Congenital cystic adenomatoid malformation of the lung is a rare form of congenital cystic disease of the lung and associated with developmental arrest of bronchioles in embryonic life. We report 3 cases of congenital cystic adenomatoid malformation which are classified as type I, II and III according to the morphological classification by Stocker et al. The first case was a 6-year-old female with a mass in the lower lobe of the right lung. The mass was composed of several cysts which were filled with inflammatory exudate and lined by ciliated pseudostratified columnar epithelium (type I + II). The second case was a 4-year-old female with a mass in the middle lobe of the right lung. It was composed of numerous small cysts which were uniform sized and contained inflammatory exudate. These were lined by ciliated columnar and pseudostratified columnar epithelium (type II). The third case was a stillborn female at 27 weeks of gestation. There was generalized edema and severe ascites. The left lower lobe consisted of an ill-defined solid area and small cysts. The solid lesion was composed of bronchiole-sized cysts lined by non-ciliated cuboidal epithelium (type II + III).

Recently, people living in a rapidly industrializing country such as Korea seems to have less opportunity to be exposed to Rhus and Ginkgo trees than before, which may cause a lower prevalence of sensitivity to such allergens than those reported in the past. To prove the prevalence of sensitivity in Koreans, we have tested 0. 002g and 0.0l%, Urushiols and 10% Ginkgo leaves produced by Torii company to 72 atients with or suggesting contact dermatitis. The results were as follows: 1) Twelve of 72 patients(13, 9%) showed positive reactions and two patients(2. 8 %) showed active sensitization to both 0. 002% and 0. 0l% Urushiols. Only one patient(]. 4%) reacted to 10g Ginkgo leaves, and she was also reacted to the Urushiols. 2) Age and sex distribution of the positive reactors were none under thirty, 2 in thirties, 3 in forties, 4 in fifties, one over sixty, and seven female patients outnumber three male patients. 3) Out of 5 patients having past history cf contact dermatitis to Rhus tree, only patients showed positive reactions. Out of 67 patients without past history of allergy to Rhus, 8(ll, 9%) showed positive reactions and 59(88. 1%) showed negative reactions.

This study was undertaken to observe the difference of patch test and prick test positive reactions in three groups, 20 atopic dermatitis patients, 20 chronic urticaria patients, and 20 normal controls, Twenty commercial antigens (ToriiCo.) and twenty three frozen and boiled antigens of fishes and shellfishes were used as test materials. The results were as follows: 1. No positive reaction was observed in all sixty subjects in patch test. 2 In prick test, difference in reactivity was observed among atopic dermatitis (14. 7%), chronic urticaria (8.7%), and normal control(1. 5%) 3. There was significant difference in reactivity between Torii and frozen antigens in atopic dermatitis group, but no significance in chronic urticaria and control groups. 4. Boiling altered the reactivity in tested materials in all three groups of subjects singificantly. 5. Patients with past or family history of allergic diseases showed double fold higher reactivity tban patients without any history.

Meningiomas, one of the most common neoplasms of the central nervous system, may be encountered incidentally during autopsy. Most of these tumors, however, are benign and hence, are not considered as the chief cause of death. Further, sudden unexpected death caused by meningioma is very unusual. Moreover, the diagnosis of an incidental meningioma as the cause of sudden death may sometimes be difficult. In the present report, we describe an autopsy case of a sudden, unexpected death due to a large olfactory groove meningioma accompanied by severe cerebral edema and tonsillar herniation.

The most common cause of small bowel obstruction is postoperative adhesion, and besides a hernia, metastatic or primary cancer and small bowel tumors are possible causes. Superior mesenteric artery (SMA) syndrome is a rare cause of upper gastrointestinal obstruction and is associated with debilitating conditions with marked weight loss. SMA syndrome results from the compression of the third part of the duodenum due to the narrowing of the aortomesenteric angle. We report a 28-year-old woman with SMA syndrome after acute gastroenteritis. Her stomach was severely dilated due to the duodenal obstruction and computed tomography showed the compression of the third portion of the duodenum by SMA. She was conservatively cared for and thus favorably improved.

Varieties of telepathology system had been developed and in use, but their functional capability and diagnostic accuracy are considered to be inferior to those of conventional optical microscope. This study is intended to find out: 1) the diagnostic accuracy and reproducibility rate according to the input devices and the video signals; 2) any potential technical problems of the telepathology system; 3) any possible physical and psychological impacts. We devised a virtual telepathology system using our existing microscope equipped with CCD camera unit that has no restriction of network speed. Total fifty-five surgical pathology cases from 11 different organs were selected. Three pathologists were involved in making diagnoses. The resulting diagnostic accuracies were: 1 CCD camera with composite video signal was 86.2%; 3 CCD camera with composite video signal was 93.1%; 3 CCD camera with component video signal was 95.0%. The 3 CCD camera with component video signal resulted in 95.0% diagnostic accuracy and was superior to 1 CCD camera with composite video signal. Some technical problems noted during this study were: the visual field of the virtual telepathology system was smaller by 43% than that of microscope; the difference of cell sizes between microscope and monitor; low resolution of image. Some physical and psychological symptoms were noted.

A case of papillary eccrine adenoma on the right hand of a 84-year-old woman is reported. The tumor was 1 cm in diameter, occupying the whole thickness of the dermis. Histologically, the tumor was composed of dilated tubules of various sizes with intraluminal papillary projections, and was surrounded by a fibrous stroma. An immunohistochemical study revealed that the proliferating tubules were composed of the outermost layer of alpha-smooth muscle actin-positive and the inner layer of keratin 14-negative cells. This antigen expression pattern was comparable to that of the normal eccrine secretory coil, which indicates that the tumor differentiated toward the secretory coil of an eccrine sweat gland.

Three case of plexiform schwannoma displayed multinodular masses and microscopically a multicentric pattern of growth featuring Antoni A cellular component, Verocay bodies and presence of Antoni B areas. Clinically von Recklinghausen's disease was not observed in all cases. The first patient was a 17 year old male who had a protruding nodule of walnut size which was located at the dermis of the left flank for 13 years. The second case, a 25 year old male, had an irregular whitish brown multinodular mass in the choana for 5 years. The last case, a 56 year old woman, had an ovoid yellowish brown mass with multiple nodules in the retroperitoneum.
