BACKGROUND: The wall of ovarian dermoid cysts shows various kinds of morphologic patterns. Some of them resemble the features of epidermal and epidermal appendageal tumors. OBJECTIVE: The purpose of this study is to classify the morphologic features of the wall of ovarian dermoid cyst from the dermatohistopathologic viewpoint. METHODS: H&E stained slides of 203 ovarian dermoid cysts were reviewed RESULTS: Thirteen different patterns of morphologic features were found. They included features of organoid nevus, sebaceous hyperplasia, steatocystoma multiplex, epidermoid cyst, nevus comedonicus, epidermal nevus, apocrine hidrocystoma, syringoma and trichilemmal cyst. CONCLUSION: Various epidermal and epidermal appendageal tumors may be associated with ovarian dermoid cyst.

A case of malignant epithelial mesothelioma of the peritoneum diagnosed by fine needle aspiration cytology is described. The smear showed many individually scattered or clustered large round malignant epithelial cells intermingled with relatively small nonneoplastic mesothelial and mesenchymal cells. Papillary configurations with thick fibrous core were also seen. The malignant cells were virtually reminiscent of reactive mesothelial cells but they were larger in size and had more prominent nucleoli and more frequent binucleated or multinucleated cell formations than reactive mesothelial cells. The characteristic features of malignant cell of mesothelioma compared with the metastatic adenocarcinoma were relatively uniform cellular size, prominent round nucleoli, large round vesicular nuclei with finely granular chromatin pattern, smooth nuclear membrane, abundant glassy cytoplasm rather than bubbly mucin-containing cytoplasm and fuzzy cell border.

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.

Since May 1981, the standard method of treatment of the femoral shaft fractures at the Daejeon EuIji Deneral Hospital has been the closed intramedullary nailing technique of Kuntscher. We performed intramedullary nailing on thirty-five fractures of femoral shaft in 35 patients. Closed intramedullary nailing was used in twenty-eight femora and open intramedullary nailing with cerclage wiring in seven fractures, in which large butterfly fragment was present, precluding control of rotation or length, or both. The overall rate of union was 97 percent. The range of motion of the knee at follow up was good in 80%, fair in 14%, poor in 6% (Good Full extension; loss of flexion less than 10 degrees. Fair Any loss of extension;loss of flexion of 10 to 50 degrees, Poor Loss of more than 10 degrees of extension; range of flexion-extension less than 90 degrees). The advantages of this technique include the negligible risk of infection, the rapid stabilization of fracture, thus facilitating management of other associated injuries, the rapid return of function of the knee, and early union of fracture and return to work. It is authors' opinion that when proper equipment and expertise are available, than closed intramedullary nailing is the treatment of choice not only for simple uncomminuted fracture of the femoral shaft but also for open comminuted fractures.

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.
