Placental site nodules and plaques have been recently described to designated single or multiple, well-circumscribed, rounded lesions at the placental site, composed of viable or degenerating intermediate trophoblastic cells and extensive hyalinization between the cells. We described clinicopathologic findings of 14 cases of placental site nodules and plaques. The age of 14 patients ranged from 25 to 39(average 33) years and all of them had been pregnant in the past. Ten of them presented with vaginal spotting, which was preceded by recent pregnancy in only 3 cases. Three patients presented with secondary infertility and one with secondary infertility and vaginal spotting. Urine pregnancy tests were negative in all 14 cases at the time of presentation. Ultrasonographic examination disclosed abnormalities in only 3 cases and the remaining cases were normal. Hysterosalpingography was performed in 3 patients who presented with 2 degrees infertility and revealed moderate to severe intrauterine adhesions. Microscopically, chronic endometritis of varying degrees evidenced by plasma cells and eosinophiles were present in all cases and these were more prominent in the vicinity of the lesions. It is presumed that the placental site nodules and plaques are not sloughed at the time of menstruation and it may cause chronic endometritis or intrauterine adhesions at any time after previous delivery.

Double primary cancer is defined as the case of primary malignant tumors, which must be arise in different sites and have a different histologic appearences. The number of reported cases of double primary malignant tumors has increased in recent and the occurrence of multiple primary cancers in the same individuals is one of the interesting subjects for investigation and research in relation to the carcinogenic mechanism and/or genetic factors. We have experienced a case with double primary malignant tumors of different site origins such as stomach adenocarcinoma and rectal adenocarcinoma, which were diagnosed by biopsies with gastro and colono fiberscopy. For its great rarity, we report this case with review of literatures.

PURPOSE: We examined the ability of alpha-phenyl-tert-butyl-nitrone (PBN), an electron spin trapper, to determine the neuroprotective effect in the argon laser induced ischemic rat retina model. METHODS: After ischemic condition of rat retina was induced by argon green laser, PBN was given intraperitoneally at 50 or 100 mg/kg and normal saline was injected to control group. After 24 hours, 48 hours, and 7 days, the neuroprotective effect of PBN was examined by electroretinogram (ERG) and after 7 days, the enucleation of eyes was performed and histologic findings were compared by light microscopy and transmission electron microscopy. RESULTS: We found relatively reduced amplitude of ERG wave in the PBN injected group but not so greatly reduced as in normal saline control group. The retinal ganglion cell (RGC) layer and the number of RGCs were affected by acute ischemic changes but in the group of PBN treatment, the cell membrane was well preserved and vecuoles formation, cytoplasmic destructions, nuclear chromatin condensation were reduced. CONCLUSIONS: Systemic administration of PBN can ameliorate an argon laser induced retinal ischemia. Further investigations are necessary to decide effective dose without toxicity and to find more convenient methods of administrations.

Squamous cell carcinoma of the stomach is very rare with a reported incidence of 0.09% of all resected gastric malignancies. We report here two cases of squamous carcinomas and a brief review of literatures. A 74-year old female was admitted because of epigastric pain and vomiting. Abdominal CT, UGI and endoscopic findings revealed a Borrmann type III gastric cancer on the posterior wall of the antrum with pyrolic obstruction and multiple liver metastases. Palliative distal gastrectomy with gastrojejunostomy was performed. The histopathologic diagnosis was adenosquamous cell carcinoma. She died of malnutrition and multiple organ failure 5 months after the operation. The other case was a 53-year old male admitted because of indigestion. Abdominal CT, UGI and endoscopic findings revealed a Borrmann type III gastric cancer on the greater curvature of the antrum with multiple enlargements of the perigastric lymph nodes. Distal subtotal gastrectomy with gastrojejunistomy was performed. The histopathologic finding revealed squamous cell carcinoma. He was discharged after FEC(5-FU, etoposide, cispatin) chemotherapy uneventfully.

Ovarian cysts are the most frequent, prenatally diagnosed intra-abdominal cysts. Fetal ovarian cyst often presents complication such as torsion and seems to be an indication for surgical intervention. In this study, we reviewed pre- and post-natal medical records and ultrasonography of 17 fetuses that were diagnosed with ovarian cysts. In a total of 17 cases, postnatal surgery was performed in 7 infants. Of these cases, four cases of ovarian cyst torsion were confirmed. In the remaining 10 fetuses, one case regressed completely during pregnancy, and the other nine cases including two complex cysts resolve spontaneously after birth. Postnatal symptomatic cysts or cysts with a diameter greater than 5 cm that do not regress or enlarge should be treated, but uncomplicated asymptomatic cysts less than 5 cm in diameter should only be observed and reassessed by serial ultrasonography. If they regress spon-taneously, no surgical intervention is necessary independent of their sonographic findings.

BACKGROUND: Because of the power of HRCT to detect the minute changes in lung parenchyme and the advantage of noninvasiveness, it may be the ideal method of follow-up evaluation of the patients with diffuse interstitial pulmonary fibrosis. So the aim of the study is to find out whether the change of HRCT during the course of the disease can represent the change in symptom and pulmonary function rest. METHODS: Thirteen patients with diagnosis of diffuse interstitial pulmonary fibrosis who had more than two times of HRCT during the course of disease were studied. The extent of the disease in HRCT was measured at three levels using image analyzer The ralationship between the percent change in the disease extent in HRCT, symptom score, and pulmonary function testis were analysed. RESULTS: The change of disease extent in HRCT has good correlation with the change in dyspnea and diffusion capacity(r=0.716, p=0.0012). But there was no correlation between the change of HRCT and FVC or TLC. Also significant inverse correlation was noted between the change in dyspnea and diffusion capacity(r=-0.707, p=0.0047). CONCLUSION: These data suggest that HRCT may be a good method of follow-up in diffuse interstitial pulmonary fibrosis.
