Eccrine spiradenomas are clinically characterized by a solitary, tender mass and they are situated on the upper parts of the body, predominantly on the ventral aspect. We herein report two cases of eccrine spiradenoma in 35-year-old man and 53-year-old woman, which located on upper extremity and inguinal region. The masses are round, well circumscribed and measuring 0.7x0.5x0.5 cm, 5x4.5x3 cm in size, respectively. Histopathologically, the tumor consists of masses of two types of cells, intensely staining cells and pale staining cells, usually arranged in chains, cords and pseudoglands. Immunostainings for low molecular cytokeratin, high molecular cytokeratin, carcinoembryonic antigen, and S-100 protein show positivity in neoplastic cells. Electron microscopically, the tumor was composed of three types of cells, i. e. 1) round or ovoid tumor cells in shape with scanty cytoplasm and poorly developed intracytoplasmic orgenelles, 2) spindle shaped dark cells interconnected by desmosomes, 3) large epithelial cells with abundant cytoplasm and cytoplasmic intermediate filaments which formed glandular structures. The large epithelial cells joint each other by desmosomal attachments and luminal cells featured small numbers of microvilli, but either secretory granules nor ductal type granules were noticed.

Clinical EPS was performed in 16 normal adults without evidence of conduction disease on the surface standard 12 lead electrocardiogram in order to provide normal electrophysiological values of the sinus node function and AV conduction. EPS was also performed in 15 patients with sick sinus syndrome and 10 patients with AV conduction disturbance to evaluate the clinical usefulness of EPS in detecting sinus node dysfunction and AV conduction disturbance. The results were as follows. 1) The results of sinus node function test in the normal group were m-SNRT 853+/-198msec(range 800-1,560msec), c-SNRT 230+/-66msec(range 120-370msec), and %m -SNRT/SCL 127+/-11%(range 114-149%). 2) In 15 patients with SSS, the M-SNRT were ranged from 1,270 to 12,330msec and 10 patients(66%) had significantly increased m-SNRT exceeding 1,560msec. The c-SNRT were ranged from 230 to 10,730msec and 13 patients(83%) had significantly increased c-SNRT exceeding 370msec. The % m-SNRT/SCL were ranged from 136 to 770% and 12 patients(80%) had significantly increased % m-SNRT/SCL exceeding 150%. 3) The SACT in normal group were 84+/-14msec(range 70-105msec) measured by continuous atrial pacing method and 80+/-19 msec(range 60-115msec) measured by atrial extrastimulation method. 4) In SSS, the SACT measured by continuous atrial pacing method was ranged from 80 to 1,050msec and 11/12 patients(92%) had significantly increased SACT exceeding 112 msec. The SACT measured by atrial extrastimulation method was ranged from 90 to 310msec and 7/8 patients(88%) had significantly increased SACT exceeding 118 msec. 5) C-SNRT, % m-SNRT/SCL, and SACT were more useful in detecting sinus node dysfunction than m-SNRT. 6) The AV conduction intervals in normal group were PA interval 17+/-6(range 5-25msec), AH interval 96+/-18 msec(range 70-135msec), and HV interval 46+/-7msec(range 35-55msec). 7) Rapid atrial pacing induced Wenckebach type second degree AV block proximal to H at pacing rate of 90 to 190/min in 14/16 normal adults. 2 patients maintained intact AV conduction upto maximum pacing rate of 200/min. 8) His bundle electrogram showed the site of AV block in 9 of 10 patients with AV conduction disturbances. The sites of AV block were AV nodal area 1 case, intraHis bundle 4 cases, and infraHis bundle 4 cases. 9) EPS provided a good supportive information that was useful in selecting pacemaker therapy in a patient with chronic bifascicular block who revealed prolonged HV interval and infraHis bundle block at a pacing rate of 70min. 10) The refractory periods of AV conduction system in normal group were AERP 274+/-54msec (range 170-410msec), AVN-FRp 467+/-74msec(range 285-600msec), AVN-ERP 341+76msec(range 190-460), and V-ERP 280+/-25msec(range 240-320msec).

Transfer of large quantities of fetal blood across the placental barrier to the maternal circulation is a rare occurrence which results in severe anemia in the newborn infants. This phenomenon is believed to occur most often during labor and delivery and apparently, is more frequent when abnormal obstetric conditions are present. However, fetal erythrocytes have been identified in the naternal circulation throughout most of pregnancy indicating some degree of constant or intermittent transplacental transfusion. We experienced a case of stillbirth due to large amount of fetomaternal transfusion. Acid elutionl test of maternal blood was positive and direct and indirect Coombs test was negative. Ultrasonographic finding on abdomen and cranium to rule out the internal hemorrhage was normal. We report a case of stillbirth due to fetomaternal transfusion with a brief review of related literatures.

In the present study, immunohistochemical detection of p53 oncoprotein was performed to determine whether the grade of differentiation and the histologic type of gastric adenocarcinoma, and the degree of atypia accompanied with adenoma can be related to p53 mutation. Paraffin sections of 22 gastric adenomas and 56 gastric adenocarcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin peroxidase complex staining procedure. The obtained results were as follows; 1. All the 22 cases of adenomas and 16 cases of well differentated adenocarcinomas showed uniformly negative staining. 2.Seven of 18 cases of moderately differentiated adenocarcinomas(39%), and five of 30 cases of poorly differentiated adenocarcinomas(17%) exhibited p53 protein expression. 3. Three of 29 cases of diffuse type (10%) and 9 of 19 cases of intestinal type(47%) exhibited p53 protein expression. These results suggest that p53 mutation is important in carcinogenesis of the intestinal type of gastric adenocarcinoma, and there is no correlation between the differentiation of gastric adenocarcinoma and the degree of p53 oncoprotein overexpression.

There have been so many methods described for the correction of the deviated noses but it is difficult to get satisfactory results and recurrence rate is high. There is no exact explanation why the recurrences are so high and no estabished guides for techniques according to the surgical pathology. We found the classical swinging door technique effective in cases where the caudal septum deviated from the midline. However, where the caudal septum and the tip stay in the midline, scoring or submucosal resection do not work well enough to cortet them. We used the reverse swinging door technique of our own. After elevation of mucoperichonodrium, we did sagittal section in the posterior septum and moved the septum to the midline on the pivot point of the caudal septum and. The gap created in the posterior portion of the septum were filed with bone grafts, cartilage grafts or Medopor, which were sutured to the septum, We did this technique with or without osteotmies in 56 deviated noses for last 5 years. The results were very satisfactory and there was no complication.

We report a case of dedifferentiated liposarcoma of retroperitoneum as a recurrent form in a 41 year old male. The patient received a extirpation for retroperitoneal mass and diagnosed as myxoid liosarcoma 4 years ago. The patient experienced 3 recurrences over a period of 4 years and diagnosed as myxoid liposarcoma in the second, third recurrence also. Histologically, the mass was composed of several clearly distinct elements : well differentiated liposarcoma, myxoid liposarcoma, myxoid malignant fibrous histiocytoma, poorly differntiated sarcoma, and fibrosarcoma. Immunohistochemically, S-100 protein was expressed in the area of spindle cell sarcoma, well differentiated liposarcoma, and malignant fibrous histiocytoma but alpha-1-antichymotrypsin was only expressed in the area of myxoid malignant fibrous histiocytoma.

Occurrence of a retroperitoneal duplication cyst associated with a heterotopic pancreas is rare. We report a case of a retroperitoneal duplication cyst associated with a heterotopic pancreas. A 35-year-old male was admitted, presenting with back pain. A pelvic computed tomographic scan disclosed a 10 cm-sized cystic mass filling the lower pelvis and displacing the rectosigmoid colon anteriorly. Histologically, the cyst wall was lined partly by mucin-secreting columnar epithelium, showing atypical hyperplasia and partly by a gastric fundic-type and a colonic-like mucosa. Beneath the epithelium, organized bundles of smooth muscle were arranged in two layers analogous to smooth muscles layers of the bowel and a small piece of pancreatic tissue were present in the smooth muscle wall of the cyst.
