1.Multiple Chorioangiomas of Placenta: A case report associated with repeated abortions and intrauterine fetal death.
Korean Journal of Pathology 1985;19(1):131-135
Chorioangioma is the most common primary tumor of the placenta. It is widely accepted to be formed from hamartomatous proliferation of angioblastic cells in early placenta. According to groups who systematically examined the placentas with the greatest scrutiny, the incidence of chorioangioma is 1~1.2% of all placentas examined. The clinical implication of chorioangioma has been emphasized due to its high association with hydramnios, antepartum and postpartum hemorrhage, premature onset of labor, or intrauterine fetal distress or death. The authors experienced a case of a 38-year old multigravida who had undergone 4 consecutive spontaneous abortions. The fifth pregnancy was carried to 35 weeks whereupon a dead fetus was delivered. The placenta was enlarged(950 gm) with multiple protruding nodules into the fetal surface. Microscopically, the nodule was composed of many vilous structures lined by chorionic epithelium. Within these structures was proliferation of endothelial lined capillaries some of which demonstrated ectatic change.

BACKGROUND: This study investigated the effectiveness of reinforced contact precautions and active surveillance cultures (ASCs) in reducing the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and other healthcare-associated infections (HAIs). METHODS: A before- and after-experimental study was performed at the intensive care unit (ICU) in a university-affiliated hospital. Reinforced contact precautions were applied to all patients, and ASCs for MRSA were performed for newly admitted patients at the time of admission and once a week thereafter. The HAIs were investigated in accordance with the National Nosocomial Infections Surveillance (NNIS) definitions and compared before and after the interventions. The data were analyzed using descriptive statistics. RESULTS: The number of HAIs caused by MRSA decreased from 2.2 to 0.5 per 100 patients discharged (P=0.02) and from 3.6 to 1.0 per 1,000 patient-days (P=0.032). The number of overall HAIs decreased from 7.6 to 4.0 per 100 patients discharged (P=0.011) and from 12.7 to 7.3 per 1,000 patient-days (P=0.034). The invasive device-associated infections caused by MRSA and other pathogens decreased, but the decrease was not statistically significant. CONCLUSION: Reinforced contact precautions and ASCs were effective in decreasing both MRSA infections and overall HAIs in the ICU. Further, it was assumed that the incidence of device-associated infections would have decreased if the intervention period was extended.

Five cases of ovarian serous borderline tumor associated with multiple peritoneal implants were analysed. The age of 5 patients ranged from 34 to 45(mean: 39) years at the time of diagnosis. Two patients presented with secondary infertility underwent hyperstimulation of the ovary under the in vitro fertilization program. One patient was presented with abdominal pain and the remaining two with lower abdominal mass accompanied by abdominal pain. Serous surface papilloma of borderline malignancy, involving one or both ovaries, was present in all 5 cases and papillary serous cystic tumor of borderline malignancy was associated simultaneously in one or both ovaries in all cases. Marked adhesions between the pelvic organs, and multiple granularities and nodularities of the omentum and peritoneum were noted. Microscopically, the peritoneal lesions were composed of noninvasive implants of tumor cells and pasmmoma bodies on the surface of entire pelvic and abdominal organs. Flow cytometric analysis of nuclear DNA content from paraffin-embedded tissue fo primary ovarian tumor classified as aneuploidy in 3 cases and as diploidy in 2 cases. The DNA index of the aneuploid tumors ranged from 1.21 to 1.37. Four patients underwent hysterectomy, bilateral salpingo-oophorectomy and partial omentectomy in which two were followed by chemotherapy and one case underwent bilateral salpingo-oophorectomy.

Three cases of hydatidiform mole with a coexisting fetus are described. In two cases, flow cytometric analysis of nuclear DNA content from paraffin-embedded, molar tissues and normal-appearing placental tissues showed diploid pattern. One case had karyotypes of 46, XX both in fetal skin fibroblasts and in molar tissues. Microscopically, the villi showed diffuse hydropic swelling with circumferential trophoblastic proliferations and consistent with the diagnosis of complete mole. Two patient had persistent gestational trophoblastic neoplasia on the follow-up. Therefore, in cases of hydatidiform mole with a coexisting fetus, dizygotic twin pregnancies composed of a normal pregnancy from one ovum and a complete mole pregnancy from the other ovum must be considered and the patients should be followed with serum beta-hCG measurements.

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) is a novel alternative treatment for differentiated early gastric cancer (EGC) without lymph node metastasis. We conducted this study to verify the therapeutic usefulness of ESD for treating differentiated EGC compared to that of surgery. METHODS: This is a retrospective cohort study of 382 patients treated with differentiated EGC from March 2006 to May 2010. The propensity score yielded 275 matched patients. They were divided into an ESD group of 175 people and a gastrectomy group of 100 people. The patient demographics, pathologic characteristics, length of hospital stay, complication rate and survival rate were compared. RESULTS: The complication rate was higher for the gastrectomy group than for the ESD group (15.0% vs. 5.1%, p=0.007). The average length of patient hospitalization was longer after gastrectomy than after ESD (8.6 days vs. 2.4 days, p<0.001). There were two cases of mortality in the surgery group within 30 days of procedure. The 5-year survival rates of the two groups did not show a statistically significant difference (92.0% vs. 93.3%, p=0.496). CONCLUSIONS: The long-term survival rates of ESD and gastrectomy were not significantly different. The complication rate was lower for ESD than for gastrectomy, and the length of hospital stay was shorter after ESD than after gastrectomy.

Parry-Romberg syndrome, first described in 1825 by Parry and in 1846 by Romberg, is a rare disorder characterized by a progressive hemifacial atrophy of the skin and adipose tissue and atrophy of muscle, cartilage, and underlying bony structures. It is sometimes accompanied with such complications as ophthalmologic abnormality, localized alopecia and neurologic symptoms, for example, contralateral Jacksonian epilepsy, trigeminal neuralgia, migrane and hemiplegia. The onset is slow and progressive, starting at the first or second decade of life and lasting for 2-10 years, ending with a face being "burned out". It is often associated with epilepsy but the link between these two conditions is poorly understood. In patients with progressive hemifacial atrophy, a high incidence of abnormal neuroradiologic findings in the brain has been reported. Brain MRI findings include cerebral hemiatrophy, cortical calcification, unilateral focal infarction in the corpus callosum, diffuse deep and subcortical white matter signal changes and mild cortical thickening. We report a case of Parry-Romberg syndrome in a 5-year-old boy who had a progressive Rt. facial hemiatrophy with intractable epilepsy and basal ganglia calcification from brain MRI.

Angioleiomyoma is a rare benign tumor arising from vascular smooth muscle which commonly develops on the lower extremities of middle-aged women. It is rare to occur on the fingers. Angioleiomyoma is classified into three histological subtypes; solid, venous and cavernous. The solid type is most common but the cavernous type is very rare. We report a case of a 53-year-old female with a digital cavernous angioleiomyoma. The patient had a 2-year history of an asymptomatic and slowly enlarging 1.3x1.0 cm-sized subcutaneous nodule on the distal phalanx of her second left finger. Histopathologic examination showed a well-demarcated nodular tumor in the dermis, which composed of numerous, dilated vessels and bundles of smooth muscle fibers.

Epithelioid blue nevus is a rare variant of blue nevus that has been recently described in patients with the Carney complex. However, sporadic cases have been reported even without the Carney complex. It typically presents as an asymptomatic, blue-gray, smooth-surfaced macule or papule occurring most often on the extremities and trunk. However, a few cases occurring on the mucosa have been reported. A 21-year-old man presented with a 0.4-cm sized solitary dark brownish or black papule on the lower lip. On histological examination, the major part of the specimen showed an infiltration of intensely pigmented epithelioid cells, the rest was composed of mildly pigmented spindle cells. There was no junctional activity, necrosis, or cellular atypia. These findings were consistent with epithelioid blue nevus. The patient did not exhibit any features associated with the Carney complex. No evidence of recurrence was observed during the follow-up period of 24 months. Herein, we report a rare case of epithelioid blue nevus arising on an unusual site.
