Intestinal malrotation is a constellation of a wide spectrum of embryologic failures of rotation and fixation of the gut, resulting in a narrow-based attachment of the mesentery and the presence of abnormal peritoneal (Ladd's) band. These abnormalities predispose to midgut volvulus, intestinal obstruction and internal herniation. We experienced a case of intestinal malrotation complicated by midgut volvulus in a 4-year-old girl who presente with abdominal pain, abdominal distension and melena. The diagnosis was made by abdominal CT scan, which showed "whirl sign." The diagnosis was confirmed by surgery. A brief review of literature ensues.

Health belief is an important factor influencing the performance of health behaviors. Young adulthood is a critical period to establish health beliefs and behaviors for a healthy life. As health professionals, nurses can help young people establish more positive health beliefs and carry out health behaviors more effectively. But before attempting to help them, it is necessary to identify their health beliefs and behaviors. The purpose of this study was to identify the health beliefs and health behaviors of university students in Korea. Subjects for this study were 2000 students from 10 universities, but data from only 1605 subjects was included in the analysis. Data were collected from May 5th, 1998 to June 21th, 1998. Instruments used in this study were two tools to measure 'health beliefs' and 'performance of health behaviors' that had been developed and used in previous research. Cronbach's alphas were .8737 for the tool for health beliefs and .8385 for the tool for health behaviors. The results of this study are as follows. (1) Average score of the subjects was 117.68 for health belief and 95.15 for performance of health behaviors. (2) There was a significant correlation between the health belief and the performance of health behaviors(r= .419). (3) School year, major, health status, and experience of disease in the students were important factors in the explanation of health belief(28.8%). (4) Health belief, major, health status, school year, sex, age, experience of disease in family members were important factors in the explanation of the performance of health behaviors (21.2%).

Hibernoma is very rarely encountered and is expressed in the various names including "lipoma of brown fat", "fetal lipoma", and "lipoma of embryonic fat". In our knowledge, only about 50 cases have been reported in the literature of the Western world, and no case reports have been published in Korea. In May 1986, we experienced a case of hibernoma occuring in a 16 old years boy. On physical examination, a relatively well defined nodule was noted on the right scapular region. A total removal of the lesion was done under the clinical diagnosis of epidermal inclusion cyst. On gross examination, the specimen consists of three irregularly shaped portions of yellowish brown soft tissue, measuring up to 0.8 cm in greatest dimension. Microscopically, the tumor showed distinct lobular pattern separated by fibrovascular bands. The lobules were composed of multivacuolated or eosinophilic granular cells showing centrally located small unclei. A brief review of the literature was done.

Arteriovenous malformation of the uterus is rarely encountered. It is potentially lethal because of profuse, uncontrollable bleeding at the time of diagnostic dilatation and curettage. To our knowledge, only 38 cases of localized uterine arteriovenous malformation have been reported in English and Korean literature. Recently we experienced a case of uterine arteriovenous malformation in a 28-year-old multiparous woman. Under the clinical impression of uterine tumors or arteriovenous malformation, a total hysterectomy was done. Gross examination demonstrated a vascular nature of the mass in the posterior wall of the fundus. Microscopically, there was an ill-defined mass composed of numerous irregular, anastomosing large vessels with various diameters.

The clear hidradenoma, generally regarded as an eccrine sweat gland origin, is an uncommon tumor and occurs as a slowly growing, usually solitary nodule. The histologic patterns varies from one tumor to another and in different parts of the same tumor. The histologically variable patterns, therefore, are expressed in various names, including nodular hidradenoma, eccrine acrospiroma, squamous poroadenoma, and solid cystic hidradenoma. During the past 16 years the authors experienced 5 cases of clear cell hidradenoma which were diagnosed by the histopathological examination of the tumor mass removed by surgical excision. Clinical and pathological features were reviewed and the following results were obtained. 1) The mean age was 34 years with a range from 27 to 45 years. Three were male and two female. 2) The chiefr complaint was intradermal or subcutaneous nodules for a period of several years to 15 years. All cases occured as a solitary nodule without a distinct predilection for certain sites. A nodule which situated in the dermis and was accompanied by superficial ulceration was elevated above the skin surface in one case. 3) Grossly, the tumors were relatively well circumscribed and composed of multiloblated masses in 4 cases. They ranged in size between 1.5 and 3.5 cm. 4) Microscopically, all cases disclosed lobulated solid masses separated by varying amounts of collagenous connective tissue. There were often cystic spaces, which were lined by a single row of cuboidal cells in four cases and were bordered by tumor cells in remaining one case. These cysts contained a faintly eosinophilic homogeneous material. On solid portions of the tumor there were two types of cells (clear cell and polygonal cell), the proportions of which varied from tumor to tumor in three cases. The remaining two cases were predominantly composed of clear cells. Tubular lumina which were lined by cuboidal or columnar ductal cells were found in two cases. Areas of squamous differentiation and squamous eddies were seen in one case. Intracytolasmic PAS-positive materials were shown in all cases, but diastase-resistant PAS materials in two cases.

Pleomorphic adenoma presenting as primary lesion of the bronchus is very rarely encountered, and in our knowledge only 6 cases have been reported in the literature of the western world, and no case report has been published in Korea. Currently, we experienced a case of bronchial pleomorphic adenoma occuring in a 38 years old woman. On X-ray examination, hazy density in the right upper lobe and emphysematous change in the right lower lobe were noted. A right pneumonectomy was done under bronchoscopic diagnosis of bronchial adeoma. The pathologic examination of the present case showed a polypoid endobronchial tumor, 1.4 x 1.1 cm (with extraluminal portion, 2.2 x 1.7 cm) in the right upper bronchus. The microscopic examination revealed a pleomorphic adenoma showing same morphology as those found in the salivary gland. This case, therefore, was believed to be a genuine example of bronchial pleomorphic adenoma of salivary gland type. We compared this case with 6 cases in the literature.

Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.

Orbital mesenchymal chondrosarcoma, first described by Luis et. al in 1971, is a very rare tumor of characteristic histologic features. A 21-year-woman was admitted with a 4-month histoiry of rapidly progressive proptosis and visual disturbance. Right orbital exenteration was performed under the clinical diagnosis of orbital calcifying tumor. Grossly, the tumor presented as a multibloblated, circumscribed mass that measures 5.5 cm in the greatest dimentsion. Cut sections resembled ordinary chonrosarcoma. Microscopically, the tumor was composed of undifferentiated mesenchymal cells, interspersed nodules of well differentated cartilagenous tissue, areas of gradual transition from undifferentiated mesenchymal cells to cartilage, and hemangiopericytoma-like areas. A brief summary of the histopathological aspect of this tumor and a review of literature are presented.
