Pulmonary lymphangiomyomatosis is a rare disease of haphazard overproliferation of smooth muscle from perilymphatics, peribronchial and perivascular regions of the lung that leads to chylous effusion, hemoptysis, spontaneous pneumothorax and pulmonary insufficiency. The disease only affects women of child-bearing age. There is presently no successful therapy and most of the patients die within 10 years of diagnosis. We experienced a case of pulmonary lymphangiomyomatosis in a 30-year-old woman who had suffered from three episodes of spontaneous pneumothorax for 4 years. Open lung biopsy was performed. Microscopically, abnormal excess proliferation of smooth muscle tissue was identified in the wall of perivascular lymphatic channels as well as around small bronchi, and more distal air spaces. Varying sized cytic spaces Iined by cuboidal cells were also present. Tamoxifen, given if February 1991, did not influence the course of her disease. She died of respiratory failure at age of 31 in April 1991.

Primary tumors of the adrenal cortex are comparatively rare. In the medical literature they are most frequently reported as single case. Because of their infrequent occurence some features of their clinical behavior and pathologic anatomy are not widely known. For this reason the recording of the 7 cases from the Department of Pathology, School of Medicine, Chungnam National University is thought to be worth while. Of the seven tumors, five were associated with primary aldosteronism, one Cushing's syndrome, and the remaing one virilizing syndrome. All were benign. Females were affected more frequently than males. Adrenocortical adenomas tend to be small, weighing less than 42 gm. The tumors associated with primary aldosteronism were composed of zona fasciculata-like cells and "hybrid" cells. The tumor with Cushing's syndrome consisted of zona reticularis-like cells. The tumor with virilizing syndrome consisted of zone reticularis-like cells.

The uterine cervical cancer is the rnost common tumor of malignant gynecologic tumors and complete remission of the cancer has been possible through early diagnosis and treatment. To evaluate the efficacy of tumor markers SCCA and CEA in patients with uterine cervical cancer as markers for monitoring, we analyzed serum SCCA and CEA crncentrations of 43 patients wit.h uterine cervical caner as a study group and 73 patients with benign pelvic disease as a contrnl group, were admitted to depar tment of Obstetncs & Gynecology, College of Medicine, Kyung Hee University from May 1991 to January 1993. The results were as follows ; 1. The distrihution of the clinical stages of 43 cervical cancers were : CIS 9, stage I 11, stage II 12, stageg III 5, stage lV 6. 2. The positive rate of SCCA of control group was 17%, and that of CEA nf control group was 12%. And the positive rate of SCCA of study group was 46.5% and that of CEA of study was 27.9%. 3. The average concentration of SCCA of control group was 0.71ng/ml and that of SCCA of study group was 8.25ng/ml(p<0.05). 4. The average concentration of CEA of control group was 1.95ng/ml and that of CEA of study group was 8.33ng/ml(p<.0.05). 5. The average concentration of SCCA by stage were 1.15ng/rnl for C1S, 1.14ng/ml for stage I, 9.72ng/rnl for stage III, 16.75ng/rnl for stage III, 21.95ng/ml for stage IV. Here, the mean value of SCCA was increased stepwise through cliinical stage, there was a correlation between the clinical stage and the concen tration of serum SCCA (p>0.05). 6.The average concentration of CEA by stage were 3.11ng/ml for CIS, 1.96ng/ml for stage I, 8.11ng/rnl for stage II, 18.92ng/ml for stage III, 19.44ng/ml for stage IV. There was not a correlation between the clinical stage and the concentration of serm CEA. 7. When the cervical cancer was divided by histologic subtypes, the average concentration of SCCA in squamous cell carcinoma of uterine cervix was 11.86ng/ml and the positive rate of SCCA in squamous cell carcinoma was 53.6%(9.46ng/ml & 58.8% in large keratinizing cell type, 15.56ng/ml & 45.5% in large nonkeratinizing cell type). And the average concentration of SCCA in adenocarcinoma was 1.32ng/ml positive rate was 40.0%. The tumor marker SCCA was more sensitive to squamous cell carcinoma rather than adenocarcinoma. 8. The sensitivities of SCCA in preinvasive cancer and invasive cancer were 22.2% and 52.9%, respectively. The average concentration of SCCA in invasive cancer was 10.04ng/ml and was more significantly elevated than of SCCA in preinvasive cancer. 9. Using SCCA & CEA together as markers for monitoring, the positive rate significantly incresaed to 70.6%(p<0.05). But measuring the two tumor marker alone, that not significantly increased. 10) . The diagnostic efficacy of SCCA in cervical cancer was 59.0%, that was higher as compaired with that of CEA. These results suggest that the serum concentration of SCCA is significantly increased stepwise by clinical stage and concomitant measurements of serum SCCA & CEA are more useful in diagnosis of cervical cancer. However measurements of SCCA and/or CEA have little efficacy in the detection of early cervical cancer considering it's low rate of positivity in early cervical cancer. We will evaluate the efficacy of two tumor markers in determining prognosis, therapeutic response and early detection of recurrence for the posttreatment patients in the future.

A case of a 58-year-old man with malignant fibrous histiocytoma (MFH) of the right ventricle is reported light and electron microscopically. This is the first case of MFH of the heart in the Korean literature. A tendency for malignant fibrous histiocytoma of the heart to occur in the left atrium of young women is suggested; this sarcoma's usual location is in the soft tissue of elderly men. The tumor consisted of spindle cells arranged in a focal storiform patterns, clusters or sheets of histocyte-like cells, benign and malignant giant cells, inflammatory cells, scattered mitotic figures and anaplasia of stromal cells. In ultrastructure the constituent of cells of the tumor are primitive mesenchymal cells, histiocytoid cells and fibroblast like cells including giant cells.

Heat shock protein of 72 kDa (HSP70) has a role in the functional modulation of sex steroid hormone receptors and in p53-associated oncogenesis and inhibits apoptosis associated with bcl-2. However, the exact role of HSP70 in the development of endometrial adenocarcinoma has not been well established. The aim of this study is to evaluate the role of HSP70 in relation with ER, PR, p53 and bcl-2 expressions and apoptosis in benign and malignant endometrial lesions. Immunohistochemical studies for HSP70, ER, PR, p53, bcl-2 and TUNEL method for apoptosis were performed in 30 cases of adenocarcinoma and 30 cases of benign endometrial lesions consisted of each 10 cases of disordered proliferative endometrium (DP), simple or complex hyperplasia (HP), and atypical hyperplasia (AH). There were no significant differences of HSP70 and bcl-2 expression rates and apoptotic index (AI) between DP, HP, AH, and adenocarcinoma. p53 expression rate in adenocarcinoma was 36.7%, but no p53 expression was identified in DP, HP and AH (p<0.05). In adenocarcinoma, HSP70 expression rate was higher in ER and PR negative adenocarcinoma (p<0.05), and p53 expression rate was higher in nonendometrioid type and FIGO grade II and III (p<0.05), but no significant difference of bcl-2 expression rate according to the histological type and FIGO grade. AI was higher in nonendometrioid type (p<0.05). There was no correlation between HSP70, p53 and bcl-2 expressions, and no significant difference of AI according to HSP70, ER, PR, p53, and bcl-2 expressions. In conclusion, higher HSP70 expression rate in poorly differentiated and ER and PR negative adenocarcinoma suggests that HSP70 inhibits ER and PR expression and may be involved in the development of poorly differentiated endometrial adenocarcinoma.

We present a case of mucous gland adenoma arising from the main bronchus of the lower lobe of the left lung in terms of clinicopathologic, immunohistochemical, and ultrastructural aspects as well as review of related literatures. The patient, a 31-year-old female, was admitted to Catholic University Medical College Hospital with complaints of coughing and purulent sputum for about seven years. The chest CT showed a severely calcified tumor in the left lower lobe of the lung. Grossly, the calcified tumor arising from the main bronchus protruded into the lumen and showed bronchiectasis of the lower lobe and atelectasis of the upper lobe of the lung. The tumor was pale brown-gray and sharply circumscribed and showed some small cystic spaces filled with mucoid material. Microscopically, most of the tumor showed dystrophic calcification. The growth pattern of the tumor is composed of cysts, tubules, and glands lined by cytologically bland columnar, cuboidal, or flattened mucus secreting cells. Electron micrograph of tumor cells showed some round or oval mucous granules measuring 0.5-1.8 micrometer.

Since 2012, outbreaks of the Middle East respiratory coronavirus (MERS-CoV) have been reported, including the Republic of Korea. To date, most of the people infected with the virus are adults. Herein we describe the clinical characteristics of cases of MERS-CoV infection among children. As of October 29, 2015, MERS-CoV has caused 34 pediatric infections, which accounts for 2.1% of all cases. The median age was 13 years (range 9 months to 17 years) and where gender has been reported (n=33), 57.6% cases were male. About half of the patients were asymptomatic and the majority of the symptomatic patients had respiratory symptoms. In general, the clinical outcome in children was favorable. Among the four patients who died of progressive pneumonia, three had documented comorbidities. MERS-CoV infection in children has a lower incidence and mortality compared to adults.
