stage I in 7.8% of cases, stage II 19.7%, stage III 38.5%, and stage IV 34.0%, and the supraglottic tumors were relatively higher grade than the glottic tumors. 3) The chief complaints of the primary squamous cell carcinoma were mostly hoarseness (70.9% in total case, 49.2% in the supraglottic, 90.9% in the transglottic, and 100% in the glottic and the subglottic), and were variable in the supraglottic cases in order of sore throat, neck mass, throat pain, dyspnea, swallowing difficulty, and foreign body sensation. The duration from the time of first symptom to vistiation was average 7.34 months and was less than 3 months in 45.6% of cases, and showed two peaks, major in 1-2 months and minor in 10-12 months. 4) In the 87 resected cases of primary squamous cell carcinoma, the gross pattern was the ulcerofungating type in 49.4% of cases, the ulceroinfiltrative in 47.1% and flat in 3.5%. The size of tumor was up to 1.5 cm in 30% of cases and more than 1.6 cm in 70%. The extent of invasion was to the submucosa in 40.7% of resected cases, to the laryngeal skeletal muscle(s) 16.3%, to the laryngeal cartilage(s) 33.7%, to the perilaryngeal soft tissue 9.3%. In the 65 cases of lymph node dissection out of these 87 cases, 25 cases (38.5%) showed metastatic lesion(s). With relation to tumor location, lymph node metastases were frequent in the supraglottic, the transglottic and the subglottic region (50-60%) and less common in the glottic region (13.8%). With relation to gross pattern, the metastases were most frequent in ulceroinfiltrative type and none in flat type. And the metastasis rate was increased according to the increase of the tumor size and to the decrease of the tumor differentiation. 5) Smoking history in 140 recorded cases revealed only 8 nonsmokers and average 35.39 pack-years of cigarettes in smoker group with peak in 20-40 pack-yeas (57.2%). 6) Distant metastases were found in 8 cases. The organs were the lung in 5 cases, brain 4 cases, liver 1 case (Three cases were positive in two foci, the lung and the brain). The coexistant primary malignant tumors were found in 8 cases which were 5 bronchogenic squamous cell carcinomas, 2 gastric adenocarcinoma, 1 pancreatic head adenocarcinoma and 1 thyroid papillary carcinoma (Triple primary cancers in one case, of the larynx, the lung and the stomach). 7) Follow-up of 6-53 months (mean 25.8 months) in 115 cases resulted in NED in 62 cases (53.9%) and expired or less resulted in NED in 62 cases (53.9%) and expired or loss of follow-up after recurrence or distant metastasis in 53 cases (46.1%). The recurrence was detected in 2-34 months (average 12.0 months) after treatment.

Twenty cases of the rheumatoid arthritis was carried out the histopathological observation from the affected synovial membrane at the knee joint by the Cops biopsy needle, at the Department of Orthopedic Surgery, Chosun University Hospital. The authors researched the difference to compare with the histological finding and its clinical features. The following results were obtained. 1. The average age was 36.9 years old and the sex ratio between the male and female was 1:2.7. 2. The erythrocyte sedimentation rate and protein amont in the synovial fluid was elevated than the normal value. 3. The most common clinical sign was the morning stiffness with multiple joint pain and moderate swelling, tenderess in the involved joint. 4. The test of rheumatoid factors revealed positive about 70% in the serum and 100% in the joint fluid. 5. The characteristic histological finding on the light microscopical examination was the hyperplasia of surface lining cells, deposition of the fibrin with the fibrinoid necrosis, and vascular hypertrophic changes of the blood vessel in all of those cases. 6. The histological finding had no difference to compare with the clinical course.

PURPOSE: The purpose of this study was to compare mammography and breast sonography in detection of breast cancer and to suggest reasonable guideline of breast imaging in breast cancer patients under 30 years of age in whom breast cancer shows different clinicopathologic characteristics compared with breast cancer in older women. MATERIALS AND METHODS: A. uthors reviewed medical records of 27 patients under 30 years of age with pathologically-proven breast cancer. Age, family history, physical examination findings, indications for breast s0nography were reviewed. Cases in whom breast cancer lesion is detectable and cases in whom not detectable using mammography or breast sonography were reviewed. And then, authors evaluated the usefulness of each method and reasons for nonvisualization of lesion on mammography. RESULTS: Among 27 patients, 25 patients had palpable breast mass as indication of mammography and breast sonography. Cancer lesions were detectable in 16 of 25 patients (64%) on mammography and 24 of 25 patients (96%) on breast ultrasonography. Reasons for nonvisualization of cancer lesions on mammography were dense breast with nodular parenchyma pattern and minimal breast change of ductal carcinoma in situ. CONCLUSION: In breast cancer patients under 30 years of age who have palpable breast mass as a initiaJ, and main clinical problem, breast ultrasonography is superior to mammography in detecting and diagnosing breast cancer. We suggest that guidelines can avoid unnecessary mammography in these patients.

BACKGROUND: Long-term phototherapy can induce the changes of photoaging and it is reported that there is an increased chance of cutaneous squamous cell carcinomas in patients exposed to large amounts of UV radiation. OBJECTIVE: The main objective was to investigate the degree of photoaging and the presence of p53 mutations in normal skin in patients undergoing long-term phototherapy. METHOD: We performed hematoxylin-eosin and special stains, p53 and p21 immunohistochemical stains and polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) on the normal skin of patients subject to long-term UV therapy. RESULT: 1. The typical features of photoaging were not observed in patients undergoing long-term UV therapy. 2. In p53 immunohistochemical staining performed at 1 week after cessation of long-term PUVA treatment, the patient group with a culmulated UV dosage of more than 1,000J/cm2 demonstrated an increased number of p53 positive epidermal cells compared to exposed as well as unexposed normal skins. 3. The patterns of p21 immunohistochemical staining performed at 1 week after cessation of long-term PUVA and UVB treatments were similar to that of p53 immunohistochemical staining performed at 1 week after cessation of phototherapy. 4. In p53 immunohistochemical staining performed at 4 months after cessation of UV treatment, the number of p53 positive epidermal cells decreased significantly compared to that of p53 positive epidermal cells found at 1 week after cessation of UV treatment. 5. The mutation of p53 genes was not found in PCR-SSCP analysis of biopsied skins done at 1 week after cessation of long-term PUVA and UVB treatment. CONCLUSION: Long-term phototherapy did not induce the typical changes of photoaging and p53 overexpression in the epidermis of UV treated skin was a reactive process. Therefore, UV therapy can be a relatively safe treatment modality, although a closer observation for cutaneous malignancy is warrented in the patients whose cumulated UV dosage is much higher than 1,000J/cm2.

CT scans of 23 patients with gallbladder carcinoma were retropectively reviewed to determine the incidence of lymphatic spread and to access the pattern of regional lymph node metastases. The lymphatic spread were noted in 74%(17/23). The involved patterns of regional lymph node metastases were nodes of porta hepatis 65%, portocaval nodes 41%, superior pancreaticoduodenal nodes 47%, posterior pancreaticoduodenal nodes 59%, nodes around the celiac trunk 35%, nodes around the superior mesenteric artery 29% and paraaortic nodes 35%. The findings suggested that the pattern of regional lumph node metastases in gallbladder carcinoma occurred along the normal lymphatic pathway of the gallbladder.

PURPOSE: The objective of augmentation mammoplasty includes reconstruction and cosmesis after breast surgery Increasing frequency of the procedure has been related with increased complications. Authors evaluated the value of breast MRI in the diagnosis of complications after augmentation mammoplasty. MATERIALS AND METHODS: Authors studied 42 breasts of 24 patients, who had undertaken augmentation mammoplasty. We evaluated findings of mammography, ultrasonography, and breast MRI in all patients. We used variable MRI sequences for better evaluation of implant status. The results were compared with the findings in surgical field. RESULTS: In all imaging studies, nodule or mass was indentifiable in the cases of interstitial paraffine injection(8 breasts), interstitial silicon injection(7 breasts), and herb medication(2 breasts). However, the differentitation between malignant and benign nodule was only possible at dynamic breast MRI. Mammogram was not helpful in the evaluation of extracapsular rupture in the cases of silastic bag insertion. In sonogram, identification of echogenic material was possible, although, false negative and false positive rate were high. MRI was able to visualize contour of entire implant and it was able to easily recognize low signal internal structure. CONCLUSION: MRI was the most accurate diagnostic tool in the evaluation of the character of the palpable mass after augmentation mammoplasty and early detection of breast implant rupture.
