Korean Journal of Pathology 1987;21(4):298-302
Hyperkeratosis of the renal pelvis and ureter is a rare condition and is explained by the metaplastic change from transitional to cornified squamous epithelium. This lesion is frequently associated with, and perhaps caused by chronic urinary infection, but potentially premalignant, accompaning with carcinoma in about 10 to 20 per cent of the cases at the time of diagnosis. A case of hyperkeratosis of renal pelvis & ureter which was clinically suspected of carcinoma in a 49-year old woman with a long history of chronic pyelonephritis is presented with review of literature.

Cirsoid aneurysm of the calp is a congenital arteriovenous malformation which is the result of abnormal connections betwe:.n the external carotid artery and scalp veins with a subsequent dilatation of vascular channels nd formation of aneurysm. We report a case of cirsoid aneurysm of the scalp on the left parieto-occipital area of 14-year-old female who had had 8 x 5 x 0.8 cm sized pulsating soft mass for 2 years. 4 vessel angiog raphy revealed a arteriovenous malformation that emerge mainly from a superficial temporal artery and occipital artery of the left external carotid artery and partially from the right superficial temporal artery and drined into the left scalp vein. The mass was removed by excision with ligation of the feeding arter es and followed up for 2 years without recurrence.

The Sertoli-Leydig cell tumor is a gonadal tumor of sex-cord stromal type, similar to that seen in of the various phases of testicular development in the male. This tumor is exceedingly rare, accounting for only 0.1% to 0.5% of all primary ovarian neoplasms. It occurs predominantly in the second and third decades(mean age about 25 years), less than 10% after menopause. We investigated a case of poorly differentiated Sertoli-Leydig cell tumor of right ovary, occured in a 76-year-old woman. Grossly, the tumor measured 2, 100 gm in weight and 25 x 19 x 8 cm in dimensions. The outer surface was smooth and glistening without rupture of the capsule. Cut sections revealed a multilobulated brown solid mass with multiple cystic change. Microscopically, it showed the typical findings o a Sertoli-Leydig cell tumor. The characteristic feature is hemangiopericytoma paftem of sarcomatoid spindle cells. Therefore, we present it with a brief review of the literature.

Stress has been regrarded as one of the causes of central serous chorioretinopathy. We studied the effect of Hexamethonium (ganglionic blocking agent) on experimentaI serous chorioretinopathy following epinephrine injection in rabbits. In group 1, we injected the 0.1 % epinephrine into the rabbits through IV route for 10 days and in group 2, we addited Hexamethonium subcutaneously prior to injection of the epinephrine same term of gorup 1. We could find slight histological changes in gorup 2 as com paired with group 1, which produced serous chorioretinopathy, under the electronmicroscopic study so we would expect the preventive effect of Hexamethonium on the stress-induced serous chorioretinopathy.

We examined the obesity levels and dietary habits of 323 college students taking the course 'Health and Diet' as a part of theirnutritional education. The average percentages of body fat, BMI and RBW for subjects in this study were 16.7%, 21.5kg/m2 and -1.2% in male students and 27.3%, 21.2kg/m2 and 1.0% in female students, respectively. BMI and RBW indicated fewer cases of obesity among female students than BIA did. The average intake of energy by subjects was lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDAs of each of those nutrients. The percent RDAs of nutrient intakes of energy, protein, thiamin, and riboflavin were lower in underweight students than in students of normal and over-weight. Female students were found to skip mealsand consume sweet foods more frequently than male students. The obesity levels of students related to the number of meals eaten per day as well as the frequency of consuming sweet foods. Although, it was not possible to determine statistically, the levels obesity also seemed to correspond to the speed at which meals were eate as well as the frequency of eating salty foods. These results suggest that in order to assess obesity propertly, more research that focuses on subjects' gender should be conducted. In addition, nutritional education should emphasize the importance of intakes of energy and phosphorus for male students, and the danger of iron and calcium deficiencies for female students. We should also educate students about dietary habits which contribute to obesity such as overeating and the intake of sweet foods.

Hyperplasia of the gingivae may occur as a secondary reaction in the treatment of epilepsy with diphenylhydantoin sodium. This study is intended to investigate the incidence and dharacteristics of gingival hyperplasia in 124 epileptic patients taking diphenylhydantoin longstandingly. The results are as follows: 1. The incidence of diphenylhydantoin induced gingival hyperplasia is approximately 69.4%. 2. The individual tolerance or sensitivity may determine the incidence and severity of gingival hyperplasia and are not directly related with the duration of drug use and its dosage. 3. Gingival hyperplasia is more frequent in female patients and younger patients than male and older. 4. There is no direct relationship betwwen occurance of gingival hyperplasia and meticulous oral hygiene. 5. The mechanism involved in a causation of diphenylhydantoin induced gingival hyperplasia has not been elucidated. 6. We recommand that diphenylhydantoin may be prescribed as the drug of the first choice for the control of epileptic seizure in the adolescent female patients and children especially receiving certain dental treatments.

PURPOSE: In order to classify the involving patterns of maxillary sinus aspergillosis on CT that will be an important guidance for functional endoscopic sinus surgery(FESS) and to evaluate CT findings of each pattern. MATERIALS AND METHODS: We reviewed CT findings of 37 cases of maxillary sinus aspergillosis which were confirmed pathologically. These were classified into three patterns according to the location:the maxillary pattern(I), the infundibular pattern(11), and combined pattern(Ill). All cases were correlated with FESS findings. We also evaluated CT density, presence of contrast enahncement and calcifications, and surrounding bony changes of each pattern. RESULT: The combined pattern was most commonly seen in 24 of 37 cases(64.9%). The maxillary pattern was identified in 8(21.6%), with 5(13.5%)cases demonstrating the infundibular patttern. These patterns were consistent with FESS findings. Calcifications were seen in 28 cases(75.7%). 31 cases(83.8%) revealed hypodensity and 16cases among them showed peripheral enhancement. Central high density with peripheral low density rim was shown in 25%(2/8) of the maxillary pattern and 12.5%(3/24) of combined patttern. Surrounding bony changes were noted mainly in infundibular pattern and combined pattern. Erosion of uncinate process showed all cases of both patterns. Erosion or elevation of ethmomaxillary plate was seen in 3 of 5 cases of infundibular pattern and all cases of the combined pattern. CONCLUSION: CT fidnings of maxillary sinus aspergillosis can be classified into 3 patterns according to their distribution. These classification could be helpful for planning FESS approach. Calcifications are the most characteristic findings of maxillary sinus aspergllosis whereas CT density or enhancement pattern do not contribute to diagnosis.
