A primary skin adenoid cystic carcinoma first described by Boggio in 1975, is one of the rarest type of eccrine sweat gland carcinoma. Histologically, a tumor with typical morphologic features closely resembles adenoid cystic carcinoma was found in other tissues but in the skin must be distinguished from aggressive basal cell carcinoma. The natural history of this tumor is not yet fully determined but suggests a long indolent and progressive course. We report a case of a 77-year-old male with a small skin nodule in the abdomen.

Microcystic adenxal carcinoma is an unusual, locally aggressive neoplasm that has recently been recongized as a clincopathologic entity. Its histologic appearance includes both pilar and eccrine differentiation. Microscopically, the tumor consisted of small cysts and gland-like structures in superficial portion. In other area, basaloid cell nests and abortive hair follicles in the sclerotic stroma were seen. The cysts were filled with secretory eosinophilic material, which was positively stained with Periodic acid-Schiff and carcinoembryonic antigen. Immuno-peroxidase staining for carcinoembryonic antigen supported the dual differnetiation of this neoplasm. Despite the benign histologic appearance, there was deep and extensive infiltration of the subcutaneous tissue.

Malignant mixed mullerian tumor of the fallopian tube is an extremely rare neoplasm. To date, only 26 cases of primary malignant mixed mullerian tumor of the fallopian tube have been reported, and no report has been published in Korea. This is not surprising, since as a group these meoplasms are least likely to occur in the fallopian tube; the most common sites being the endometrium, vagina, cervix and ovary. We report a case of malignant mixed mullerian tumor of the fallopian tube ina 63-year-old woman with brief review of the literatures.

Three rare tumors of the oral cavity are presented. Lingual chondromas, approximately twenty to thirty cases appear to have been reported since the lesion was first described by Berry in 1892, which are usually seen on the lateral borders in the anterior two thirds of the tongue, while the ventral surface and the posterior third are rarely involved. Chondromas of the tonsil are of very rare occurrence, which are thought to arise as a result of metaplasia, rather than from embryonic rests, with chronic fibrosing inflammation being the inciting factor. Because of its rarity, the following cases of chondroma of the tongue and tonsil are being added to small list of such case reported in the literature.

Wilm's tumor, which is the most mommon renal tumor in childhood, has rarely been reported in adult. Diagnosis of Wilm's tumor in an adult is more apt to be accidental and is almost never suspected in the adult until discovered at operation or necropsy. Recently, we experienced a caseof Wilm's tumor in 20-year-old female patient with chief complaints of right flank pain and he maturia for two months. Renal angiogram revealed a huge renal mass replacing the upper portion of the right kidney. Nephrectomy was done under the impression of renal tumor. Grossly, the tumor was rather soft and relatively well circumscribed, measuring 13 x 8.3 cm in dimension with adhesion to renal capsule and perirenal adipose tissue. The cut surfaces revealed grayish brown in color with areas of multifocal necrosis and hemorrhage. Histologically, the tumor was composed of mainly ovoid or polygonal shaped undifferentiated blastemal cells with large areas of necrosis.

We experienced an autopsy case of esophageal atresia with tracheoesophageal fistula and other multiple congenital anomalies in a 4 days old male infant. Esophageal atresia with tracheoesophageal fistula was type C by Gross Classification. Combined anomalies were malrotation of left kidney, one left accessory renal artery form right renal artery and one left accessory renal vein from right renal vein, duodenal atresia and annular pancreas. Until now, the esophageal atresia with tracheoesophageal fistula and other multiple congenital anomalies (7 congenital anomalies) are not reported in the korean literature, except our case. Our autopsy case, it suggests that esophageal atresia with tracheoesophageal fistula has often close relation-ship with other multiple congenital anomalies.

Gatric duplication is a rare congenital anomaly. Thus for about 90 cases of gastric duplication have been recorded in the literature. It is less frequent than small intestinal or eosphageal duplication, and accounts for only 3.8% of all gastrointestinal tract duplication. Most gastric duplications are seen during the first year of life. Palpable abdominal mass and gastric outlet obstruction in infancy are most common presentation. We experienced a case of non-communicating gastric duplication. A 12-year-old girl visited St. Mary's Hospital because of indigestion, intermittent vomiting, and left upper quandrant pain for about 40 days. She have had intemittent abdominal pain with concomitant increased level of amylase since 5 years old. Physical examination showed a hen's egg sized palpable mass on left upper quadrant of the abdomen. Upper GI series and barium enema revealed only indentation of duodenal C-loop, and sonogram and abdominal CT demonstrated isolated cystic mass along the greater curvature of gastric antrum. She had taken an operation under the impression of pancreatic pseudocyst. Operation revealed a cystic mass, located along the greater curvature. There was no pathologic change in the pancreas. Microscopic findings of the cyst wall revealed normal gastric mucosal lining and common muscle layer, shared with gastric antral muscle layer.

BACKGROUND: Exercise testing is an importnat diagnostic and prognostic procedure in the assessment of patients with ischemic heart disease. But standard ST-segment depression criteria was not high enough to estimate coronary srtery disease. Recently, the heart rate adjustment of ST segment depression, ST segment/heart rate slope and index, have been proposed as a more accurate criteria for diagnosing significant coronary artery disease. The objective of this study was to compare the discriminating power of proposed ST segment/heart rate slope and index with that of a standard method of assessing exercise-induced ST segment depression for estimating coronary artery disease. METHODS: Sixty nine patients with ischemic heart disease were studied with exercise treadmill testing and coronary angiography. Computer-measured ST-segment amplitudes were obtained and analysis of the heart rate-adjusted ST segment depression(ST/HR slope and big up tri, Delta ST/HR index) was done. The sensitivity, specificity, and extent of coronary artery disease on each criteria were compared. RESULTS: 1) The sensitivity of big up tri, Delta ST/HR index partition of 1.6uV/beats/min was slightly higher(83%) and the specificity of ST/HR slope partition of 2.4uV/beats/min was higher(87%) than the standard exercise electrocardiographic criteria. 2) Early onset of ischemic ST-segment depression, profound ST-segment depression(> or =2mm), and downsloping ST-segment were associated with more extensive coronary artery disease. 3) On ST/HR slope, no CAD was 1.7+/-0.26uV/beats/min, one vessel disease was 2.6+/-0.34 uV/beats/min, two vessel disease was 2.7+/-1.36uV/beats/min, one vessel disease was 2.8+/-0.35uV/beats/min, and on big up tri, Delta ST/HR index, no CAD was 1.8+/-0.38uV/beats/min, one vessel disease was 2.8+/-1.36uV/beats/min, two vessel disease 3.4+/-1.44uV/beats/min, and three vessel disease was 3.7+/-2.95uV/beats/min. The increment of ST/HR slope and big up tri, Delta ST/HR index were associated with the coronary artery disease and its severity, but the correlations were not high enough. CONCLUSION: The heart rate adjustment of ST segment depression was not high enough for improved detection of coronary artery disease, compared with standard ST-segment depression criteria. But these indexes can be improved the clinical usefulness of the treadmill exercise test for coronary aretry disease.
